Abstract: Technologies are generally described for hair accessories and methods to make a material for repelling lice. The hair accessories may comprise a lice repellent oil infused within an injection molded plastic material. The infused injection molded plastic material may be in the shape of a hair accessory. The methods to make a material for repelling lice may comprise placing a plastic material into a mixing chamber. The methods may comprise placing a lice repellent oil into the mixing chamber. The methods may comprise mixing the plastic material and the lice repellent oil in the mixing chamber to produce an infused plastic material. The methods may comprise feeding the infused plastic material into a hopper of an injection molding machine. The methods may comprise forming the material for repelling lice by injection molding of the infused plastic material.

Abstract: A metal-toothed comb is provided having elongated identical teeth each with a square cross-section along substantially the entire length, elongated edges of each tooth being slightly rounded, free ends of each of the teeth being slightly rounded, whereby the teeth are successively positioned juxtaposed in a common plane, with elongated edges of each tooth opposing one another, and the distance between the teeth being a constant 0.004 inch along the entire length of the gap therebetween, except for a relatively small portion proximate the distal ends of each tooth, which are tapered down to a rounded tip.

Abstract: A comb for removing lice and nits from animal and/or human hair is provided with two spaced apart rows of teeth, the teeth in each row being successively adjacent to and in close proximity to one another with tapered distal ends, respectively, the longitudinal centerlines of the teeth of one row being respectively aligned with the longitudinal centerlines of spaces between the teeth of the other row, and with the teeth of one row being longer than the teeth of the other row.
