Vitamins to help grow hair include B vitamins such as B12 and B3. Other vitamins to help with hair growth include biotin, vitamin C, vitamin D, vitamin E, vitamin A and zinc.
Biotin is known as the hair vitamin. This vitamin not only prevents brittle and fragile hair, but it also promotes hair growth. Vitamin B12 is one of the most crucial and beneficial vitamins for healthy hair. Deficiencies in Vitamin B12 result in hair loss. Therefore, consuming adequate amounts of this vitamin helps keep hair healthy and promote growth. Vitamin B3, also known as niacin, improves circulation in the scalp, which has a positive effect on hair growth. Vitamin C helps to prevent hair loss, but it is also important to the growth of hair because the body can not properly absorb vitamin B12 without sufficient amounts of vitamin C. Vitamin E not only improves circulation in the scalp, but it also has the ability to grow new blood vessels, promoting healthy and longer hair. Calcium is necessary for healthy hair follicles, and vitamin D helps the body absorb calcium. Vitamin A stimulates the hair follicles and helps the scalp produce sebum, which is responsible for keeping the scalp and the hair hydrated, promoting long growth. Zinc contributes to regeneration of cells and production of sebum.
