About
The Kérastase Hair Coach Powered by Withings minimizes hair breakage, taking advantage of multiple sensors that provide information on the quality of hair and brushing patterns. These include:
- A microphone that listens to the sound of hair brushing to identify patterns, providing insights into manageability, frizziness, dryness, split ends and breakage.
- 3-axis load cells that measure the force applied to the hair and the scalp when brushing.
- An accelerometer and a gyroscope which help further analyze brushing patterns and count brush strokes, with haptic feedback signaling if brushing is too vigorous.
- Conductivity sensors to determine if the brush is being used on dry or wet hair in order to provide an accurate hair measurement. The brush itself is splash proof.
These sensors feed data automatically via Wi-Fi or Bluetooth to a free mobile app that provides valuable information including a hair quality score, data on the effectiveness of brushing habits, personalized tips and Kérastase product recommendations.
