it's a combination of vitamins A, C, E, B-complex, zinc, and protein..
vitamin C
It's good if you took a multivitamin with all these combined because it will not only help your hair but your skin and also repair it on the inside out. But the vitamin that is put in special shampoos or pills to promote new hair growth is vitamin E.
