I've done it before. I just cut one curl at a time, going from side to side and then I did the back. If you could have someone help with the back, or at least guide you, that would be good too. Good luck! If you take it slow, I'm sure you'll be fine.
2b/3a, primarily use Jessicurl and DevaCurl products, Curls Hair Tea conditioner and various gels. I'm modified CG-ish since 5/04.
