It did for me...though I barely use it anymore cuz I'm avoiding heat this summer. I bought the t3 and it was great for me cuz I'm generally hopeless with a hair dryer. The best part for me is how lightweight it is, so my arms don't get tired and I'm able to "give it my all" longer. It's pretty quiet, too. My hair didn't feel as damaged (I'm not fooled though, I know it was).
Having said that, I know people who didn't find it worth it.
