Da bomb
This does what it says. I just got it and used it. It's almost as good as a hot iron. My thick, processed, and fine hair is curly/wavy. I didn't try to straighten my hair when it was dried naturally. I don't think that would work any better than it would with a hot iron. But I did use it on my hair that had been blow dried two days earlier and was misshapen. I usually have a kink in my hair right below the root. This kink is very hard to get out unless I wash and blow dry it  and then use a hot iron on it. I had the kink in my hair when I used it, and the brush straightened the kink.
