Think, for a moment, about the most useless invention you could possibly imagine. Is it… a hairbrush with a built-in accelerometer that tells your smartphone how fast you are brushing your locks?
If so, you’re in for a rude shock, because apparently it’s already been invented. Surprise!
Meet the Kérastase Hair Coach Powered by Withings, which is being heralded as the world’s first-ever “smart hairbrush”.
Because that’s just what we need in 2017, apparently.
Retailing at just under $200, and due to be released mid-2017, the hairbrush will tell its user whether they are brushing too vigorously, using too much force or holding their brush properly.
It can even assess your hair’s “frizziness” and “dryness”.
