I have naturally curly hair so it didn't completely eliminate the frizz, but it did a great job compared to other hair dryers I have used [When straightening].  It is lightweight and doesn't seem to run as hot on my scalp as all the others I have tried, but definitely dries my hair as quick if not quicker.  I'm completely happy with this hair dryer and have already been recommending it to my friends, so get you one & recommend to yours! :)
