The Hair Coach measures the speed of brushing and the pressure applied to the scalp. If both are too high, haptic feedback indicates that you should perhaps be a little gentler. The smart brush also identifies your hair structure: Its built-in microphone, which registers the noises generated while brushing , recognizes if your hair is unruly, knotted or has even split ends and hair breakage. Specific conductivity sensors even enable the Hair Coach brush to determine whether your hair is dry or wet. The corresponding smartphone app provides further insight and recommends appropriate hair care products to help improve your hair’s health. The brush is slated to be launched in the fall of 2017, with the price expected to be less than 200 euros.
The Hair Coach development is a collaborative project between Withings , the French manufacturer of various health trackers, Kérastase (Nokia) and the L'Oréal Technology Incubator . L'Oréal recently significantly expanded its commitment to digital and technology startups, including through participation in the venture capitalist Partech Ventures , with which Nokia is also on board. A first result of the incubator in 2016 was My UV Patch , a networked, adhesive skin sensor that warns against excessive exposure to sunlight.
