Do hair growth vitamins work?

I'm not to sure, I take prenatals and those seem to work, but with you taking hair growth now you do realize that it will probably cause the hair on your lefts and wherever else you shave to grow back faster... I take prenatals because I'm pregnant but there safe, so If i wanted my hair to grow faster I would probably take those even if i wasn't pregnant.... call a pharmacist first they should let you know if they are safe or not to take
