Worldwide hair expertise Kérastase and smart technology leader Nokia have collaborated to unveil the world’s first smart hairbrush – Hair Couch, created to measure the quality of hair, the effects of different hair care routines and provide personalized advice. Conductivity sensors are built in the brush and send feedback to your smart phone. Taking external factors like humidity, temperature, UV and wind into account, it provides insights into hair’s manageability, frizziness, dryness, split ends and breakage. Hair Couch also analyzes your brushing patterns, pressure applied and brush stroke counts to measure the effectiveness of your brushing habits. Afterwards, it will provide you with a personal diagnosis offering personalized tips and real-time product recommendations. Its lightweight design features a comfortable grip and a curved paddle covered with a combination of professional-grade boar’s hair and nylon bristles.
