Method for lightening keratin materials using the coloring agent and the dye composition comprises an external cationic charge, containing a thiol / disulfide fluorescent colorant comprising been interrupted (interrupted) alkylene chain

摘要

Using said compositions and dyeing composition, comprising a pyridinium thiol / disulfide fluorescent colorant comprising an alkylene chain interrupted and external cationic charge, keratin materials, keratin fibers, the present invention is of human, such as hair in particular on colored method having the keratin fibers, the lightening effect. The present invention relates to thiol / disulfide fluorescent colorant of new, also its use for and lightening keratin materials. The composition makes it possible to provide a lightening effect visible particularly difficult to fall against a dark keratin fibers.
