Regular hair brushing can be a healthy thing. My mom (or maybe it was my grandmother) was a big proponent of the “one hundred brushes before bed” habit which they said promoted healthy, shiny hair. But you can overdo it or do it wrong. That’s where this new smart brush from L’Oreal comes in. It listens–that is, it uses the audio generated by your brushing–and reports back to you. Tech comes to the rescue of frizziness and split ends.
And yes, it comes with an app.
