Abstract
A hair treatment system and appliance which are precisely and accurately controlled by a microprocessor in which data stored in memory is utilized to control different types of hair treatment programs for different types of hair. The system is utilized in association with a head bonnet adapted to be placed about the hair being treated and having a heater therein for heating the hair during the treatment program. A control panel allows a selection and entry to be made on the type and porosity of the hair to be treated, from eleven different possible combinations thereof indicated on the panel. A memory has stored therein a treatment time and temperature for each of the possible combinations, and a processing circuit is responsive to the particular entry to retrieve the proper treatment time and temperature from memory. A separate temperature sensor probe is utilized to detect the temperature produced by the heater at the hair during its treatment. The processing circuit monitors the temperature sensor, and is responsive to its output to control the heater, maintaining it substantially at the temperature retrieved from memory. The processing circuit further monitors the treatment time, and turns off power to the heater after the correct treatment time has elapsed.
