I've seen people with wavy hair (not curly) and i'm wondering how they do it. I've tried braiding it and stuff before i sleep; it doesnt really work.

I'm wondering if they use a crimper to do that? Is there a crimper that doesnt give you such harsh "crimps" like this? (this is what i dont want)

(I cant find a picture of exactly what I want, but I want small waves without the harsh crimped look?)
