Abstract

Abstract A hair waving appliance includes a head receiving and confining assembly provided with a plurality of independently controllable electric heaters for heating different hairline areas of the head received therein. A plurality of temperature sensing probes, each associated with a respective one of the independently controllable heaters, are connected to a temperature control means for controlling the heating of the respective heaters. Each probe includes a temperature sensitive element enclosed in a spherical shell carried at the end of an elongated spring-biased cord or flexible pipe. The probes extend into the interior of the head receiving and confining assembly and are arranged to adaptably contact the hair on the respective portions of the head. The spherical members have a size at least equal to the size of the curler rods used to curl the hair. The appliance includes means for generating moisture-laden air at room temperature to impart moisture to the hair being treated.
