Beth, that's terrible! I'm sorry your perm went wrong. I'd wash it, like the others said. I also like the idea of wearing headscarves or headbands. Could you go to another beauty salon and see if they can relax it or fix it in some way?
You're not stupid for going back. If you're unhappy with a haircut, you should be able to go back and trust that they'll make it better for you. I'm just sorry that the person who did your hair didn't know what she doing!
