mntl-sc-block-callout-body mntl-text-block\">\n<ul>\n<li>Keratin treatments make thick or frizzy hair smoother and more manageable without affecting its natural structure.<\/li>\n<li>Brazilian Blowouts provide straight, sleek hair using an amino acid formula that avoids formaldehyde.<\/li>\n<li>Both treatments require proper aftercare, including avoiding washing hair for several days and using sulfate-free shampoos.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p id=\"mntl-sc-block_2-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There was once a time when those who wanted smooth hair had to <em>literally<\/em> iron it out. Now there are tools and technologies specifically designed to straighten strands instantly. Among the most popular? Semi-permanent salon-grade treatments that leave hair smooth with zero effort on your part.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_4-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The two biggies, of course, are keratin treatments and Brazilian blowouts. Both of these treatments are lauded for their ability to reduce frizz and can deliver jaw-dropping results. But though they may offer similar effects, they\u2019re two entirely different treatments. Understanding how they work (and who they&#8217;re best for) is critical for choosing which one\u2019s best for you.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_6-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> \u201cBoth treatments are great for smoothing, but the main difference is what kind of results they can give,\u201d says Christina Giarrizzo, a celebrity hairstylist at Voel Hair in New York City. \u201cA Brazilian blowout will eliminate frizz and even straighten curly hair, while keratin will make your hair straighter and more manageable without damaging the integrity of the hair\u2019s structure.\u201d\u00a0\n<\/p>\n<p id=\"mntl-sc-block_8-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> So, which one will give you the smoothed-out strands of your dreams?

Additionally, this treatment can also be helpful for those who have thicker or more coarse textures and are looking to make their hair more manageable.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_18-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> That said, \u201cThe best person to determine if your hair is suitable for a keratin treatment is a licensed, professional salon stylist,\u201d says Combs. \u201cThe first step to receiving a keratin treatment is to schedule a consultation with your stylist. During the consultation, your stylist will ask questions to help determine which treatment is best suited for your hair type and hair goals.\u201d<\/p>\n<h3 id=\"mntl-sc-block_20-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Not Ideal Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_21-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> If you already have very thin, fragile hair, this treatment isn&#8217;t for you. It even can cause more damage than good. \u201cBecause keratin is designed to help thicker and coarse hair more manageable, it&#8217;s not ideal for people with superfine hair or those prone to breakage,&#8221; says Giarrizzo. &#8220;Especially considering the high heat of the flat iron used.&#8221;\n<\/p>\n<h3 id=\"mntl-sc-block_23-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Typical Cost <\/span><\/h3>\n<p id=\"mntl-sc-block_24-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The average keratin treatment costs between $200 and $800. \u201cThe price shifts based on several factors, including the length and density of a client\u2019s hair, the amount of time the application takes, and the formula longevity, which can span from 10 weeks to five months,\u201d says Combs.<\/p>\n<h3 id=\"mntl-sc-block_26-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> How Long Does it Last? <\/span><\/h3>\n<p id=\"mntl-sc-block_27-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> A keratin treatment lasts between four weeks and five months, depending on the formula that was used and how well you\u2019re caring for your hair.\n<\/p>\n<h2 id=\"mntl-sc-block_29-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> What Is a Brazilian Blowout? <\/span><\/h2>\n<p id=\"mntl-sc-block_30-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowouts are a type of keratin treatment that takes things one step further to smooth and straighten strands.\u00a0This treatment uses a proprietary blend of amino acids and proteins (including keratin) and is devoid of the formaldehyde that\u2019s often found in keratin treatments. \u201cA Brazilian blowout uses a liquid keratin formula that creates a layer over each strand of hair, and is sealed in with heat, to help straighten and smooth hair,\u201d says Harry Josh, a celebrity hairstylist and Kerasilk ambassador. Unlike keratin treatments, which are fairly \u201cone size fits all,\u201d Brazilian blowouts can be customized depending on the texture you\u2019re trying to achieve.<\/p>\n<figure id=\"mntl-sc-block_32-0\" class=\"comp mntl-sc-block beauty-sc-block-image mntl-sc-block-image figure-square figure-high-res\">\n<div class=\"figure-media\">\n<div class=\"img-placeholder\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" alt=\"Naturally curly hair before and after a Brazilian blowout treatment\" class=\"lazyload mntl-image mntl-image universal-image__image\" id=\"mntl-sc-block-image_2-0\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b.webp\" title=\"448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b.webp\" width=\"1024\" height=\"1024\" class=\"img--noscript mntl-image mntl-image universal-image__image\" alt=\"Naturally curly hair before and after a Brazilian blowout treatment\" title=\"448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b\"><\/div>\n<\/div><figcaption id=\"mntl-figure-caption_2-0\" class=\"comp mntl-figure-caption text-utility-100 figure-article-caption\"><span class=\"figure-article-caption-owner\"><\/p>\n<p>@brazilianblowout\/Instagram<\/p>\n<p><\/span><\/figcaption><\/figure>\n<h3 id=\"mntl-sc-block_33-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> What to Expect <\/span><\/h3>\n<p id=\"mntl-sc-block_34-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowout appointments typically last between two and four hours (depending on the length and thickness of your hair), and always begin with a consultation. \u201cThe client will first share their desired results with their stylist and discuss potential customization with heat styling,\u201d says Josh.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_36-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Then, the stylist will wash and towel dry the hair before applying the treatment from roots to end. \u201cBecause this treatment does not have any processing time, the stylist will then blow dry the hair with the applied treatment, typically using a round boar brush to style the hair,\u201d says Josh.