When I saw the press-release a couple days ago the hair dryer did not look very exciting. Now Nikkei Net published a story about the Matsushita Nanocare Hair Dryer with a live photo of the dryer. This thing looks like it is straight out of a Sci-fi movie.
The nano technology hair dryer gives the hair moisture by blowing nanometer-scale ions, while drying. The dryer has a little water tank and a ion generator. The nanocare hair dryer is supposedly helping with damaged hair.
