The Dyson Supersonic is the benchmark fast-drying dryer and the dryer most others are measured against. TechGearLab scored it 86 out of 100, the top mark in their test group, praising its powerful, well-controlled airflow and handle-mounted motor. It is not always the single fastest in raw minutes, but its combination of speed, low heat damage, balance, and quiet operation is unmatched. The price is the only real barrier.
- — Highest-ranked dryer in TechGearLab's lab testing (86/100), with airflow that cut drying time roughly in half versus a standard dryer
- — Digital V9 motor sits in the handle, so the tool is exceptionally well-balanced and light on the wrist during long blowouts
- — Intelligent heat control measures air temperature many times a second to keep the dryer from scorching hair
- — Among the most expensive consumer hair dryers on the market at around $430
- — In one head-to-head test it took 30 minutes to fully dry thick hair versus 20 for the Shark HyperAIR, so it is not always the literal fastest
- — Replacement and accessory costs are high, and the proprietary attachments do not fit other brands
