They tell you that a good hair cut makes all the difference. Then they say, it's all about the styling products. Oh, and don't forget the boar bristle brush. Truly none of these things can hurt, but to experience a great at-home hair dryer is like... wearing Jo Malone after years of Jean Nate.
The Theorie 3100 SAGA Hair Dryer is unlike any I've ever used before. Not only is it ergonomically designed, but it's indestructible (although it hasn't met my sister yet!) and can handle heat output over 300 degrees. Plus it comes in a gorgeous box with manual and certification. It doesn't help your hair any... but good icing makes good cake all the better!
It's got a professional brushless motor, lightweight and rubberized design--so it's comfortable to hold, a 30,000-hour motor life (again, it hasn't met my sister.) and a lifetime warranty.
I'm not going to say it's inexpensive, but I will say again: Lifetime Warranty.
