The purple and black salon ionic dryer uses ionic technology to help retain moisture to prevent breakage so you can have shinier, healthier-looking hair styles. If you don't want to use the ionic technology you can turn it off with the on/off switch, and there is an on indicator light to let you know when the ionic technology is turned on. The balanced airflow design dries hair evenly and has 2 heat and speed setting so you can choose the setting for perfect drying and styling control. When you are done drying and styling your hair you can use the cool setting, which releases cool air to set the style. The large round hood of the dryer can accommodate a jumbo set of rollers. The dryer's convenient cord storage area and collapsible design makes storage and travelling easier.
