Biotin is an essential B vitamin that is used to promote hair health and growth. Because biotin deficiency can lead to thinning hair, proponents say biotin supplements can help correct this problem, though it may be a few months to see results. Biotin is available in pill tablet & Softgel form. While biotin supplements may have benefits for some, there are also potential side effects that are worth considering before you start taking one. Using a biotin-containing hair product doesn't pose the same concerns, but claims they can thicken, strengthen, and add shine and volume to hair are not supported by science. This article discusses the possible benefits of biotin for your hair and health. It also covers the potential side effects that may come with biotin supplement use.
Biotin is an important component of enzymes in the body that break down certain substances like fats, carbohydrates, and others. There isn't a good laboratory test for detecting biotin deficiency, so this condition is usually identified by its symptoms, which include thinning of the hair (frequently with loss of hair color) and red scaly rash around the eyes, nose, and mouth. Nervous system symptoms include depression, exhaustion, hallucinations, and tingling of the arms and legs. There is some evidence that diabetes could result in biotin deficiency.
Biotin is an essential vitamin meaning that your body needs this micronutrient to function properly. The biotin you consume in foods helps your body turn the food you eat (protein, carbohydrates, and fat) into energy.Taking a biotin supplement is likely effective for treating biotin deficiency. However, some biotin supplements claim to have additional health benefits that are not supported by scientific evidence.
A handful of research studies have shown that biotin supplementation may help stimulate hair regrowth in people who have a clinical biotin deficiency or alopecia (hair loss). In people with temporary hair loss, studies have shown that supplements containing biotin significantly improved hair growth after 90 days.1 That said, researchers also note that hair regrowth is often caused by many factors and may not be due to biotin supplementation at all. 2 Furthermore, there is no evidence that biotin supplementation is beneficial for people who do not have an underlying condition causing their hair to thin.
