The Nit-Free Terminator Comb is the best comb to remove hair lice and nits. The Micro-Grooving consists of microscopic cutting edges that are positioned along the teeth in a tight spiral form. With thorough combing, these cutting edges, together with the dragging action of the teeth, remove even the tiniest nit.This comb can be used alone or for more thorough care, use with any hair lice treatment product such as Nit-Free Mousse.
