Abstract: Example embodiments relate to an improved plastic lice treatment comb as well as methods of manufacture and use of the comb. The lice plastic comb may have a front surface, a back surface, a grip portion, and a plurality of rigid plastic tines extending from the grip portion. The front surface of the grip portion includes an elongated plastic flow ridge which is adjacent to the base ends of the tines. The back surface of the grip portion includes a plastic flow restriction channel, which is spaced slightly back from the base ends of the tines.
