AMAZING - I'm now a believer.
My husband gave me this for Christmas and I have to say I was skeptical when I first saw these but I'm a believer now. I have medium/long and very thick hair that is naturally curly. To blow dry my hair then straighten it with a flat iron was a 2 hour process. I got tired of it and have just been leaving it curly. I let my hair dry by itself which is when it's the curliest and the following day I put this to test. I kid you not, in 15 minutes my hair wasn't curly anymore. Grant it, it wasn't stick straight but very close and no frizz.
