It uses a novel, brushless digital motor that’s much smaller and much lighter than traditional a hair dryer motor, meaning a quieter — but not weaker — airflow that’s amplified up to three times, thanks to Dyson’s Air Multiplier technology. “Call me crazy, but I felt like it dried my hair faster,” said one tester. In fact, in our Lab tests, the motor on the Supersonic produced the best airflow compared to any other hair dryer tested, and it dried hair the fastest.
Though it earned the highest consumer satisfaction score of all the hair dryers we’ve tested, some consumers thought the Supersonic was almost too good, and said, “The air was so strong, even on low, that the attachment felt necessary for any kind of control.” I agree: If you’re not careful with how you use the hair dryer, the airflow is so strong that it can cause more harm (e.g. frizz, tangles) than good sometimes.
What is so special about the Dyson hair dryer?
The motor is lighter, smaller, and lives in the handle: Unlike most hair dryers, the tiny motor is located at the handle of the dryer rather than the end of the dryer’s head. Air is brought in through a filter at the bottom of the dryer’s handle, and expelled through thin vents that surround the circular head of the hair dryer. One drawback is that the filter’s placement poses a learning curve: “If you hold [the handle] toward the end, it closes the vent and restricts airflow,” said one tester
It’s easier to hold: The motor placement makes for a more comfortable drying experience. After a few minutes of holding the hair dryer overhead, my shoulders don’t burn the same way they do with other hair dryers, since the heaviest part of the hair dryer is in my hand, not balanced in a top-heavy nozzle.
Your hair won’t get caught in the dryer: Since Dyson moved the vent to the bottom of the handle, our testers loved that they didn’t have to be afraid of getting their hair caught on a back vent. That means no more burnt hair smell or cutting tangled strands out of the dryer’s motor (can I get a hallelujah, fellow long-haired ladies?).
