Which nutrient is vital for maintaining healthy hair?

• A. Vitamin C
• B. Vitamin A
• C. Vitamin E
• D. Biotin

Answer: (D)

Biotin, also known as vitamin B7, is essential for maintaining healthy hair. It plays a significant role in the production of keratin, a key structural protein that makes up hair, skin, and nails. Biotin helps strengthen hair and can improve its overall texture and shine. Deficiencies in biotin may lead to hair thinning and loss, which underscores its importance in hair health. While vitamins C, A, and E all contribute to overall skin and health, they do not have the same direct impact on hair structure and growth as biotin does. For instance, vitamin C is primarily known for its antioxidant properties and role in collagen production; vitamin A supports healthy cell growth but isn't exclusively linked to hair, and vitamin E also serves as an antioxidant but focuses more on protecting hair from oxidative stress rather than promoting growth directly. Thus, biotin stands out as the key nutrient specifically vital for maintaining the health of hair.
