Abstract
A hair iron can give hair a sufficient amount of negative ions. The hair iron has a grip, and a hair-care section connected to the grip, having a heater for generating heat to hair for hair dressing. Further, it has a negative ion generator which generates negative ions due to discharge around an electrode therein to emit them toward hair held by the hair-care section. The hair-care section has a bar-like shape, and the heater is fixed to an outer surface of the bar-like shape. Then, by winding hair to the hair care section in the hair iron, hair dressing can be performed efficiently.
