A hair curling roller system having a plurality of post members have substantially the same outer diameter for heating the rollers and a plurality of rollers having inner cavities for mounting the rollers on the posts with such inner cavities having substantially the same inner diameters. There are at least two groups of the rollers, with the outer diameter of the rollers of one group being larger than the outer diameter of the rollers of the other group. Each of the curling rollers includes an interior core member having an opening in one lateral end of the core member and longitudinally extending within the core member; this core member is formed of a material highly conductive of heat. In each of the larger rollers the interior core has a central hub and a plurality of heat radiating fins extending out from the hub for facilitating the transfer of heat to the outer surface of the roller. A hollow sleeve member with a flocked outer surface is arranged over the core member.
