Here is a smart hairbrush with sensors to help you brush your hair better and monitor its health. It comes with a microphone that listens to the sound of hair brushing to identify patterns and let you know about frizziness, dryness, split ends and breakage.
The device lets you know how much force is applied to the hair. It comes with a accelerometer and gyroscope to analyze brushing patterns. The data is synced to your smartphone via WiFi and Bluetooth and visualized. Hair Coach will be available in Fall 2017.
