Why put a microphone in a hairbrush?
Answer: to listen for breaking hairs, of course!
Cosmetic company L’Oreal launched a $200 hairbrush to help users monitor their daily haircare regimen during the 2017 Consumer Electronic Show (CES) in Las Vegas. The pricey beauty kit contains a microphone and several other sensors that alert the user if they are brushing with too much gusto. Data from the device is transmitted to an app via Wi-Fi or Bluetooth, according to the BBC.
