Abstract: A comb for removing lice and nits from the hair is formed by a base and a plurality of teeth extending from the base in substantially the same direction. The longitudinal axis of each tooth is parallel to the longitudinal axis of each other tooth. Each tooth has a polygonal cross sectional shape such as in the form of a modified triangle. The cross sectional dimensions of each tooth enlarge from the free end of each tooth toward the base so that the spacing between adjacent teeth narrows toward the base. The facing edges of adjacent teeth interact with each other to capture lice and nits therebetween. A rib is provided longitudinally along one of the faces of each tooth.