\n<\/p>\n<h3 id=\"mntl-sc-block_38-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Best Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_39-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Anyone who wants smoother, straighter hair can benefit from this treatment. Keep in mind that Brazilian blowouts leave your hair pin-straight with little volume or texture. If you\u2019re looking to maintain some body or volume, you may want to opt for a standard keratin treatment instead.\n<\/p>\n<h3 id=\"mntl-sc-block_41-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Not Ideal Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_42-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> If your hair is already silky smooth, spare your hair from the chemicals and skip this treatment. And, again, if you\u2019re looking to decrease frizz but still want some texture, a Brazilian blowout isn\u2019t for you.<\/p>\n<h3 id=\"mntl-sc-block_44-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Typical Cost <\/span><\/h3>\n<p id=\"mntl-sc-block_45-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowouts can cost anywhere between $95 to $400. However, experts say the average price rounds out to $300.<\/p>\n<h2 id=\"mntl-sc-block_47-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> What to Consider <\/span><\/h2>\n<p id=\"mntl-sc-block_48-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> When trying to choose between these two hair treatments there are two main factors to consider\u2014hair texture and your desired result.\n<\/p>\n<h3 id=\"mntl-sc-block_50-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Hair Texture <\/span><\/h3>\n<p id=\"mntl-sc-block_51-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> \u201cThe biggest thing to consider here is your hair type,\u201d says Giarrizzo. \u201cBoth treatments are semi-permanent and can help improve your hair&#8217;s texture. Keratin treatments are best for people with wavy hair and Brazilian blowouts are better for people with dry or frizzy hair. Depending on what kind of hair you have, the results will be better if you do the treatment that works best for you.\u201d<\/p>\n<h3 id=\"mntl-sc-block_53-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Desired Results <\/span><\/h3>\n<p id=\"mntl-sc-block_54-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Though these two treatments are similar in a lot of ways, they can leave you with totally different results. \u201cA Brazilian blowout is designed to help defrizz hair and give it a straighter texture,\u201d says Josh. \u201cA keratin treatment is similar in that it defrizzes hair and cuts down on styling time, but it gives hair more of a looser body wave.\u201d<\/p>\n<h2 id=\"mntl-sc-block_56-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Potential Risks <\/span><\/h2>\n<p id=\"mntl-sc-block_57-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The biggest risks associated with keratin treatments come during the application process. \u201cSome keratin treatment formulas may contain formaldehyde, a strong-smelling chemical that can cause watery eyes, coughing, wheezing, skin irritation and a burning sensation in your eyes, nose and throat,\u201d says Combs. Even if a formula is formaldehyde-free, Giarrizzo cautions that keratin treatments tend to have a strong odor and may cause watery eyes and tingling on the scalp during treatment.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_59-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The other thing to keep in mind is that any sort of straightening treatment\u2014including these two\u2014may permanently mess with your curl pattern. If that\u2019s an issue for you, you\u2019ll likely want to explore other options.\n<\/p>\n<h2 id=\"mntl-sc-block_61-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Aftercare <\/span><\/h2>\n<p id=\"mntl-sc-block_62-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The aftercare for both keratin treatments and Brazilian blowouts is fairly simple. You\u2019ll want to wait for three days (or more!) to wash your hair and avoid touching it at all in the first 24 hours after the appointment.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_64-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> From there, stick with sulfate- and sodium chloride-free shampoos to extend the life of the treatment. Also, remember to turn down the temperatures on your styling tools as \u201chigh heat settings should be avoided on keratin-treated hair,\u201d says Combs. The good news is that keratin might just solve your need for hot tools\u2014and even if it doesn\u2019t, you\u2019ll be able to get better results from lower heat settings than you could pre-treatment.\n<\/p>\n<p id=\"mntl-sc-block_66-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> As time goes on, try to limit your washes as much as possible, and steer clear of chlorine. \u201cUsing products with keratin or things like silk pillowcases can also help to lengthen the results,\u201d says Giarrizzo.\u00a0\n<\/p>\n<h2 id=\"mntl-sc-block_68-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Final Takeaways <\/span><\/h2>\n<p id=\"mntl-sc-block_69-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are plenty of different ways for you to smooth out your strands, and both of these treatments offer results that make them worth their hefty price tags. For a straighter look with a little bit of body, opt for keratin; and for stick shiny strands, go for a Brazilian blowout.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"loc

Blowouts provide straight, sleek hair using an amino acid formula that avoids formaldehyde.<\/li>\n<li>Both treatments require proper aftercare, including avoiding washing hair for several days and

wanted smooth hair had to <em>literally<\/em> iron it out. Now there are tools and technologies specifically designed to straighten strands instantly. Among the most popular? Semi-permanent salon-grade treatments that leave hair smooth with zero effort on your part.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_4-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The two biggies, of course, are keratin treatments and Brazilian blowouts. Both of these treatments are lauded for their ability to reduce frizz and can deliver jaw-dropping results. But though they may offer similar effects, they\u2019re two entirely different treatments. Understanding how they work (and who they&#8217;re best for) is critical for choosing which one\u2019s best for you.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_6-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> \u201cBoth treatments are great for smoothing, but the main difference is what kind of results they can give,\u201d says Christina Giarrizzo, a celebrity hairstylist at Voel Hair in New York City. \u201cA Brazilian blowout will eliminate frizz and even straighten curly hair, while keratin will make your hair straighter and more manageable without damaging the integrity of the hair\u2019s structure.\u201d\u00a0\n<\/p>\n<p id=\"mntl-sc-block_8-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> So, which one will give you the smoothed-out strands of your dreams?

