Does Biotin Grow Hair? The question of whether biotin, a water-soluble B vitamin, can promote hair growth has gained significant attention in recent years. Biotin, also known as vitamin B7, is an essential nutrient involved in various bodily processes, including the production of keratin, a crucial protein found in hair, skin, and nails.
The relevance of biotin for hair health lies in its role in keratin synthesis. Keratin provides strength and structure to hair strands, making it less prone to breakage and damage. Studies have shown that biotin deficiency can lead to hair loss and brittle nails, highlighting its importance in maintaining healthy hair growth.
