This is the first time I have purchased an expensive hair dryer. A friend highly recommended this hair dryer and I’m glad I bought it. I have thin mainly straight (slightly wavy) hair. I was struggling with fly aways and frizzy hair. I decided to treat myself to this hair dryer hoping it would help tame my frizzy hair. It has helped so much. My hair is much smoother using this hair dryer . It’s nice and light & easy to use and much quieter then my old hair dryer. I highly recommend it.
