  • Patent number: 5231999
    Abstract: A comb for separating strands of hair to implement and facilitate highlighting, streaking or frosting is described. The comb comprises first and second rows of teeth which project angularly from a handle portion. The teeth in the first row are spaced to initially part and separate strands of hair during combing. The teeth in the second row are adjacent to the first row or teeth but in staggered relation thereto. The teeth in the second row are also shorter in length than the first row of teeth and tapered to provide a secondary partition and separation of strands confined between adjacent teeth of the first row. Each tooth in the second row is also formed with a hook that projects toward an adjacent tooth for engaging and separating alternate strands of hair from a grouping.
