A hair curler roller having a top and bottom end adapted to be heated while its bottom end is seated on one of a plurality of identical frusto-conical, heated posts of a heating unit. The roller consists of a cylindrical shell of a material of low heat conductivity, such as a synthetic resin, provided on its outside with hair-gripping means, and of a sleeve of a material of high conductivity, such as aluminum, inserted into the shell in intimate contact therewith. The top of the roller is preferably closed by suitable cover or cap of a synthetic resin, while the shell and the sleeve are open at their bottom. The sleeve comprises an upper cylindrical main portion closely adhering to the inside of the shell, and a lower, short neck portion of a smaller diameter, spaced apart from the shell wall. The neck portion is slotted by a plurality of slots permitting the outward expansion of the neck portion conforming to the shape of the frusto-conical post on which it is positioned.
