I straighten my hair...why some days does it curl and some days it doesn't?

thats so werid! i recommend getting a straightening perm. but reallly, dont worry about your hair to much otherwise you may look distracted and worried when you are hanging out/talking with her. try to focus on her and forget about what you look like. if shes a girl worth spending your time with she wont care! best of luck to you!!!
