Biotin

Biotin, also known as vitamin B7, is important for maintaining healthy hair. In the context of hair loss treatments, Dr. Andrew Huberman discussed the potential benefits of biotin-enriched shampoos. Although the effectiveness of such shampoos in significantly increasing biotin's incorporation into the hair is uncertain, having sufficient biotin is recognized as beneficial for hair health. Thus, using shampoos with added biotin might provide some advantage in ensuring adequate biotin levels in the hair 1.
