Abstract
A hair curler has a barrel with an exposed heating element and a clamping member which clamps hair to the heating element exposed on the barrel for providing tight curls. The heating element is in the form of a plurality of resistor segments extending lengthwise of the barrel and being spaced circumferentially around the barrel with the longitudinal ends thereof being connected. The resistor segments, which are mounted at one circumferential portion of the barrel in closely adjacent relation to the clamping member, are arranged to give off a greater amount of heat than the remaining resistor segments mounted at the other circumferential portion of the barrel located away from the clamping member.
