Just hook this Salon Smart Portable Hair Dryer Bonnet up to a standard hair dryer and you will have a professional salon drying system in your own home. Made of heat resistant nylon, the bonnet circulates hot air around the entire head for processing under heat. Easy to install and use. Perfect for heating rollers, heat activated hairdressing treatments, hair conditioners and hot oils. We recommend covering hair first with a processing cap (for treatments) or a hair net (for roller sets).
