The Dyson Supersonic hair dryer is engineered to protect hair from extreme heat damage for fast drying and precision styling. 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: Unlike some others, the 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 finish.¹ Styling concentrator – For precision styling. Diffuser – Helps reduce frizz and create defined curls and waves. Gentle air attachment – Fast yet gentle styling for fine hair and sensitive scalps. Wide-tooth comb – Helps shape and lengthen curly and textured hair as it dries.
