Abstract
A method for dyeing keratinous fibers, in particular, human hair, in which, after a thickened pre-treatment agent (M1) containing no oxidation dye precursors has been applied and allowed to react, a coloring agent (M2) is applied and allowed to react immediately thereafter and without rinsing. By carrying out said method, hair can be colored in a dyeing step and simultaneously multi-tonal dyeing with highlights or lowlights can be achieved.
