Hahaha! I just posted a similar thread about hair styling! Hopefully we'll get good advice!

Go to your stylist and ask them to give you a trim to reshape it.

i am trying to grow my hair out as well and was chided by a hairstylist for not getting semi - regular trimmings...at least once every three months. She said that its not just about split ends. The problem is the split can end up running all the way up the hair shaft if you let it sit too long. This is the first time regular trims made sense to me while growing hair out - i previously thought it was a conspiracy to steal my money.

So I'd say, lay off the heat styling, get a good balanced shampoo - protien for strength, moisture for softness (another one from the hairstylist) - and trim once every three months. Also, don't wash your hair with shampoo more than once every other day, even moisturizing shampoo. If your hair needs a refresh on an off day, just use conditioner. Should be fine unless you have been rolling in the mud that day.

I've been doing that and my hair has been growing and, more importantly, staying pretty healthy throughout so i hopefully wont have to trim much off when i go in again.
