YEARS ago this dryer was really popular: http://www.naturallycurly.com/curlta...pj-attack.html
Unfortunately, Sally's doesn't carry it anymore. At least you can see what people had to say about hat hat dryer, in general. I took mine out yesterday because of your question. Did a PT and sat under it after I styled my hair. Hair was fine, but not as curly. I think it was the product(s) I used and not the dryer. Usually, curls are tighter after PT. There wasn't any frizz. Once again, I think it was the PT and not the dryer.
