Abstract: A microwave heatable hair curler comprised of a pair of rigid, hollow, concentric cylinders sealed at both ends to create an annular space therebetween, with a heat absorbant material contained in this annular space. The gel is capable of being heated in a microwave oven to a hair curling temperature and capable of maintaining such temperature for a time sufficient for hair curling to take place. The gel contains a biocide so that it can be permanently sealed in the curler.
