A process for dyeing human keratin fibers with a lightening effect, comprising:
- a) applying to human keratin fibers having a tone height of less than or equal to 6 a cosmetic composition comprising, in a cosmetically acceptable medium, at least one fluorescent dye that is soluble in the medium and at least one aminosilicone;
- with the proviso that the fluorescent dye is not 2-[2-(4-dialkylamino)phenylethenyl]-1-alkylpyridinium wherein the alkyl radical of the pyridinium nucleus is chosen from methyl and ethyl radicals and wherein the alkyl radical of the benzene nucleus is chosen from methyl radicals, and wherein the counterion is a halide, for a time that is sufficient to develop the desired coloration and lightening,
- b) optionally rinsing the fibers,
- c) optionally washing the fibers with shampoo and rinsing,
- d) drying the fibers are or leaving the fibers to dry.
(canceled)
A process for dyeing human keratin fibers with a lightening effect, comprising:
- a) separately storing a composition comprising, in a cosmetically acceptable medium, at least one fluorescent dye that is soluble in the medium and at least one aminosilicone, and optionally at least one oxidation base and optionally at least one coupler;
- with the proviso that the fluorescent dye is not 2-[2-(4-dialkylamino)phenylethenyl]-1-alkylpyridinium wherein the alkyl radical of the pyridinium nucleus is chosen from methyl and ethyl radicals and wherein the alkyl radical of the benzene nucleus is chosen from methyl radicals, and wherein the counterion is a halide,
- and separately storing another composition comprising, in a cosmetically acceptable medium, at least one oxidizing agent,
- b) mixing the separately stored compositions together at the time of use, and applying the resulting mixture to human keratin fibers having a tone height of less than or equal to 6, for a time that is sufficient to develop the desired coloration and lightening,
- c) optionally rinsing the fibers,
- d) optionally washing the fibers with shampoo and rinsing,
- e) drying the fibers or leaving the fibers to dry.
