The Dyson Supersonic Hair Dryer delivers intelligent heat control for ultimate shine. The exit airflow temperature is measured 20 times a second, and regulated by a microprocessor. Heat is controlled intelligently, helping to prevent extreme heat damage. The Dyson motor V9 is small, fast and light. And with Air Multiplier technology, airflow is amplified by 3 times. It's the only manufactured hair dryer with the motor in the handle, not the head. A completely re-thought layout and engineered for balance. The Dyson Smoothing nozzle has been engineered to produce gentle, low-velocity airflow that dries and styles at the same time. Plus, it's the only hair dryer with magnetic attachments for easy fitting and rotation.
