Vitamin A is involved in the growth and maintenance of hair, as well as the skin. Vitamin A regulates the synthesis of retinoic acid in the hair follicle. Vitamin A is added to skin care products and is beneficial for hair growth as well. It can be applied to the hair shaft and massaged in, as well as taken internally.
B vitamins help grow hair by aiding the body to handle stress and stress can cause hair loss. Inositol, one of the B vitamins, has been shown to speed hair growth. B12 is another B vitamin that prevents hair loss because B12 is a component of the hair itself. Many people are deficient in this nutrient, especially vegetarians, because B12 is mainly found in meat and eggs. The B vitamins are best taken together and are frequently sold with the label B Complex.
Vitamin C also helps the body absorb iron, which is needed to grow hair. The human body does not make its own vitamin C, so food or supplement sources are required, such as fruits and vegetables. The recommended daily dose of vitamin C is 1000 to 2000 mg a daily.
Taking vitamin D stops hair loss. Research published in 2009 reports that vitamin D has been used to treat skin conditions such as psoriasis for over 10 years. Vitamin D reduces hair loss by stimulating the hair follicle and the cells that form the hair shaft. Following research that shows a worldwide vitamin D deficiency epidemic, the recommended daily intake of vitamin D has been changed from 400 to at least 1000 IU per day.
Vitamin E builds capillaries in the body and improved blood flow on the scalp encourages hair growth. Adding 400 IU a day of vitamin E to the diet stimulates the hair follicles that grow hair. Vitamin E can also be massaged into the scalp to encourage blood flow to the scalp."
