Dyson Supersonic Hair Dryer
The Dyson Supersonic is the best hair dryer here. Dyson rates the brushless motor at 110,000 RPM, and the airflow it produces is what makes it fast on thick hair. The heat sensor checks air temperature 20 times a second and caps it, which keeps you clear of the 230°F range where the cuticle starts to break down. At 1.8 lbs it is the lightest of the five. It is also by far the most expensive. Best for daily use on thick or long hair.
