ok... as far as the prenatal vitamins... any kind of vitamins can help your hair grow, but i think being pregnant period makes your hair grow faster... it can change the texture and color (mine turned darker and redder and the texture changed) but it grew extremely fast while i was pregnant and i didnt' take prenatal vitamins. here are some tips though... eat lots of protein like someone said in an earlier post. also, wearing your hair in a pony tail (when it gets long enough) is supposed to make your hair grow faster - just don't get those pony tail holders with those metal things since it will make your hair break. i massage my head when i wash my hair... might sound crazy, but i honestly think it works... maybe stimulates? anyway, just thought i'd put in my 2 cents.
