  • Patent number: 5526578
    Abstract: A generally disk-shaped comb-type hair dryer with drying air discharge nozzles projecting from a concave bottom surface. The bottom surface of the disk shaped hair dryer housing is gently concave in a manner to ergonomically conform the distal ends of the discharge nozzles to the outer contour of the human head. Heated air is emitted from the hair dryer discharge nozzles at the level of, or immediately above the level of, the scalp and is directed parallel to the scalp or upwardly such that there is no waste of air flow, no waste of heat, great efficiency in drying and no irritation of the scalp. The flow of air away from the scalp produces a fuller bodied hair style.
