The Parlux Alyon Ionizer 2250W Tech Dryer Turquoise– Hair Free System technology. Any hair that enters the dryer is forced to the back of the dryer motor and concentrated on a removable screw that is detached from the back of the dryer. This removes aspirated hair that could otherwise cause the dryer to overheat and decrease the lifespan and power of the motor. This system keeps the motor working at optimum conditions and ensures a longer lifespan with no unnecessary heat build-up.
