How can I keep my hair straight?
I have really thick brown hair. When I say thick, I mean THICK ! My hair is naturally wavy, but when I wear it down, I prefer it straight. My only problem is that it doesn't like to stay straight. I will flatiron my hair, and it will say straight for a couple hours then start to wave again, mainly on the ends and around my face. What can I do to keep it straighter longer? Thanks!
