Ridiculous Products: Kérastase Hair Coach

The Consumer Electronics Show (also known as CES) just finished up last week, and as always, it was full of a plethora of technology you almost certainly don’t need. While it can be fun to see what’s coming in the future, it’s perhaps more enjoyable to laugh at the bizarre future some companies envision. To that end, allow me to present the Kérastase Hair Coach.

If you’ve ever thought “This hair brush just isn’t smart enough”, while also thinking “I’d be willing to spend almost two hundred dollars on a hairbrush”, then the Hair Coach is for you. Of course, it’s likely that this site is not for you, so you may wish to stop reading now.


The Hair Coach is much like Zoolander, in that it’s not an ambi-turner, and also because it’s very stupid.

The CEO of Withings, the company behind the Hair Coach, was quoted as saying “The last thing we want to do is turn a simple device into a complex device”. So naturally, his company added wi-fi and Bluetooth to a hairbrush. But they didn’t stop there. The brush also includes (taken directly from their press release):

  • A microphone that listens to the sound of hair brushing to identify patterns, providing insights into manageability, frizziness, dryness, split ends and breakage.

  • 3-axis load cells that measure the force applied to the hair and the scalp when brushing.

  • An accelerometer and a gyroscope which help further analyze brushing patterns and count brush strokes, with haptic feedback signaling if brushing is too vigorous.

  • Conductivity sensors to determine if the brush is being used on dry or wet hair, in order to provide an accurate hair measurement.

If you’ve ever felt like you weren’t brushing up to your full potential, the solution is here. If you were perfectly at peace with your hair brushing, and your life in general, I’m sorry to tell you those days are over. You’re bad at brushing, and you should feel bad about your brushing. Only the Hair Coach can save you now.

I recognize that I am far from the target market for this device. I won’t even venture a prediction that this product will be unsuccessful. I will however state, without equivocation, that this is a ridiculous product which should not exist.
