Engineers have yet to devise an electronic replacement for hair stylists, but they have come up with a way to save time on your next visit to the salon. Panasonic has unveiled a prototype hair-washing machine that begins with a 3-D scan of the user’s head, then lathers, rinses, and repeats. Panasonic says the machine, which uses 16 mechanical fingers to massage in the shampoo and help wash it out, will be available for sale in 2012.