Additionally, this treatment can also be helpful for those who have thicker or more coarse textures and are looking to make their hair more manageable.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_18-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> That said, \u201cThe best person to determine if your hair is suitable for a keratin treatment is a licensed, professional salon stylist,\u201d says Combs. \u201cThe first step to receiving a keratin treatment is to schedule a consultation with your stylist. During the consultation, your stylist will ask questions to help determine which treatment is best suited for your hair type and hair goals.\u201d<\/p>\n<h3 id=\"mntl-sc-block_20-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Not Ideal Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_21-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> If you already have very thin, fragile hair, this treatment isn&#8217;t for you. It even can cause more damage than good. \u201cBecause keratin is designed to help thicker and coarse hair more manageable, it&#8217;s not ideal for people with superfine hair or those prone to breakage,&#8221; says Giarrizzo. &#8220;Especially considering the high heat of the flat iron used.&#8221;\n<\/p>\n<h3 id=\"mntl-sc-block_23-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Typical Cost <\/span><\/h3>\n<p id=\"mntl-sc-block_24-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The average keratin treatment costs between $200 and $800. \u201cThe price shifts based on several factors, including the length and density of a client\u2019s hair, the amount of time the application takes, and the formula longevity, which can span from 10 weeks to five months,\u201d says Combs.<\/p>\n<h3 id=\"mntl-sc-block_26-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> How Long Does it Last? <\/span><\/h3>\n<p id=\"mntl-sc-block_27-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> A keratin treatment lasts between four weeks and five months, depending on the formula that was used and how well you\u2019re caring for your hair.\n<\/p>\n<h2 id=\"mntl-sc-block_29-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> What Is a Brazilian Blowout? <\/span><\/h2>\n<p id=\"mntl-sc-block_30-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowouts are a type of keratin treatment that takes things one step further to smooth and straighten strands.\u00a0This treatment uses a proprietary blend of amino acids and proteins (including keratin) and is devoid of the formaldehyde that\u2019s often found in keratin treatments. \u201cA Brazilian blowout uses a liquid keratin formula that creates a layer over each strand of hair, and is sealed in with heat, to help straighten and smooth hair,\u201d says Harry Josh, a celebrity hairstylist and Kerasilk ambassador. Unlike keratin treatments, which are fairly \u201cone size fits all,\u201d Brazilian blowouts can be customized depending on the texture you\u2019re trying to achieve.<\/p>\n<figure id=\"mntl-sc-block_32-0\" class=\"comp mntl-sc-block beauty-sc-block-image mntl-sc-block-image figure-square figure-high-res\">\n<div class=\"figure-media\">\n<div class=\"img-placeholder\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" alt=\"Naturally curly hair before and after a Brazilian blowout treatment\" class=\"lazyload mntl-image mntl-image universal-image__image\" id=\"mntl-sc-block-image_2-0\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b.webp\" title=\"448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b.webp\" width=\"1024\" height=\"1024\" class=\"img--noscript mntl-image mntl-image universal-image__image\" alt=\"Naturally curly hair before and after a Brazilian blowout treatment\" title=\"448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b\"><\/div>\n<\/div><figcaption id=\"mntl-figure-caption_2-0\" class=\"comp mntl-figure-caption text-utility-100 figure-article-caption\"><span class=\"figure-article-caption-owner\"><\/p>\n<p>@brazilianblowout\/Instagram<\/p>\n<p><\/span><\/figcaption><\/figure>\n<h3 id=\"mntl-sc-block_33-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> What to Expect <\/span><\/h3>\n<p id=\"mntl-sc-block_34-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowout appointments typically last between two and four hours (depending on the length and thickness of your hair), and always begin with a consultation. \u201cThe client will first share their desired results with their stylist and discuss potential customization with heat styling,\u201d says Josh.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_36-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Then, the stylist will wash and towel dry the hair before applying the treatment from roots to end. \u201cBecause this treatment does not have any processing time, the stylist will then blow dry the hair with the applied treatment, typically using a round boar brush to style the hair,\u201d says Josh.