The CHI Rocket Professional Hair Dryer is the most revolutionary hair dryer in the industry and the latest in Advanced American Technology. This lightweight quiet dryer utilizes ceramic technology, negative ions, far infrared heat and low EMF to provide the healthiest hair-drying experience around. The powerful motor generates negative ions and far infrared heat with the lowest output of EMF (Electro Magnetic Frequency) for static free results. CHI hair dryers are famous for producing negative ions that diffuse the water molecules on the hair into micro fine particles, improving the hair's moisture balance and enhancing shine while reducing frizz. With 1800 powerful watts, the CHI Rocket reduces drying time up to 50%.
