New. Never used. Open box. Advanced Plasma Technology: The Yiiho hair dryer uses a moisture-balancing dual ionic system that harnesses both negative and positive ions to eliminate static and frizz which results in truly smooth and hydrated styles. (Please be noted the hair dryer only works in US) Powerful and Efficient: In comparison with traditional hair dryers, our portable hair dryer has adopted a smart design equipped with a powerful 1800W motor that can ensure fast-drying performance (airspeed reaches 16.2m/s) and without creating frizz or damaging your hair.