\n<\/p>\n<h3 id=\"mntl-sc-block_38-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Best Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_39-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Anyone who wants smoother, straighter hair can benefit from this treatment. Keep in mind that Brazilian blowouts leave your hair pin-straight with little volume or texture. If you\u2019re looking to maintain some body or volume, you may want to opt for a standard keratin treatment instead.\n<\/p>\n<h3 id=\"mntl-sc-block_41-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Not Ideal Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_42-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> If your hair is already silky smooth, spare your hair from the chemicals and skip this treatment. And, again, if you\u2019re looking to decrease frizz but still want some texture, a Brazilian blowout isn\u2019t for you.<\/p>\n<h3 id=\"mntl-sc-block_44-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Typical Cost <\/span><\/h3>\n<p id=\"mntl-sc-block_45-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowouts can cost anywhere between $95 to $400. However, experts say the average price rounds out to $300.<\/p>\n<h2 id=\"mntl-sc-block_47-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> What to Consider <\/span><\/h2>\n<p id=\"mntl-sc-block_48-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> When trying to choose between these two hair treatments there are two main factors to consider\u2014hair texture and your desired result.\n<\/p>\n<h3 id=\"mntl-sc-block_50-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Hair Texture <\/span><\/h3>\n<p id=\"mntl-sc-block_51-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> \u201cThe biggest thing to consider here is your hair type,\u201d says Giarrizzo. \u201cBoth treatments are semi-permanent and can help improve your hair&#8217;s texture. Keratin treatments are best for people with wavy hair and Brazilian blowouts are better for people with dry or frizzy hair. Depending on what kind of hair you have, the results will be better if you do the treatment that works best for you.\u201d<\/p>\n<h3 id=\"mntl-sc-block_53-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Desired Results <\/span><\/h3>\n<p id=\"mntl-sc-block_54-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Though these two treatments are similar in a lot of ways, they can leave you with totally different results. \u201cA Brazilian blowout is designed to help defrizz hair and give it a straighter texture,\u201d says Josh. \u201cA keratin treatment is similar in that it defrizzes hair and cuts down on styling time, but it gives hair more of a looser body wave.\u201d<\/p>\n<h2 id=\"mntl-sc-block_56-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Potential Risks <\/span><\/h2>\n<p id=\"mntl-sc-block_57-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The biggest risks associated with keratin treatments come during the application process. \u201cSome keratin treatment formulas may contain formaldehyde, a strong-smelling chemical that can cause watery eyes, coughing, wheezing, skin irritation and a burning sensation in your eyes, nose and throat,\u201d says Combs. Even if a formula is formaldehyde-free, Giarrizzo cautions that keratin treatments tend to have a strong odor and may cause watery eyes and tingling on the scalp during treatment.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_59-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The other thing to keep in mind is that any sort of straightening treatment\u2014including these two\u2014may permanently mess with your curl pattern. If that\u2019s an issue for you, you\u2019ll likely want to explore other options.\n<\/p>\n<h2 id=\"mntl-sc-block_61-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Aftercare <\/span><\/h2>\n<p id=\"mntl-sc-block_62-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The aftercare for both keratin treatments and Brazilian blowouts is fairly simple. You\u2019ll want to wait for three days (or more!) to wash your hair and avoid touching it at all in the first 24 hours after the appointment.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_64-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> From there, stick with sulfate- and sodium chloride-free shampoos to extend the life of the treatment. Also, remember to turn down the temperatures on your styling tools as \u201chigh heat settings should be avoided on keratin-treated hair,\u201d says Combs. The good news is that keratin might just solve your need for hot tools\u2014and even if it doesn\u2019t, you\u2019ll be able to get better results from lower heat settings than you could pre-treatment.\n<\/p>\n<p id=\"mntl-sc-block_66-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> As time goes on, try to limit your washes as much as possible, and steer clear of chlorine. \u201cUsing products with keratin or things like silk pillowcases can also help to lengthen the results,\u201d says Giarrizzo.