Abstract
Agent having at least one non-ionic component having an HLB of 8.0 or less are disclosed, as well as the combination of a blue and red substantive dye wherein the weight ratio of the blue dyes as opposed to the red dyes is 1 or greater. Further disclosed are agents for dyeing human hair blond having at least one oxidizing agent preparation and optionally a bleaching force reinforcing preparation. The agents make it possible to avoid undesired color shifts towards yellow or red nuances during blond hair dyeing.
