HAIR COACH, WITHINGS KERASTASE, 2017
Kerastase Hair Coach Powered by Withings, is the first connected brush. Developed in collaboration with the Tech Incubator of L’Oreal Research and Innovation, this brush combines the design and the advanced sensors developed by Withings with algorithms of analysis of signals (registered patent) elaborated by L’Oréal in order to evaluate the quality of the hair and measure the effects of different hair care routines.
It comes with a mobile application to access additional data and customized product recommendations to help users take better care of their hair.
The brush was awarded this year with a CES International Innovation Prize.
The brush has a set of sensors to collect information about hair quality :
- A microphone that records the sound generated by brushing and captures the patterns to provide clarity on the appearance of frizz, forks and breaks, as well as the maneuverability, flexibility or dryness of the hair.
- 3-axis force sensors that measure the force applied to the hair and scalp during brushing.
- An accelerometer and a gyroscope that can analyze the brushing method, with a haptic feedback that warns the user when his movements are too abrupt.
- Conductivity sensors to determine if the brush is used on dry or wet hair to provide accurate capillary measurements.
