Abstract
A hair roller assembly is shown which includes a hollow roller member (12 and 60) containing a consumable heat source (14 and 62). The heat source is slidable into and out of engagement with the roller member such that, after use, the heat source may be removed and discarded and the roller member reused with a fresh consumable heat source. The heat source may include combustible material (40) or reactants (80). The combustible material is ignited by an electrical heating element (42) connectable to a battery (50). The reactants, when activated by liquid from a syringe (84), create an exothermic reaction for heating the roller member and hair wound thereon. The reactants are contained in a rupturable container (82) which is ruptured by the syringe needle (96) upon actuation of the syringe.
