Abstract: A permanent wave apparatus for curling hair includes a perm roller having a cylindrical outer surface with four equally-spaced longitudinal rows of outwardly projecting teeth positioned thereon. As the hair strands are wrapped around the roller, the rows of teeth act to provide additional compression of the hair by pressing it more firmly together between adjacent teeth with each rotation of the roller. Thus, increased compression of the hair strands is a function of both the number of rotations or wraps of a roller and the compacting action of the hair between the roller teeth. End papers having a longitudinal I-shaped slot opening therein enhance wrapping of the hair by holding the ends of all of the hair strands in place during wrapping, thereby eliminating fish hooks or bent ends, and enabling perfect wraps, even on extemely texturized cuts. Plastic slide clips serve to secure the first roller used to wrap a given section of hair to the scalp to provide increased volume of the resulting curl at the scalp.
