  • Patent number: 4256127
    Abstract: A hair waving appliance of the type having a hood assembly includes a plurality of independently controllable heating means such as infrared heaters or lamps valves each disposed to heat a different hairline area of the head of a patron. A temperature control and a timer are provided for individual ones of the heating elements for controlling a temperature and a period of heating independently of one another. In addition, an ultrasonic atomizer is provided within the head supporting assembly to generate moisture-laden air mist, imparting longer-lasting curl retention. A heating temperature or a period of heating can be determined under the control of at least either the temperature control or the timer depending upon the hair nature of the hairline areas and personal taste of the patron.