\u00a0\n<\/p>\n<h2 id=\"mntl-sc-block_68-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Final Takeaways <\/span><\/h2>\n<p id=\"mntl-sc-block_69-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are plenty of different ways for you to smooth out your strands, and both of these treatments offer results that make them worth their hefty price tags. For a straighter look with a little bit of body, opt for keratin; and for stick shiny strands, go for a Brazilian blowout.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"loc article-post-content\">\n<div id=\"beauty-breadcrumbs--chips_1-0\" class=\"comp beauty-breadcrumbs--chips mntl-universal-breadcrumbs--chips mntl-block\">\n<div id=\"mntl-breadcrumbs__read-more_1-0\" class=\"comp mntl-breadcrumbs__read-more mntl-text-block text-title-100\">Read more:<\/div>\n<ul id=\"mntl-universal-breadcrumbs_1-0\" class=\"comp mntl-universal-breadcrumbs mntl-block text-label-300 breadcrumbs\" data-tracking-container=\"true\">\n<li id=\"mntl-breadcrumbs__item_1-0\" class=\"comp mntl-breadcrumbs__item mntl-block\"><span class=\"link__wrapper\">Hair<\/span><\/li>\n<li id=\"mntl-breadcrumbs__item_2-0\" class=\"comp mntl-breadcrumbs__item mntl-block\"><span class=\"link__wrapper\">Hair Styling<\/span><\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/article>\n<div class=\"loc article-content\">\n<div id=\"article__broad-video-jw_1-0\" class=\"comp article__broad-video-jw mntl-jwplayer-broad mntl-block is-hidden\" data-pixel-depth=\"100\">\n<div id=\"mntl-jwplayer-broad__title_1-0\" class=\"comp mntl-jwplayer-broad__title mntl-block\"><button id=\"mntl-jwplayer-broad__title-icon--close_1-0\" class=\"comp mntl-jwplayer-broad__title-icon--close mntl-block text-label-100\" data-click-tracked=\"false\"><span id=\"mntl-text-block_2-0\" class=\"comp mntl-text-block\">Close<\/span><\/button><\/div>\n<\/div>\n<div id=\"mntl-block_2-0\" class=\"comp mntl-block article__body right-rail\">\n<figure id=\"mntl-universal-primary-image_1-0\" class=\"comp mntl-universal-primary-image primary-image\" data-tracking-container=\"true\">\n<div class=\"primary-image__media\">\n<div class=\"img-placeholder\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/jaslede-62f4c12bf87c4edc8d60bf28251bc0e6-8.webp\" width=\"2000\" height=\"1500\" alt=\"Jasmine Tookes with her hair sleek and shiny.\" class=\" primary-image__image mntl-primary-image--blurry\" title=\"jaslede-62f4c12bf87c4edc8d60bf28251bc0e6-8\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/jaslede-62f4c12bf87c4edc8d60bf28251bc0e6-8.webp\" width=\"2000\" height=\"1500\" class=\"loaded primary-img--noscript primary-image__image mntl-primary-image--blurry\" alt=\"Jasmine Tookes with her hair sleek and shiny.\" title=\"jaslede-62f4c12bf87c4edc8d60bf28251bc0e6-8\"><\/div>\n<\/div><figcaption id=\"primary-image__figcap_1-0\" class=\"comp primary-image__figcap mntl-figure-caption figure-article-caption\"><span class=\"figure-article-caption-owner\"><\/p>\n<p>@jastookes\/Instagram<\/p>\n<p><\/span><\/figcaption><\/figure>\n<div id=\"mntl-sc-page_1-0\" class=\"comp mntl-sc-page mntl-block\" data-sc-sticky-offset=\"125\" data-sc-ad-label-height=\"16\" data-sc-ad-track-spacing=\"100\" data-sc-min-track-height=\"250\" data-sc-max-track-height=\"600\" data-sc-breakpoint=\"50em\" data-sc-load-immediate=\"5\" data-sc-content-positions=\"[1, 1250, 1, 1, 1, 1, 1, 1, 1]\" data-bind-scroll-on-start=\"true\">\n<div id=\"mntl-sc-block_1-0\" class=\"comp mntl-sc-block beauty-sc-block-callout--finalverdict beauty-sc-block-callout mntl-sc-block-callout mntl-block theme-finalverdict\" data-tracking-id=\"mntl-sc-block-callout\" data-tracking-container=\"true\">\n<p id=\"mntl-sc-block-callout-heading_1-0\" class=\"comp mntl-sc-block-callout-heading mntl-text-block\">Key Takeaways<\/p>\n<div id=\"mntl-sc-block-callout-body_1-0\" class=\"comp mntl-sc-block-callout-body mntl-text-block\">\n<ul>\n<li>Keratin treatments make thick or frizzy hair smoother and more manageable without affecting its natural structure.<\/li>\n<li>Brazilian Blowouts provide straight, sleek hair using an amino acid formula that avoids formaldehyde.<\/li>\n<li>Both treatments require proper aftercare, including avoiding washing hair for several days and using sulfate-free shampoos.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p id=\"mntl-sc-block_2-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There was once a time when those who wanted smooth hair had to <em>literally<\/em> iron it out.

During the consultation, your stylist will ask questions to help determine which treatment is best suited for your hair type and hair goals.\u201d<\/p>\n<h3 id=\"mntl-sc-block_20-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Not Ideal Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_21-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> If you already have very thin, fragile hair, this treatment isn&#8217;t for you.

