I'm blogging about hair (It's a project. Don't ask.), and I need some interesting sites to get info off of.

OK so I assume you are just dying to know why I’m blogging about hair of all things.
I have this blog and lately I’ve been having trouble thinking of stuff to blog about, so this week I’m doing a “Ways to think about _______” thing (like Reader’s Digest) and every day I’m gonna call a friend and ask them what should go in the blank. Today my friend told me to do hair. So does anybody know of some good hair sites? I tried googling it and it gave me ways to style hair. that was NO help.
