The ‘Kérastase Hair Coach Powered by Withings’ uses different sensors to provide information on hair quality and brushing patterns, in order to avoid unnecessary breakage. These include a microphone that listens to the sound of the hair being brushed, conductivity sensors to determine whether the hair is wet or dry, and an accelerometer and a gyroscope that signal if brushing becomes too vigorous.

The data is sent to a corresponding mobile app via Wi-Fi or Bluetooth, and the user is provided with a hair quality score and brushing tips. The brush has received one of this year’s International CES Innovation Awards.

The brush will be available mid-2017, retailing for under $200.