Unlike keratin treatments, which are fairly \u201cone size fits all,\u201d Brazilian blowouts can be customized depending on the texture you\u2019re trying to achieve.<\/p>\n<figure id=\"mntl-sc-block_32-0\" class=\"comp mntl-sc-block beauty-sc-block-image mntl-sc-block-image figure-square figure-high-res\">\n<div class=\"figure-media\">\n<div class=\"img-placeholder\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" alt=\"Naturally curly hair before and after a Brazilian blowout treatment\" class=\"lazyload mntl-image mntl-image universal-image__image\" id=\"mntl-sc-block-image_2-0\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b.webp\" title=\"448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b.webp\" width=\"1024\" height=\"1024\" class=\"img--noscript mntl-image mntl-image universal-image__image\" alt=\"Naturally curly hair before and after a Brazilian blowout treatment\" title=\"448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b\"><\/div>\n<\/div><figcaption id=\"mntl-figure-caption_2-0\" class=\"comp mntl-figure-caption text-utility-100 figure-article-caption\"><span class=\"figure-article-caption-owner\"><\/p>\n<p>@brazilianblowout\/Instagram<\/p>\n<p><\/span><\/figcaption><\/figure>\n<h3 id=\"mntl-sc-block_33-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> What to Expect <\/span><\/h3>\n<p id=\"mntl-sc-block_34-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowout appointments typically last between two and four hours (depending on the length and thickness of your hair), and always begin with a consultation. \u201cThe client will first share their desired results with their stylist and discuss potential customization with heat styling,\u201d says Josh.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_36-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Then, the stylist will wash and towel dry the hair before applying the treatment from roots to end. \u201cBecause this treatment does not have any processing time, the stylist will then blow dry the hair with the applied treatment, typically using a round boar brush to style the hair,\u201d says Josh.\n<\/p>\n<h3 id=\"mntl-sc-block_38-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Best Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_39-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Anyone who wants smoother, straighter hair can benefit from this treatment. Keep in mind that Brazilian blowouts leave your hair pin-straight with little volume or texture. If you\u2019re looking to maintain some body or volume, you may want to opt for a standard keratin treatment instead.\n<\/p>\n<h3 id=\"mntl-sc-block_41-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Not Ideal Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_42-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> If your hair is already silky smooth, spare your hair from the chemicals and skip this treatment. And, again, if you\u2019re looking to decrease frizz but still want some texture, a Brazilian blowout isn\u2019t for you.<\/p>\n<h3 id=\"mntl-sc-block_44-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Typical Cost <\/span><\/h3>\n<p id=\"mntl-sc-block_45-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowouts can cost anywhere between $95 to $400. However, experts say the average price rounds out to $300.<\/p>\n<h2 id=\"mntl-sc-block_47-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> What to Consider <\/span><\/h2>\n<p id=\"mntl-sc-block_48-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> When trying to choose between these two hair treatments there are two main factors to consider\u2014hair texture and your desired result.\n<\/p>\n<h3 id=\"mntl-sc-block_50-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Hair Texture <\/span><\/h3>\n<p id=\"mntl-sc-block_51-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> \u201cThe biggest thing to consider here is your hair type,\u201d says Giarrizzo. \u201cBoth treatments are semi-permanent and can help improve your hair&#8217;s texture. Keratin treatments are best for people with wavy hair and Brazilian blowouts are better for people with dry or frizzy hair. Depending on what kind of hair you have, the results will be better if you do the treatment that works best for you.\u201d<\/p>\n<h3 id=\"mntl-sc-block_53-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Desired Results <\/span><\/h3>\n<p id=\"mntl-sc-block_54-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Though these two treatments are similar in a lot of ways, they can leave you with totally different results. \u201cA Brazilian blowout is designed to help defrizz hair and give it a straighter texture,\u201d says Josh. \u201cA keratin treatment is similar in that it defrizzes hair and cuts down on styling time, but it gives hair more of a looser body wave.\u201d<\/p>\n<h2 id=\"mntl-sc-block_56-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Potential Risks <\/span><\/h2>\n<p id=\"mntl-sc-block_57-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The biggest risks associated with keratin treatments come during the application process. \u201cSome keratin treatment formulas may contain formaldehyde, a strong-smelling chemical that can cause watery eyes, coughing, wheezing, skin irritation and a burning sensation in your eyes, nose and throat,\u201d says Combs. Even if a formula is formaldehyde-free, Giarrizzo cautions that keratin treatments tend to have a strong odor and may cause watery eyes and tingling on the scalp during treatment.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_59-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The other thing to keep in mind is that any sort of straightening treatment\u2014including these two\u2014may permanently mess with your curl pattern. If that\u2019s an issue for you, you\u2019ll likely want to explore other options.\n<\/p>\n<h2 id=\"mntl-sc-block_61-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Aftercare <\/span><\/h2>\n<p id=\"mntl-sc-block_62-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The aftercare for both keratin treatments and Brazilian blowouts is fairly simple. You\u2019ll want to wait for three days (or more!) to wash your hair and avoid touching it at all in the first 24 hours after the appointment.