Hair vitamins for growth, a subcategory of dietary supplements, specifically target hair health and promote growth. One prominent example is biotin, a B vitamin essential for hair growth, found in foods like eggs, avocado, and almonds.
The relevance of hair vitamins for growth lies in their ability to provide nutrients often lacking in daily diets, crucial for healthy hair development. Benefits include improved hair strength, thickness, and reduced hair loss. A significant historical development was the discovery of biotin's role in hair growth in the 1950s, leading to its widespread use in hair care products.
