Why Do You Need a Smart Hairbrush? Because You’re Worth It


These days, it seems like everything is connected to the internet. There are smart toys, connected cars and even connected cows. According to various studies, between 20.8 billion and 50.1 billion connected devices will be in use by 2020.  

Now, the internet of things has a new addition: a smart hairbrush.  

L’Oreal S.A., the French cosmetics powerhouse that owns The Body Shop and Lancome, recently unveiled the “world’s first smart hairbrush” at the 2017 Consumer Electronics Show (CES). Named the “Kerastase Hair Coach Powered by Withings,” the hairbrush of the future is a collaborative effort between L’Oreal, French luxury hair care company Kerastase and French consumer electronics company Withings. 

According to L’Oreal’s announcement, the brush features Withings’ sensors to “score the quality of hair and monitor the effects of different hair care routines.” The brush comes with an accompanying application that provides “additional insights and customized product recommendations to help people better care for their hair.” The smart hairbrush, which won the International CES Innovation Award, includes a microphone that listens to the sound of hair brushing, cells that measure the force that is applied to the hair and the scalp, a gyroscope and an accelerometer that analyze brushing patterns and count brush strokes as well as a conductivity sensor that determines if the brush is being used on wet or dry hair. 

This year’s CES featured other smart devices connecting all aspects of consumers’ daily lives to the internet. For the first time, the National Sleep Foundation organized a Sleep Tech event, which featured sleep enhancing technologies. Additionally, many companies showcased their digital assistants and other smart home techs.

Increased connectivity has its benefits, but also comes with many risks. In October, hackers were able use millions of malware-infected connected devices to launch a distributed denial-of-service attack that shut down numerous websites, including Netflix Inc. and Twitter Inc., by overloading them with traffic.
