Haircare brand Kérastase, in partnership with Withings, has announced the launch of Kérastase Hair Coach Powered by Withings, the first ever smart hairbrush. The brush features Withings’ advanced sensors and seamless product design along with L’Oréal’s patent-pending signal analysis algorithms to score the quality of hair and monitor the effects of different hair care routines. An accompanying mobile app provides additional insights and customised product recommendations to help better care for hair.

The brush features a microphone that listens to the sound of hair brushing to identify patterns, providing insights into manageability, frizziness, dryness, split ends and breakage; while 3-xis load cells measure the force applied to the hair and scalp when brushing. An accelerometer and a gyroscope help further analyse brushing patterns and counts brush strokes, while conductivity sensors determine if the brush is being used on dry or wet hair.

The Kérastase Hair Coach Powered by Withings will officially launch mid-year in the UK, priced under £200.
