Abstract: An apparatus for waving the hair comprises a pair of snap-together complementary pieces made of resilient plastic. The pieces when fitted together define a sinuous or swirled path between them. When the pieces are snapped together over a strand of hair, the strand is held in a sinuous waving shape for imparting a "perm". A first piece includes a cylindrical roller and two partial cylindrical cages, resembling those used in ordinary hair rollers except for their mutual attachment and the angular cut from each cage. The second, mating piece includes one cage and two rollers. In both pieces a cage is tangentially attached to a roller at two places. Each roller or cage on one piece mates to a respective cage or roller on the other piece. The pieces snap together by forcing the middle roller of the first piece between the two rollers of the second piece into the cage of second piece; the two rollers of second piece simultaneously snap into the two cages of the first piece.
