Sensor-based styling system with real-time monitoring of the hydrogen bonding status in hair fibers, adaptive temperature control, and evidence-based service documentation.

Abstract

Data processing system for sensor-based control of a thermal hair styling tool (10), comprising: (a) a sensor unit integrated into the thermal styling tool (10) with an infrared temperature sensor (11) that detects the surface temperature of a strand of hair in the working area of ​​the styling tool in real time; (b) an evaluation unit (21) with a humidity inference module (22) that determines an evaporation characteristic and / or humidity characteristic from the temporal temperature profile of the detected hair surface temperature, and with a scoring unit that calculates a damage risk characteristic for the hair structure from the combination of the measured hair surface temperature and the determined characteristic;(c) a temperature control unit (23) which receives the damage risk indicator and adjusts the heating power of the styling tool by means of a closed-loop controller so that the heating power is automatically reduced when a predetermined threshold is undershot.;
