Biotin shampoo contains biotin, which is a type of B vitamin known for being good for the hair. This shampoo is often used by people who have problems with hair loss or who have very weak, unhealthy hair. While most people have adequate amounts of biotin in their systems, some people do occasionally become deficient in it as a result of taking certain medications or having various health problems. This deficiency can lead to hair loss, and people who are deficient in biotin may benefit from either taking biotin in supplement form or from using biotin shampoo.
It is possible that biotin might help with hair regrowth because it could strengthen the hair follicles, which promotes healthy hair growth. The hair shaft might also benefit from biotin, and when hair regrows it may be less likely to break off or split at the ends. When biotin shampoo is used, a person may notice that her hair appears fuller and thicker, which is likely a direct result of biotin's positive impact on the hair shaft. In spite of many claims to the contrary, this shampoo alone may not be enough to make a person's hair grow back if it has been falling out, though it may make existing hair stronger.
Biotin supplements could be helpful for a person who wants to regrow lost hair. There is no evidence that biotin shampoo alone can make hair grow because the biotin contained in the shampoo likely cannot penetrate the scalp. When a person takes biotin supplements, the nutrient is entering the body directly. If there is any benefit to be had from the use of biotin for hair regrowth, biotin supplements may be the best way for a person to take advantage of them. In addition to the hair, biotin may also improve the appearance of the skin and help boost a person's metabolism.
Even though biotin shampoo might not do much to help hair grow, many people may still benefit from using it because it could potentially improve the appearance of existing hair. The shampoo is available under many different brand names and is likely available for sale at the majority of health and beauty supply stores as well as online. If a person is experiencing excessive hair loss, he may need to see his doctor before using biotin shampoo or supplements. There is always a chance that hair loss may be related to a serious health problem requiring medical care.