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_64-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> From there, stick with sulfate- and sodium chloride-free shampoos to extend the life of the treatment. Also, remember to turn down the temperatures on your styling tools as \u201chigh heat settings should be avoided on keratin-treated hair,\u201d says Combs. The good news is that keratin might just solve your need for hot tools\u2014and even if it doesn\u2019t, you\u2019ll be able to get better results from lower heat settings than you could pre-treatment.\n<\/p>\n<p id=\"mntl-sc-block_66-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> As time goes on, try to limit your washes as much as possible, and steer clear of chlorine. \u201cUsing products with keratin or things like silk pillowcases can also help to lengthen the results,\u201d says Giarrizzo.\u00a0\n<\/p>\n<h2 id=\"mntl-sc-block_68-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Final Takeaways <\/span><\/h2>\n<p id=\"mntl-sc-block_69-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are plenty of different ways for you to smooth out your strands, and both of these treatments offer results that make them worth their hefty price tags. For a straighter look with a little bit of body, opt for keratin; and for stick shiny strands, go for a Brazilian blowout.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div id=\"mntl-sc-page_1-0\" class=\"comp mntl-sc-page mntl-block\" data-sc-sticky-offset=\"125\" data-sc-ad-label-height=\"16\" data-sc-ad-track-spacing=\"100\" data-sc-min-track-height=\"250\" data-sc-max-track-height=\"600\" data-sc-breakpoint=\"50em\" data-sc-load-immediate=\"5\" data-sc-content-positions=\"[1, 1250, 1, 1, 1, 1, 1, 1, 1]\" data-bind-scroll-on-start=\"true\">\n<div id=\"mntl-sc-block_1-0\" class=\"comp mntl-sc-block beauty-sc-block-callout--finalverdict beauty-sc-block-callout mntl-sc-block-callout mntl-block theme-finalverdict\" data-tracking-id=\"mntl-sc-block-callout\" data-tracking-container=\"true\">\n<p id=\"mntl-sc-block-callout-heading_1-0\" class=\"comp mntl-sc-block-callout-heading mntl-text-block\">Key Takeaways<\/p>\n<div id=\"mntl-sc-block-callout-body_1-0\" class=\"comp mntl-sc-block-callout-body mntl-text-block\">\n<ul>\n<li>Keratin treatments make thick or frizzy hair smoother and more manageable without affecting its natural structure.<\/li>\n<li>Brazilian Blowouts provide straight, sleek hair using an amino acid formula that avoids formaldehyde.<\/li>\n<li>Both treatments require proper aftercare, including avoiding washing hair for several days and using sulfate-free shampoos.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p id=\"mntl-sc-block_2-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There was once a time when those who wanted smooth hair had to <em>literally<\/em> iron it out.

Semi-permanent salon-grade treatments that leave hair smooth with zero effort on your part.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_4-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The two biggies, of course, are keratin treatments and Brazilian blowouts. Both of these treatments are lauded for their ability to reduce frizz and can deliver jaw-dropping results. But though they may offer similar effects, they\u2019re two entirely different treatments. Understanding how they work (and who they&#8217;re best for) is critical for choosing which one\u2019s best for you.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_6-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> \u201cBoth treatments are great for smoothing, but the main difference is what kind of results they can give,\u201d says Christina Giarrizzo, a celebrity hairstylist at Voel Hair in New York City. \u201cA Brazilian blowout will eliminate frizz and even straighten curly hair, while keratin will make your hair straighter and more manageable without damaging the integrity of the hair\u2019s structure.\u201d\u00a0\n<\/p>\n<p id=\"mntl-sc-block_8-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> So, which one will give you the smoothed-out strands of your dreams?

Unlike keratin treatments, which are fairly \u201cone size fits all,\u201d Brazilian blowouts can be customized depending on the texture you\u2019re trying to achieve.<\/p>\n<figure id=\"mntl-sc-block_32-0\" class=\"comp mntl-sc-block beauty-sc-block-image mntl-sc-block-image figure-square figure-high-res\">\n<div class=\"figure-media\">\n<div class=\"img-placeholder\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" alt=\"Naturally curly hair before and after a Brazilian blowout treatment\" class=\"lazyload mntl-image mntl-image universal-image__image\" id=\"mntl-sc-block-image_2-0\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b.webp\" title=\"448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/analyse.optim.biz\/wp-content\/uploads\/2026\/02\/448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b.webp\" width=\"1024\" height=\"1024\" class=\"img--noscript mntl-image mntl-image universal-image__image\" alt=\"Naturally curly hair before and after a Brazilian blowout treatment\" title=\"448523787_18437725726018038_8189364269088064558_n-847db9952d7d4ff1a18a5285ec6c362b\"><\/div>\n<\/div><figcaption id=\"mntl-figure-caption_2-0\" class=\"comp mntl-figure-caption text-utility-100 figure-article-caption\"><span class=\"figure-article-caption-owner\"><\/p>\n<p>@brazilianblowout\/Instagram<\/p>\n<p><\/span><\/figcaption><\/figure>\n<h3 id=\"mntl-sc-block_33-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> What to Expect <\/span><\/h3>\n<p id=\"mntl-sc-block_34-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowout appointments typically last between two and four hours (depending on the length and thickness of your hair), and always begin with a consultation. \u201cThe client will first share their desired results with their stylist and discuss potential customization with heat styling,\u201d says Josh.