Abstract
A heating type hair waving appliance includes a bonnet in which the hairline area of the head of a patron is inserted and a plurality of infrared radiation lamps serving as a source of heat for heating the hairline area. A controller is implemented with a microcomputer semiconductor integrated circuit for receiving inputs applied via an input keyboard and placing the plurality of the infrared lamps into predetermined conditions. A solid state display provides a display of the operative state of the infrared lamps and an ultrasonic type atomizer is provided for generating moisture-laden mist which in turn is guided into the interior of the bonnet.
