L’Oréal’s Smart Hairbrush Knows More About Your Hair Than Your Salon
Withings and Kérastase—L’Oréal’s professional products—have developed a smart hairbrush that can tell you more about the health of your locks than your hairdresser can.
That mic also works alongside a hidden three-axis load sensor that can measure the brushing force on your hair and scalp, providing immediate haptic feedback if you’re brushing too hard, while an accelerometer and gyroscope counts brush strokes during your morning routine. There’s even conductivity sensors in the bristles that can tell if your hair is wet or dry, so the waterproof brush can adjust its analysis of your technique accordingly.
All of the data collected by the Kérastase Hair Coach brush is passed onto its accompanying smartphone app over wi-fi or Bluetooth which collects additional environmental data—like temperature, humidity, UV, and wind—from local weather forecasts to give the user an overall hair quality score, but also tips on how to improve their brushing habits to in turn improve the health of their hair.
Because L’Oréal played a big part in the development of the smart brush, the app also makes recommendations on what Kérastase hair care products a user should be buying and using. So in addition to spending somewhere around $200 when it’s available mid-2017, the smart brush also puts L’Oréal ads on your smartphone, which sucks. But there’s no reason you can’t find cheaper versions of Kérastase’s recommended products if changing up your brushing routine alone isn’t improving the health of your hair.
