We have come a long way in our search for straight hair. While the first straightener was invented in 1909, there were days of using an ironing board to smooth out the frizz, and now we have pretty much any tool and product under the sun promising sleeker strands whenever we want. But if you\u2019re looking for a more permanent solution, a.k.a. a break from using a hot flat iron regularly, there\u2019s one chemical treatment you can turn to: Japanese hair straightening.<\/p>\n

Japanese hair straightening can be a solution to your styling woes if you want to cut your routine down and stick to one hairstyle for months on end. As a child of the early aughts and mid-2010s, I got this treatment twice a year, every year, up until I graduated college. Just as I was never stressed about what to wear to school thanks to a mandated uniform, rarely did I ever have to worry about how to style my already sleek and shiny hair. But Japanese hair straightening isn’t a one-size-fits-all treatment, and there are a couple of things you should know before making the a commitment. Because it is a pretty big one where hair is concerned.<\/p>\n

What is Japanese hair straightening?<\/h2>\n

New York City-based board-certified dermatologist Hadley King, MD, says Japanese hair straightening (also called thermal reconditioning) is a chemical hair treatment that restructures bonds in your hair strands to straighten and smooth them out. Dr. King explains that the process uses a combination of chemical solution and heat to break and reform the disulfide bonds in hair to permanently change the structure until your hair grows out.<\/p>\n

While it sounds similar to other chemical treatments, such as the Brazilian blowout or keratin-based treatments, it is different from the rest. Angela J. Lamb, MD, associate professor in the department of dermatology at Mount Sinai\u2019s Icahn School of Medicine, says that a Brazilian blowout and keratin treatment are not permanent solutions, with more flexibility in styling.<\/p>\n

\u201cThey\u2019re all smoothing treatments, but they work very differently,\u201d adds celebrity hairstylist Joseph Maine. \u201cJapanese straightening permanently changes the structure of the hair, and it\u2019s a full chemical process, not a coating. Brazilian blowouts and keratin treatments are semi-permanent; they smooth frizz and add shine, but they wash out over time and don\u2019t make the hair pin-straight.\u201d<\/p>\n

The Benefits<\/h2>\n

One of the biggest benefits of Japanese hair straightening, says Dr. Lamb, is that hair becomes permanently straight. She says that it provides easy styling to those who are looking for a consistently sleek, straight look. Maine agrees and adds that it will give you lasting shine and can be resistant to humidity and frizz.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Another added benefit is that Japanese hair straightening treatments typically don\u2019t use formaldehyde, as it uses different chemical agents to restructure bonds that other similar chemical stylers. (Though Maine emphasizes that it is still a strong chemical treatment, so you still want to be careful when deciding where to get it done.)<\/p>\n

This treatment is also best for those looking to keep hair consistently sleek and straight. Dr. Lamb says that if you have strong, healthy hair and have not gone through a lot of bleaching or other harsh chemical styling, this could be a good option for you. But if you\u2019re someone who wants to switch between straight and curly styles, Main says you may want to rethink this permanent solution.<\/p>\n

The Downsides<\/h2>\n

There are a few downsides to Japanese hair straightening that you should be aware of. Dr. King says the process may weaken or dry hair, especially if your hair is already in a fragile state or has been through other chemical treatments like hair dyeing or bleaching. The treatment is also expensive and time-consuming (more on that later), and it requires strict aftercare and touchups, so it\u2019s definitely worth asking yourself if you\u2019re up for this type of commitment. She adds that it limits what you can do to your hair in terms of styling, as it won\u2019t hold waves or curls.<\/p>\n

Japanese hair straightening is also not suitable for everyone. Maine says that very fine hair or any hair that has been heavily bleached or lightened should avoid such a strong chemical process. King agrees and adds that if your hair is already fragile from previous repeated chemical processing, it\u2019s best to opt out of this.<\/p>\n

The Treatment<\/h2>\n

Be warned: Japanese hair straightening is a long process. Experts say it can take many hours, depending on how much hair you have and how wavy or curly your natural hair is. You can expect your hair to be first washed with a clarifying shampoo before your stylist applies the chemical straightening solution.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Maine explains that the chemical solution used is meant to break down the hair\u2019s internal bonds to start the straightening process. It will sit on your hair to set (how long this takes will depend on how long and how wavy and curly your natural texture is) before being rinsed off. Your stylist will then blow-dry dry hair and flat-iron it in small sections, which he says is meant to set the new straight structure. Dr. King adds that a neutralizing solution will then be applied that will re-bond hair to lock everything in shape, followed by another rinse and styling session.<\/p>\n

Post-Care<\/h2>\n

Taking care of your hair after a treatment is pretty easy. Maine says that you should not tie, bend, or wash hair for at least 48 hours afterwards. Then it is recommended that you use gentle, sulfate-free shampoos.<\/p>\n

Dr. Lamb recommends avoiding excessive heat styling (use a heat protectant for the times that you do), and Maine adds that you\u2019ll also want to avoid overlapping other chemical treatments like bleaching or perming to keep hair healthy. You\u2019ll also want to consider incorporating a good hydrating mask or leave-in conditioner since the treatment might leave hair more porous or dry. And the last pro tip? \u201cRegular trims and conditioning treatments keep hair healthy and glossy,\u201d he says.<\/p>\n

How long do results last?<\/h2>\n

As mentioned before, Japanese hair straightening is permanent\u2014but only on the parts of hair that are treated. Main explains that when new hair grows in, it won\u2019t be as straight as the rest of your hair that has undergone permanent straightening. For that reason, it is recommended that people do touch-ups every six to 12 months, depending on how fast your hair grows or how noticeable the texture difference becomes.<\/p>\n

How much does this treatment cost?<\/h2>\n

Though it can depend on a variety of different factors, Japanese hair straightening in general can be pricey. \u201cIt varies based on salon, skill level, location, and hair length [or] thickness,\u201d says Maine. \u201cBut typically, [treatment] ranges anywhere from $400 to $800 [or more] because of the time and precision involved.\u201d<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

So if you have the means, patience, and\u2014most importantly\u2014a love for pin-straight hair, ask your stylist if this is something you should consider. Though I haven’t gone back to get my hair chemically straightened in over a decade, I do almost miss the ease of having my hair already set. What a simpler life it was.<\/p>\n
