I have alot of prego friends or have been around alot.. and they always say that after taking prenatal vitamins that their hair and nails and skin are always much more healthier and seem to grow faster cause of all the vitamins that are in them... that could be something you could try.. not sure how true it is or if it works but i have heard non prego people have taken them, but maybe you could look into what vitamin helps your hair grow and take a supplement but not overdue it... i dunno, lol but i know not cutting it doesnt help, cause then the ends are not healthy which makes it not gorw.. so when you get it cut get it cut more often but not as much each time... you might want to check that with your hair stylist though..

But I am in the same boat.. I want long hair, but I always end up chopping it off right when it finally starts to get long, haha
