The subject matter of the present disclosure is a method for blonding and/or lightening keratinous fibers, which permits a multi-tone coloration with lighter (“highlights”) sections (strands) to be produced, wherein the use of solid, flat separating aids, more particularly from solid materials, such as aluminum, paper or Styrofoam and similar materials, is not required. In addition, an entire keratinous fiber ensemble can be blonded and/or lightened, wherein the release of ammonia and the drying of the blonding or lightening agent are reduced.
