What is the best hair growth vitamin?

I cut my hair really short due to real bad damaged hair. My hair was all the way down to my butt. Anyways I really want my long hair back but growing it is not that easy it takes forever to grow. So to speed the process up what are the best vitamins that I can buy to make it grow fast and healthy. Anyone out there tried any that they can honestly say that their hair grew.

The best thing to use is an over the counter vitamin called biotin. It works really well at helping the hair growth process. I've used it, and it really does make a difference...What is the best hair growth vitamin?
i've read rave reviews about a vitamin by Ren茅 Furterer called Vitalfan Antichute Thin Hair supplements. apparently the olsen twins take them to maintain their healthy hair. i read it in elle magazine. you can go to sephora.com and order them. they were sold out for a while!





you could also take biotin vitamin supplements which you can get at the local drug store.
Buy a soy protein shake powder and have a glass a day to supplement your regular diet.
if you can find any sort of shampoo that contains burdock excracts, that will probably double your hair growth rate:)
