You can try putting a little bit of mousse in your hair after you get out of the shower while it is damp, let it dry and then straighten. That should help. :)

Straighteners you but don't really work that well. They might start out ok, but don't last. You can get it done by a stylist and it'll work better but it's pretty hard on your hair. Maybe you should try a style that uses the natural curl.

The mousse thing should definitely help but also straighten your hair in smaller sections and go over it a couple times If you have the same problem my brother does (thinging it is) then it's just how big the section of hair is that your straightening Also you can let your hair get a little greasy after a day or two it should stay sraight.. Hope I helped c:

Mouse or gel work after a shower. So does layering in smaller sections to straighten, as well as blowdrying straight although it wont stay straight your hair will be easier with the straighter going over it. Hope this helps
