Curls won't hurt career.
From CurlTalker Kourtnie: "I was watching an episode (of America's Next Top Model) when the models were getting their hair done—extensions, color, etc. One girl had really pretty wavy/curly hair, and they straightened it, which she didn't want them to do at all. But Tyra Banks said they had to do what would best for her career. That was a bunch of crap, I thought."
