Well; next time pay attention to what the hair dresser put in your hair.. so that way it will be easier for you to fix your hair.
DUH. && you should go to the sstore, and I don't think it matters which store, because everyone has beauty supplies. But anyhoo go to the store and get some straightening spray, and some shine gel; and hairspray. when you straighten your hair, put the straightening cream/spray in your hair. then when your done with that straighten your hair. But when you straighten your hair, do it in layers 1 by 1. & put the rest of you hair that your not straightening in a clip above your head. & just do that.
