The gadget that probably best encapsulates this week’s Consumer Electronics Show in Las Vegas does not look like a gadget at all. The new hairbrush from Kérastase has the same bristles and lacquered sheen as any of the L’Oréal brand’s salon products. There are no flashing lights or even a button to turn it on and off.
Yet hidden inside are microphones, motion and conductivity sensors, and wireless connectors that turn this $10 everyday object into what its makers bill as the “world’s first smart hairbrush”, costing close to $200. Artificial intelligence has made it to the boudoir.
The data gathered by the brush are sent to an app, where software algorithms produce a score for hair quality and recommend techniques — and L’Oréal products — that might improve it. The brush even vibrates if you brush too fast and damage your hair.
