  • Patent number: 5551457
    Abstract: A rod device is provided for rolling a lock of hair during permanent wave hairstyling. The rod device comprises an elongated, rigid center core and a fine open mesh covering the center core. The center core includes a central opening extending from a first end of the core to a second end of the core such that air is permitted to pass through the center core. The mesh provides support for a lock of hair wrapped onto the mesh and core sufficient to prevent the hair from being damaged during permanent wave hairstyling. The mesh allows fluid applied to the hair to easily pass therethrough such that at least a portion of the fluid applied to the hair is evaporated as air passes through the center core.
