Dyson Supersonic Hair Dryer is a hair blow-dryer with a tiny internal motor and three magnetic styling attachments. I’ve become obsessed with this product ever since I started using it a few weeks ago. It’s the most powerful blow dryer I’ve ever used. I was shocked at how fast and strong the air was comes out. The Dyson cut the drying time in half, and really does my hair soft, smooth and incredibly shiny, even though I’m just rough-drying my hair.
