Vitamins= hair growth?

Hello everyone.

I been trying to make my hair grow longer and faster. I been taking prenatal vitamins for 3 months now and I just started taking Biotin 5000 mcg along with the prenatal vitamins about 5 days ago. I long until the Biotin will get into my system and/or I see a change in the lenght on my hair.

Thanks!
biotin does work bc it prevents your hair from breaking you will see results in about a month or so since hair only grows half and inch per month.
ummmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm your question????
