The dyson supersonic hair dryer uses intelligent heat control to maintain an optimum temperature, helping to prevent extreme heat damage. Less damaged hair reflects light in a single direction, making the hair appear shiny. With 4 precise heat settings (100c, 80c, 60c, 28c), you can choose a temperature that is suitable to your drying or styling needs. The supersonic hair dryer uses air multiplier technology to create a high-pressure, high-velocity jet of air that exits the amplifier, tripling airflow. In addition, negative ions help to reduce static. It comes with 3 precise speed settings: Fast drying, regular drying and styling. The dyson supersonic hair dryer comes with magnetic attachments so you can adjust quickly and easily. With heat shield technology, the surfaces of the attachments stay cool, even during close up styling. , Voltage: 220-240 V
