Abstract[English]
The invention relates to a method for improving the fatigue resistance of keratin fibers, comprising applying a cosmetical composition to the keratin fibers, wherein the composition comprises epsilon-polylysine, and wherein the method improves the resistance of the keratin fibers against repeated tensile stress.[French]
L'invention concerne un procédé d'amélioration de la résistance à la fatigue des fibres de kératine, comprenant l'application d'une composition cosmétique sur les fibres de kératine, ladite composition comprenant de l'epsilon-polylysine, et ledit procédé améliorant la résistance des fibres de kératine contre les contraintes de traction répétées.
