Jenna has the same problem. She almost "burns" all her hair off the back of her head its so frizzy. We usually have to wet it each day, and then comb it, and it goes back to its curls.
We have started to condition, but to be honest, I dont reckon it makes any difference.
But my girl is super curly, so its more of a problem associated with that I think.
We wont be getting her hair cut as its too cute, and I'm scared the curls will disappear
