Treatment of keratin fibers, preferably capillaries, comprises applying a washing composition, rinsing, and drying or leaving to dry the fibers, where the fibers have undergone coloring process with styryl or imine compounds

摘要

Treatment of keratin fibers, which is previously undergone coloring process comprising providing at least one dye composition and drying the composition comprising styryl or imine compounds (I) and its addition salts, in a coloring medium, comprises applying a washing composition, rinsing and drying or leaving to dry the fibers, where the treatment is carried out in the presence of one or more inorganic acids, one or more organic acids, monovalent salts and/or their precursors, and one or more zinc salts or their mixtures. Treatment of keratin fibers, which is previously undergone coloring process comprising providing at least one dye composition and drying the composition comprising styryl or imine compounds of formula (I) and its addition salts, in a coloring medium, comprises applying a washing composition, rinsing and drying or leaving to dry the fibers, where the treatment is carried out in the presence of one or more inorganic acids, one or more organic acids, monovalent salts and/or their precursors, and one or more zinc salts or their mixtures.
