It was this very topic that brought me to nc.com in the first place. My hair used to be much more curly than it is now and I had a lot more of it. I used to have crap eating habits and smoked like a chimney and my hair was gorgeous. Now that I've had some kids and I'm taking better care of myself, my hair looks like caca. The curls came back, but much much looser. Now my roots are always flat when before I did have some curl and lift there.
