I love this thread and it was the one that first led me to this website.
I started DD and I on curly girl method (or slightly modified version) a year and a half ago. The results are amazing in her case. In mine, not quite so dramatic, but she's a curly/wavy while I'm just a wavy.
So here's her results.
Before (sulfate shampoos, silicone conditioners and combing)
After 1st CG wash:
And now, 1 1/2 years later (sorry, weird face, but this pic was the best for her hair):
She still has to battle frizz, but that is more because she's 6 and a busy little girl and gets her hair into everything.
Sorry about the size
