Kérastase Hair Coach Powered with Withings


PARIS — L’Oréal’s push for connected beauty continues, with the introduction of a smart hairbrush from its Kérastase brand.

The professional luxury hair-care label on Tuesday unveiled what it billed as the world’s first smart brush, created for maximum hair health, at the Consumer Electronics Show in Las Vegas, NV. Conceived with Withings, the French connected items maker, the brush scores hair quality and monitors the effects of various hair-care routines.

Called Kérastase Hair Coach Powered by Withings, it features sensors that collect data that is read by patent-pending signal analysis algorithms. An application linked to the brush provides further insights and customized product advice for consumers.

The brush is said to minimize hair damage — including split ends and other breakage — created by forceful brushing. That’s thanks to different sensors, such as a microphone that through sound can identify brushing patterns; cells measuring the force the brush applies to hair; an accelerometer and gyroscope to further analyze brushing patterns and count brush strokes, and conductivity sensors to note if the hair being brushed is wet or dry.

All of the data culled through the sensors feeds via Wifi or Bluetooth to the mobile app, called UX, which also analyzes weather-related factors, such as humidity, temperature and UV levels.

“Technology is transforming consumers’ daily beauty routines, and smart devices have huge potential to impact how we care for our hair and skin,” Guive Balooch, global vice president of L’Oréal’s research and innovation technology incubator, said in a statement.

The incubator is a lab within the company focused on technology innovations. Withings developed the brush’s hardware and Kérastase provided its professional hair-care expertise, and helped design the brush and its app. The brush will be available in select Kérastase hair salons and on the brand’s Web site starting mid-2017 for less than $200, according to L’Oréal.

Early last year, the company entered the wearable territory with My UV Patch, a stretchable skin sensor under its skin-care brand La Roche-Posay. The patch is a free-of-charge service to consumers, aiming to educate them on the potential dangers of sun exposure.

The ultra-thin, stretchable silicon patch serves as a sensor that can be placed anywhere on the body prone to sun damage. It’s compatible with Android and iPhone technology.
