Which vitamin is best for hair?
One of the best known vitamins for hair growth is a B-vitamin called biotin. Other hair vitamins are Vit A, C and E
Hair always grow according to its growth cycle but the total transition to old normal hair depends on the cause of hair loss. If hair loss is secondary to genetics then re-growth is doubtful unless a medical intervention is done. Hair loss secondary to infection, nutritional deficiency and damage may regrow once the cause is taken care.
