Which vitamin is essential for healthy hair growth?

Biotin, also known as vitamin B7, is essential for healthy hair growth due to its critical role in the production of keratin, a protein that makes up hair. Biotin supports the infrastructure of hair, skin, and nails, ensuring they remain healthy. A deficiency in biotin can lead to hair thinning and loss, making it a key nutrient for maintaining hair strength and vitality.

While other vitamins like Vitamin A, Vitamin C, and Vitamin D also contribute to overall health and may have some benefits for skin and hair health, biotin is specifically recognized for its direct impact on hair growth and quality. Therefore, biotin stands out as the most relevant choice for promoting healthy hair growth.
