ABSTRACT:
An electric curling iron for producing a spiral curl giving the impression of a stream-like natural and soft wave is constructed in the form of a scissors having one blade comprising an electrically heated rod and the other blade comprising a clamp cooperating with the rod to press hair to be curled therebetween. The surface of the rod has a plurality of side by side spiral polygonal edges. The clamp is an arcuately shaped cover longitudinally coextensive with the rod and in contact with the polygonal edges thereby, leaving a free space between the clamp and heater rod for the escape of vapor. The arcuately shaped clamp may have a radius smaller than that of the rod and may be provided with a rubber cover. Since the edges are obliquely pressed against the hair during use possible hair damage by heat and pressure is reduced.
