Ordinary hair dryers blow in one continuous direction, causing hotspots. But the Oscillating Air-Flow Professional Hair Dryer varies the air flow for faster, more comfortable drying. A slight turn of the control ring oscillates the air flow to create a vertical or horizontal wave to provide faster drying, an expanded drying area and deep root penetration without hotspots. Oscillation can also be turned off for a standard air flow. Weighs just 2 lbs. and features a powerful 1875-Watt motor. Includes diffuser and concentrator attachments.
