Panasonic made a robotic hair-washing system. This robot uses plenty of hot water to loosen the hair, applies mousse along with shampoo, works both into the hair, and then rinses. What I find suspicious is that instead of a humanoid sitting in that chair it is a dummy. What you might wonder about after watching the clip is the idea that the same principle that was previously washing your car in a CarWash can now wash your head.
