Which vitamin is crucial for maintaining healthy hair growth?

Biotin, also known as vitamin B7, plays a crucial role in maintaining healthy hair growth. It is a water-soluble vitamin that is part of the B-vitamin family, which is essential for converting nutrients into energy. Biotin is particularly known for its significant impact on keratin production, a key protein that makes up hair, skin, and nails.

A deficiency in biotin can lead to hair thinning and loss, as well as brittle hair and nails. Thus, including adequate amounts of biotin in a diet, whether through food sources like eggs, nuts, and seeds or through supplements, helps ensure that the body can support robust hair growth and overall hair health.

Other vitamins like C, D, and E also contribute to overall hair and skin health, but biotin stands out specifically for its direct role in hair growth and the maintenance of structural proteins associated with hair.
