<p>A heatable hair roller for use in combination with a heating unit, the heatable hair roller being formed of a tubular body having an alloy therein with a predetermined Curie temperature, an electrical heating element in heat transfer relation with the alloy and having contacts at opposite ends of the tubular body and apertures in the tubular body at the opposite ends aligned with the contacts, and the heating unit including a ramp having a heating position, a permanent magnet carried by the ramp at the heating position for magnetically holding a hair roller to be heated thereat and a pair of electrical contacts disposed on opposite sides of the ramp at the heating position and protruding from the ramp to be received in the apertures of a hair roller to be heated to provide electricity to the exposed contacts in the hair roller. The permanent magnet holds a hair roller to be heated at the heating position on the ramp until the alloy within the hair roller reaches the predetermined Curie temperature at which time the hair roller is released to roll down the ramp.</p> |
