The overarching theme, at least from what I can tell, about NaturallyCurly.com is to embrace your natural texture and be proud of it, curly-haired or not. That said, you can do whatever you want because it's your hair! But I think you should love it how it is.
I permed. I'm a "2" and I felt frustrated that I never knew how much wave or curl I'd get. But then I started feeling like I wanted to try to live with what I had, on wavy days and non-wavy days. Now I do, and it's much easier and more peaceful. Plus, no more perm smell!
The main thing is getting a cut that works with your type of hair. If I had stick straight hair, I would have a long blunt cut bob. Or a pixie.
