The Collexia dryer has a unique patented dual-fan system that doubles the volume of airflow. Collexia greatly reduces drying times without increasing hair-damaging heat like other dryers. Plus unlike traditional longer, heavier dryers that need larger energy-sapping heating elements, the dual-fan system means the Collexia is lighter and up to third smaller than most dryers. The exceptional power of the Collexia means it can be used with the widest and slimmest nozzles available without any loss of power or control. This means you can dry full brush sized sections quicker and with more control.
