What vitamins will help my hair grow long and how much a day should i take?

Hair growth: This is almost entirely due to genetics, although there are some diseases that will affect hair growth. Although there is no proof that vitamin supplements will help hair growth in people with a normal diet, the most commonly used vitamins for hair growth are the B-Vitamins, Vitamin C, and Vitamin E. http://www.ehow.com/how_4784460_increase-hair-growth-vitamins.html#ixzz3458igsoO
