I've been straightening my hair since I was 13; (I'm 18 now) and I've always had no problem getting my hair straight. I've recently gotten a haircut, and since my hair is so thick, I haven't been able to straighten it properly. It always ends up looking like a girl with naturally straight hair only brushed her hair. I don't like this look on me, because it looks sloppy. What can I do? I just want my pin straight hair back.
