i either straighten or curl my hair. i have weird in between hair with random cowlicks that looks like crap if i don't do anything to it. sometimes i do the whole scrunch thing but my hair is so unpredictable that sometimes it makes it look awesome and sometimes it just makes it look crappier.
i use a vidal sassoon iron right now but it's old and i hate it. i'm getting a bedhead iron for christmas. my friend that works at a salon suggested it and it's about fifty dollars less than a chi.
