Biotin is a water-soluble B vitamin that is often promoted to support hair growth. It is commonly found in hair growth supplements and hair products, such as shampoos and conditioners. Biotin may support hair growth in people whose hair thinning or loss occurs due to a biotin deficiency. However, there is limited evidence to suggest that supplementing with biotin promotes hair growth in non-deficient individuals. Some studies have shown potential benefits, but more research is needed to confirm the effectiveness of biotin for hair growth in healthy individuals. Biotin supplements are unlikely to cause harm, but they are not proven to help with hair, skin, and nail health
. As for the details of hair growth products containing biotin, they often contain multiple ingredients in addition to biotin. For example, a hair growth serum may contain ingredients such as D Panthenol (Pro-Vitamin B5), Pisum Sativum Pea Sprout Extract, and other active ingredients and nutrients
. Similarly, a hair growth supplement may contain ingredients like Saw Palmetto, Keratin, Horsetail, and Organic Castor Oil, in addition to biotin
. In summary, while biotin may have some benefits for hair growth, especially in individuals with a biotin deficiency, the evidence is limited, and more research is needed to determine its effectiveness for promoting hair growth in non-deficient individuals. Hair growth products containing biotin often contain multiple ingredients, and their effectiveness may vary depending on the individual and the specific product.
