Abstract
An appliance or device for treating hair includes a tubular barrel containing a generator for heat and vapor and a plurality of hair winding mandrels which are selectively slidably mounted over the tubular barrel. The mandrels have different external sizes and configurations, but have interior structures which, though they may differ, allow each mandrel to be used with the same tubular barrel. In one embodiment, the vapor and heat are conveyed from the tubular barrel to the exterior surfaces of the mandrels to treat hair by fins which form ducts within the mandrels that extend radially inwardly toward the tubular barrel. There are apertures both in the mandrels and the tubular barrel with which the ducts register to convey the vapor. Pivoted to each mandrel by means of a sliding pivot is a clip having a clamping portion for initially engaging hair before the hair is wound around the mandrel.
