Society’s current thirst for data can make wellness feel awfully stressful. Equipped with an army of trackers, it’s hard not to obsess over your caloric intake, step count, sleep patterns, heart rate, and everything in between—and by everything, we mean everything.

Beauty brand Kérastase and consumer electronics company Withings unveiled Tuesday the world’s first smart hairbrush, the Kérastase Hair Coach Powered by Withings. The high-tech brush uses technology from Withings, which has United States headquarters in Cambridge, to tell you more than you ever wanted to know about your hair.

Using a mélange of tools and sensors, the Hair Coach assesses your hair’s dryness, frizziness, split ends, and breakage (sort of like, say, a mirror); measures the force applied to the hair and scalp while brushing; counts brush strokes; and analyzes brushing technique, alerting you if it’s too rough. The tool can also tell if it’s brushing dry or wet hair, to ensure accuracy. Taking all of these measurements into account, it’ll provide you with a “hair quality score.”

As a final touch, the brush also connects to a mobile app that keeps you informed about humidity, temperature, UV light, and wind (sort of like, say, going outside), so you can factor the weather into your well-calculated hair plans.

“By using connected technologies to upgrade the hairbrush—something the average consumer uses every day—Withings and Kérastase have reinvented what a person’s relationship with their hair can look like and are showing how connected devices can revolutionize the beauty industry,” Guive Balooch, global vice president of L’Oréal’s Research and Innovation Technology Incubator said in a statement.

If you want to start obsessing over your locks, look out for these babies starting mid- to late-2017. According to the statement, they’ll cost somewhere “under $200.”
