Abstract: A hair curling device including a heatable rod having a plurality of longitudinal channels. A non-conductive roller having a cage-like body is provided with a plurality of mating strips or bars. When the roller is slidably mounted on the rod, a sufficient heated surface area of the rod remains exposed for applying heat directly to a wound tress. The rod may be removed from the formed curl leaving the roller to support the hair while it cools to operate as a hair setter. If the rod remains mated to the roller and left in the hair while the hair cools, the device operates as a curling iron or styling wand.
