business news in context, analysis with attitude

AdWeek reports that L'Oreal-owned Kérastase has "announced a new brush dubbed Hair Coach that collects and analyzes grooming patterns to recommend the right products and techniques."

That's right. It is a smart, connected hairbrush.

Here's how AdWeek describes it:

"Each brush contains a tiny microphone that records the sound of brushing to detect if hair is dry, frizzy or prone to breaking. Built-in sensors then determine if someone is brushing hair when it's dry or wet while a gyroscope and accelerometer count the average number of brush strokes and measure the force used to brush hair.

"The styling tool uses Wi-Fi and Bluetooth technology to deliver all of that data to the app. The app then breaks down beauty habits using algorithms developed by L'Oreal to show consumers a chart of their routines and give tips on improving the health of their hair. For example, someone brushing too hard might get a message recommending softer strokes. Or the app may suggest that consumers brush more if the amount of strokes is too low.

"Each user is also given a score between one and 100 that assesses the quality of their hair. In addition to the data collected from the brush, the app also pulls in local weather information to recommend Kérastase products. Consumers can then click the product recommendation links and shop from Kérastase's website.
No specific price has been set for the brush, but it is expected to be under $200.
KC's View:
I'm not entirely sure how big the market will be for something like this, but it isn't hard to imagine that the prices will come down and the technology will become more available.

Regardless, it seems clear that connectivity and a desire for greater access to information are trends that are affecting every part of our lives. Even our follicles.
