Our favorite overall hairdryer has to be the GHD Air Professional Performance Hairdryer. The motor is great (so no burn out), it has all the ionic/diffusing/ergonomic perks you could ever want, and it works for left-handed or right-handed users. For waves and curls in particular, the DevaCurl DevaFuser Diffuser and Hairdryer is the stuff of legend—no frizz, no tangles, and a super cute design. And if you want the fastest dry possible, you should definitely check out the CHI Hairdryer.
