I've been a beauty editor for nearly a decade and have been covering the best sales and deals for just as long — I've tried hundreds of hair tools from the best hair dryers to the best curling irons and more. This $100-off deal on the Dyson Supersonic Hair Dryer is the best deal I've ever seen, and today, during Amazon Prime Day, it's at its lowest price ever according to our price tracking tools.

The Dyson Supersonic Hair Dryer is our Good Housekeeping Institute Beauty Lab's top-tested hair dryer, drying hair faster than any model in our testing history. Our tests showed that since it operates at a lower temperature than the average hair dryer, this hair dryer is less damaging to hair. Testers with a range of hair types love how sleek it makes hair look, and I personally love how quickly and easily it dries my thick, curly, frizz-prone hair. I also appreciate that it's quieter than a traditional hair dryer.

Even at $100 off, $330 is still, of course, extremely pricey for a hair dryer. Based on its performance, its potential to keep hair healthier over time and how much testers (and I!) love it, I think it's a worthy investment if you have hard-to-style hair or are concerned about hair health longterm. If you've had your eye on this dryer (for yourself or as a gift), right now is definitely the time to buy.