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_36-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Then, the stylist will wash and towel dry the hair before applying the treatment from roots to end. \u201cBecause this treatment does not have any processing time, the stylist will then blow dry the hair with the applied treatment, typically using a round boar brush to style the hair,\u201d says Josh.\n<\/p>\n<h3 id=\"mntl-sc-block_38-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Best Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_39-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Anyone who wants smoother, straighter hair can benefit from this treatment. Keep in mind that Brazilian blowouts leave your hair pin-straight with little volume or texture. If you\u2019re looking to maintain some body or volume, you may want to opt for a standard keratin treatment instead.\n<\/p>\n<h3 id=\"mntl-sc-block_41-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Not Ideal Candidates <\/span><\/h3>\n<p id=\"mntl-sc-block_42-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> If your hair is already silky smooth, spare your hair from the chemicals and skip this treatment. And, again, if you\u2019re looking to decrease frizz but still want some texture, a Brazilian blowout isn\u2019t for you.<\/p>\n<h3 id=\"mntl-sc-block_44-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Typical Cost <\/span><\/h3>\n<p id=\"mntl-sc-block_45-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Brazilian blowouts can cost anywhere between $95 to $400. However, experts say the average price rounds out to $300.<\/p>\n<h2 id=\"mntl-sc-block_47-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> What to Consider <\/span><\/h2>\n<p id=\"mntl-sc-block_48-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> When trying to choose between these two hair treatments there are two main factors to consider\u2014hair texture and your desired result.\n<\/p>\n<h3 id=\"mntl-sc-block_50-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Hair Texture <\/span><\/h3>\n<p id=\"mntl-sc-block_51-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> \u201cThe biggest thing to consider here is your hair type,\u201d says Giarrizzo. \u201cBoth treatments are semi-permanent and can help improve your hair&#8217;s texture. Keratin treatments are best for people with wavy hair and Brazilian blowouts are better for people with dry or frizzy hair. Depending on what kind of hair you have, the results will be better if you do the treatment that works best for you.\u201d<\/p>\n<h3 id=\"mntl-sc-block_53-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Desired Results <\/span><\/h3>\n<p id=\"mntl-sc-block_54-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Though these two treatments are similar in a lot of ways, they can leave you with totally different results. \u201cA Brazilian blowout is designed to help defrizz hair and give it a straighter texture,\u201d says Josh. \u201cA keratin treatment is similar in that it defrizzes hair and cuts down on styling time, but it gives hair more of a looser body wave.\u201d<\/p>\n<h2 id=\"mntl-sc-block_56-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Potential Risks <\/span><\/h2>\n<p id=\"mntl-sc-block_57-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The biggest risks associated with keratin treatments come during the application process. \u201cSome keratin treatment formulas may contain formaldehyde, a strong-smelling chemical that can cause watery eyes, coughing, wheezing, skin irritation and a burning sensation in your eyes, nose and throat,\u201d says Combs. Even if a formula is formaldehyde-free, Giarrizzo cautions that keratin treatments tend to have a strong odor and may cause watery eyes and tingling on the scalp during treatment.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_59-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The other thing to keep in mind is that any sort of straightening treatment\u2014including these two\u2014may permanently mess with your curl pattern. If that\u2019s an issue for you, you\u2019ll likely want to explore other options.\n<\/p>\n<h2 id=\"mntl-sc-block_61-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Aftercare <\/span><\/h2>\n<p id=\"mntl-sc-block_62-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The aftercare for both keratin treatments and Brazilian blowouts is fairly simple. You\u2019ll want to wait for three days (or more!) to wash your hair and avoid touching it at all in the first 24 hours after the appointment.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_64-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> From there, stick with sulfate- and sodium chloride-free shampoos to extend the life of the treatment. Also, remember to turn down the temperatures on your styling tools as \u201chigh heat settings should be avoided on keratin-treated hair,\u201d says Combs. The good news is that keratin might just solve your need for hot tools\u2014and even if it doesn\u2019t, you\u2019ll be able to get better results from lower heat settings than you could pre-treatment.\n<\/p>\n<p id=\"mntl-sc-block_66-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> As time goes on, try to limit your washes as much as possible, and steer clear of chlorine. \u201cUsing products with keratin or things like silk pillowcases can also help to lengthen the results,\u201d says Giarrizzo.\u00a0\n<\/p>\n<h2 id=\"mntl-sc-block_68-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Final Takeaways <\/span><\/h2>\n<p id=\"mntl-sc-block_69-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are plenty of different ways for you to smooth out your strands, and both of these treatments offer results that make them worth their hefty price tags. For a straighter look with a little bit of body, opt for keratin; and for stick shiny strands, go for a Brazilian blowout.<\/p>\n<\/div>\n<p> Source URL: https:\/\/www.byrdie.com\/keratin-treatments-vs-brazilian-blowouts-11890402<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What&#8217;s the Difference Between a Keratin Treatment and a Brazilian Blowout?
