Who wants a hairbrush that’s connected to the internet? Well, its manufacturers – Kérastase, Withings and L’Oréal – seem pretty excited about it. They unveiled the gadget at the CES technology show in Las Vegas to great fanfare.
The £160 Hair Coach is part of the “internet of things” – devices that promise to be smarter and cooler because they are connected to the web. It contains a microphone that promises to record the sound of breaking hair, and multiple sensors that will send data about your brushing technique to an app on your phone.
