Which vitamin is crucial for healthy hair growth?

Vitamin B7, commonly known as biotin, plays a vital role in supporting healthy hair growth. Biotin is part of the B-vitamin family and is essential for the production of keratin, a key protein that makes up hair. A deficiency in biotin can lead to hair thinning or hair loss, as it is involved in metabolic processes that promote cell growth and the synthesis of fatty acids, which are important for maintaining hair health.

Additionally, biotin helps to improve the infrastructure of keratin, making hair stronger and less prone to breakage. It also supports the health of the scalp, which is crucial for optimal hair growth. While other vitamins like Vitamin A, C, and D may contribute to overall skin and hair health, biotin specifically is recognized for its direct impact on hair growth and maintenance.
