The composition involves the use of certain dyes which have an affinity to the surface of nits, to thereby enable a second individual to more easily see and remove the eggs during a combing or other removal process. To effectuate this purpose, a colored material is dispersed within a water- or alcohol-based solvent and, in one embodiment, a liquefied propellant as well. The composition is applied to the hair of the infested human or animal, and then removed after drying by a process of brushing or washing. However, the colored material which adsorbs to the chitinous exoskeleton and binding cement of the lice eggs remains on the nits, thereby facilitating visual identification and removal of the lice eggs from hair.Other References
