Abstract
A method for dyeing keratin fibers, in particular human hair, in which, after a thickened pretreatment agent (M1) including at least one oxidation dye precursor has been applied and left to act, directly thereafter and without rinsing a coloring agent (M2) is applied and left to act. By virtue of this method, in one dyeing step the hair can be colored and at the same time a multi-tonal dyeing with lighter ('highlights') or darker ('lowlights') sections (strands) can be produced.
