    From aisles of styling products to overloaded shampoo shelves, hair care is becoming more and more personalized. Purchasing any product without knowing your hair type and its very specific needs seems like an ancient convenience, now replaced with so many choices we get decision paralysis just thinking about them. Narrowing down your hair type can be tricky, even with all the charts, graphs, and quizzes available. Deciding if you have fine hair vs. thin hair (and how to care for your hair type accordingly) is one hurdle many struggle with, especially when so many options clearly distinguish between one or the other.\n<\/p>\n

    The confusing caveat? \u201cIn the dermatology world, we use the words fine hair and thin hair interchangeably,\u201d says Helena Kuhn, MD, assistant professor of dermatology at Brown University. \u201cDifferent ethnicities have a different size and shape of the hair follicle, accounting for the different hair types seen throughout various populations.\u201d\n<\/p>\n

    So is there really even a difference between the two? Ahead, Dr. Kuhn, along with board-certified dermatologist Nazanin Saedi, and celebrity hairstylist Andrew Fitzsimons explain the difference between fine hair vs. thin hair, plus the best ways to care for each hair type.\n<\/p>\n

    \n

    Meet the Experts<\/p>\n

    • Nazanin Saedi, MD, is a Philadelphia-based, board-certified dermatologist and Clinical Associate Professor at Thomas Jefferson University.<\/li>\n
    • Helena Kuhn, MD, is an assistant professor of dermatology at Brown University.\u00a0<\/li>\n

      What Is Fine Hair? <\/span><\/h2>\n

      \u201cFine hair means that the actual diameter <\/em>of your hair is thin,\u201d explains Dr. Saedi. So, what exactly does that translate to for your strands? \u201cFine or thin hair is the result of a small and narrow hair follicle that creates a thin hair shaft, leading to hair that looks and feels thin and in general does not have much volume,\u201d Dr. Kuhn says.\u00a0\u201cHair follicle shape and size is a genetically determined trait and we can\u2019t do much to change the thickness of the hair shaft, unfortunately.\u201d\n<\/p>\n

      What Is Thin Hair? <\/span><\/h2>\n

      \u201cThin<\/em> hair refers to the density\u2014i.e. the number of strands\u2014of the hair in a given area on your scalp,\u201d Dr. Saedi says. \u201cSo, it is the amount of hair on your scalp.\u201d To help you differentiate between fine hair vs. thin hair, Dr. Saedi explains that you can have fine hair but have a high density of hair to make it look thicker.\n<\/p>\n

      Thin Hair vs. Thinning Hair <\/span><\/h2>\n

      Since thinning hair refers to the loss of hair density on the scalp, this means existing hair follicles are becoming smaller, resulting in finer and sometimes shorter hair, and less hair overall. \u201cThinning hair is when you are losing hair and the density of hair on your scalp is getting less,\u201d Dr. Saedi says. \u201cPatients come who have thick hair but complain about it thinning\u2014it usually is not the individual hairs becoming thinner but losing the density, so there\u2019s fewer hairs on the scalp.\u201d While thin hair can be your baseline hair type, thinning hair is an active process where change and transformation can be seen and evaluated.<\/p>\n

      How to Tell If Your Hair Is Thinning <\/span><\/h2>\n

      One telltale sign of thinning hair is noticing your part has gotten wider and increased in size, or if you can wrap around your hair tie more times when you put it in a ponytail, says Dr. Saedi.<\/p>\n

      \u201cPeople with thinning hair start to notice a change from their baseline hair type, for example, that their ponytail is a lot thinner, or that they have a lot less hair when they are shampooing,\u201d Dr. Kuhn says. \u201cThe scalp also becomes more visible as the hair thinning occurs, which is often how patients begin to notice their hair thinning. Some people also notice an uptick in shedding. Shedding up to 150 hairs a day is normal, but when it becomes excessive, prolonged shedding is concerning.\u201d<\/p>\n

      Causes of Hair Thinning <\/span><\/h2>\n

      Hair Loss:<\/strong> Thinning hair is most often due to androgenetic alopecia, which is female pattern hair loss or male pattern hair loss. This loss is primarily due to age and genetics, and it\u2019s difficult to reduce your risk. Hair loss can be inherited from both sides of the family. \u201cThere is no cure yet, unfortunately, but with early and consistent treatment it can be reversed,\u201d Dr. Kuhn says.\n<\/p>\n

      Chronic Shedding:<\/strong> “Thinning can also result from chronic shedding, which in the medical world we refer to as \u2018telogen effluvium,\u2019” continues Dr. Kuhn. “There are a variety of causes for telogen effluvium,\u00a0which is generally understood as hair shedding in response to a stressor.\u201d With telogen effluvium, Dr. Kuhn explains that the actual hair shedding itself is often delayed three months after the stressor, and hair will then shed an additional three to six months. The stressor can be emotional stress (breakup, death of a loved one, severe depression or anxiety), or physical stress (like a traumatic accident or significant surgery), from rapid weight loss, medications (retinoids, beta blockers, calcium channel blockers, antidepressants, lithium), post-partum, iron deficiency, vitamin A excess, severe thyroid disease, or general anesthesia. \u201cThis type of hair loss is temporary and non-scarring, meaning once the stressor is resolved or removed, the shedding will stop and hair will regrow,\u201d she says.<\/p>\n

