Abstract
The self-tensioning hair waving rod includes a cylindrical sponge body and retainer means for holding a strand of hair wrapped around the sponge body. The sponge body is formed of a hydrophilic polymer which expands from a dry condition on application of water to increase its volume by at least 50%. This expansion tightens the wrapped hair strand and draws it into close proximity to the outer surface of the sponge body. This hair waving rod and its method of use are adapted for home permanents.
