Known for its innovative, high-end engineering, the Dyson Supersonic was among the first hair dryers to place the motor in the handle and incorporate bladeless technology. Its efficient design and premium features make it a worthwhile investment, particularly for tech-savvy users, frequent at-home stylers, and professional salons seeking powerful airflow and fast drying.
In our tests, it outperformed every other model, drying hair faster than any dryer we’ve evaluated and setting the benchmark for all GH Beauty Lab measurements. It was also an initial adopter of magnetic attachments, and comes with five options tailored to different needs: two concentrators, a diffuser, a flyaway smoother, and a gentle air attachment for prep.
The tool is also a favorite among professional hairstylists. “It’s pricey but worth it,” Alvarez says. “The technology is so advanced, the cord is so long, and its three heat and airflow settings make it so efficient. It dries hair quickly, and the smoothing attachment gets rid of frizz without needing a styling product, making blowouts last longer.”
LAB TEST RESULTS: The Supersonic dried an 8-inch hair sample in just 54 seconds and delivered strong airflow in the Lab. Despite its longer, nontraditional handle, it feels balanced and is easy to maneuver while styling with a brush. Testers confirmed its fast-drying performance and gave it top scores for overall satisfaction, as well as high marks for ease of use, comfort, and the effectiveness of the cool shot. Lab experts also noted its extra-long (9 feet) and thick cord, which can be harder to store. The dryer is slightly heavier than some models, and the button placement may take getting used to.
WHAT TESTERS SAY: Consumer testers with various hair types (straight to curly) and lengths (short to very long) told us they loved this dryer. One tester said, “On the most humid days, it smoothed my hair faster than any dryer I’ve used.” Another added, “The air pressure was great, and it dried my hair faster than usual.”