      Prolonged Tension:<\/strong> In Latinx and African-American populations, tight hairstyling can also lead to hair thinning. \u201cThis type of loss can be permanent, so these populations should seek treatment for hair loss as soon as possible,\u201d Dr. Kuhn says. \u201cThere are also many rare causes of hair loss due to inflammatory and autoimmune disorders that I see and treat in my clinic.\u201d If hair thinning persists, make an appointment with a dermatologist.\n<\/p>\n

      Styling Fine Hair <\/span><\/h2>\n

      To make the most of fine hair, it\u2019s all about learning to work with it and style it the right way. \u201cWith fine hair, you could have really, really thick hair density-wise, so you could still definitely have layers,\u201d says Fitzsimons. \u201cYou can have your hair more razor cut\u2014you don’t have to have it as straight across like when your hair is thinner. You want the baseline of your hair to look as thick as possible, so when your hair is fine, you can get away with more if you have a lot of it.\u201d\n<\/p>\n

      \u201cUse clarifying products and exfoliate the scalp semi-regularly to help stimulate the follicles and hair growth, and opt for shorter, more blunt cuts to give off a fuller look,\u201d Fitzsimons says.\n<\/p>\n

      Styling Thin Hair <\/span><\/h2>\n

      There’s no rule book that says you have to sport a certain style just because your hair is thin or thinning. Wear whatever style you feel suits you\u2014but if you’re in the market for a style that will create the appearance of fullness, you definitely have choices. “There are options when it comes to extensions for adding more hair or using products that will allow your hair to look fuller,” says Fitzsimons. “Generally, when it comes to haircuts, if your hair is thin, the shorter your hair then the fuller it will look.\u201d\u00a0\n<\/p>\n

      Many people with thinning hair use fibers or colored sprays to camouflage the scalp. \u201cThese are fine to use for special occasions or a couple times a week, but I strongly recommend not using these products daily as there is evidence that they can occlude hair follicles and worsen androgenetic alopecia,\u201d Dr. Kuhn warns.\u00a0<\/strong><\/p>\n

      Make sure to avoid heavy products on thin hair, which can weigh it down and make it even flatter. To add volume, Fitzsimons recommends cleansing the hair and scalp very well and using a lightweight conditioner. Volumizing sprays and mousses will help lift hair at the root.\n<\/p>\n

      \u201cUse formulas with keratin building ingredients to help promote the health of the hair shaft, and similar to thin hair, be sure to exfoliate the scalp often as product buildup can weigh the hair down, whereas the goal should be to make the hair look as full as possible,\u201d Fitzsimons says.\u00a0\u00a0<\/strong><\/p>\n

      The Final Takeaway <\/span><\/h2>\n

      When it comes to fine hair vs. thin hair, it\u2019s important to remember that there are differences between the two and they should be treated as such. Fine hair refers to the thickness\u2014or diameter\u2014of a single strand of hair. Meanwhile, thin hair refers to the actual volume\u2014or number of\u2014hair strands you have on your head.\n<\/p>\n

      All of our experts note that there are certain haircare factors to take into account when it comes to treating and styling your fine or thin hair. But our experts also agree they many people with average hair strand diameter and density think<\/em> they have thin hair because of unrealistic beauty standards.\n<\/p>\n

      \u201cHonestly, in haircare, only overly thick hair is ever advertised, a lot of the time to the point where it’s not realistic,\u201d Fitzsimons says.\u00a0\u201cVery, very, very few people on the planet have that amount of hair, so also it comes down to expectation. Often people will think they have to cut their hair because it appears thin. And I’ll say, \u2018no, your hair looks like the amount of hair that most people have.\u2019 It’s just that we’re bombarded with all of these unrealistic images all of the time.”\n<\/p>\n

      FAQ<\/div>\n
        \n
      • \n
        How do I know if my hair is fine?<\/span><\/div>\n
        \n
        \n
        \n

        Fine hair is made up of hair strands with a narrow diameter. It is important to note that this is not a reflection of actual hair density (the amount of hair you have). Fine hair looks and feels thin and usually has very little volume.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/li>\n

      • \n
        Is thin hair the same as fine hair?<\/span><\/div>\n
        \n
        \n
        \n

        Thin or thinning hair is characterized by a loss or lack of hair density on the scalp, meaning the amount of hair decreases. (People with very thick hair may also have thinning hair.) In contrast, fine hair refers to the thin diameter of each hair strand regardless of density.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n
