Truth be told I don't think they help my hair grow faster, but I do think they help it grow stronger and so it breaks less allowing me to keep more hair on my hair... I take a b complex, hairfinity, biotin, msm, l-cysteine, vit c, a garlic supplement and I just finished my last bottle of nixion...yes, it sounds like alot but I don't have a very good diet, aside from eating a lot of steak and salad I don't really eat anything else during the day, I'm normally running around like a crazy person and carry a jug of water with me which gives me a false full feeling... When I wasn't taking supplements my hair was growing but is always have hundreds of short hairs in my bathroom sink when I combed it, now maybe I gave 2-5 a day
