I have long, wavy hair and blow-dry with a diffuser about every other day. I had this hair dryer years ago and loved it. It lasted a long time, but I ended up buying a lighter-weight blow dryer after that. But that one sucked my long hair into the fan where it would tangle too much to pull out without breaking my hair. Then, if I did not clean out the fan, I smelled burned hair. Enough of that!I was excited to buy this hair dryer again. There is a filter over the fan that's much better at protecting your hair from being sucked into the fan, like dryers with just fine woven wire mesh. Plus, this does not cause frizz and over-drying. (see picture of my hair after a normal diffusing with minimal product). This fits my Segbeauty diffuser perfectly and dries my hair pretty quickly. And the cord is a mile long--so great when I'm traveling and outlets aren't in convenient places. Long cords are a long-haired, diffusing girl's friend since I can diffuse my hair upside down in a clean and comfortable place with lots of cord to move about-- not stuck in the bathroom or left pulling the cord out of the wall because the cord is too short. I have had this hair dryer going on two years. It's fabulous for so many reasons. Best dryer by far for long hair.
