A method for removing lice eggs from the hair of an infested human or animal using a nit-visualizing composition. 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.

L'invention se rapporte à un procédé de retrait d'oeufs de poux des cheveux d'un humain infesté ou des poils d'un animal à l'aide d'une composition permettant de visualiser ces oeufs. Ledit procédé consiste à utiliser certains colorants qui possèdent une affinité pour la surface des oeufs, de manière qu'une seconde personne puisse repérer plus facilement les oeufs et les retirer en peignant ou en utilisant une autre technique de retrait. Dans ce but, une substance colorée est dispersée dans un solvant à base d'eau ou d'alcool et, dans une réalisation, également dans un agent propulseur. La composition doit être appliquée sur les cheveux de l'humain infesté ou sur les poils de l'animal, puis retirée après le séchage, par brossage ou lavage. La substance colorée, qui est adsorbée par l'exosquelette chitineux et le ciment de liaison des oeufs de poux, reste sur les poux, ce qui facilite le repérage visuel et le retrait des oeufs de poux des cheveux ou des poils.
