The Dyson Supersonic Hair Dryer is ultra-fast drying and has intelligent heat control to protect against extreme heat damage. Now with five attachments to style your hair your way, including the new Flyaway attachment.

  • Fast drying: The small, powerful Dyson digital motor V9 combined with Air Multiplier technology produces a high-pressure, high-velocity jet of controlled air, for fast drying and precision styling.
  • Intelligent heat control: Dyson Supersonic Hair Dryer measures air temperature over 40 times a second, and regulates the heat. This prevents extreme heat damage, to help protect your hair's shine.
  • Engineered for different hair types: After rigorously testing different hair types in our laboratories, Dyson has engineered a range of attachments designed to style different types of hair.
  • Five attachments to style different hair types: Flyaway attachment – Hides flyaways under longer hair for a smooth, shiny finish¹.
  • Magnetic attachments: Allowing you to adjust quickly and easily
  • Cool to touch: With Heat Shield technology, the surfaces of the attachments stay cool. Even during close-up styling.
  • Lightweight and balanced: Dyson has turned convention on its head and put the motor in the handle, completely rebalancing the dryer's weight and shape.
  • Acoustically tuned: The powerful motor is tuned to produce one inaudible frequency.
  • Multiple speed and heat settings: 3 speed settings – High for fast drying and styling, medium for regular drying, and low for diffusing.
  • Negative ions: Help reduce static in the hair.
