Mine hair *looks* wavier shorter - but only because the weight of the hair pulls the top straighter when it is quite long. Today my hair came out a lot like Charlize Theron's in the pic above, only not smooth on top like that. And more fuzzy. Fuzzy = cuddly, right?
Everybody is different, though. That's why no one haircutting method works for everybody, I think. It takes a while to figure out what length and style works with your hair.
