The subject matter of the present invention is a method for oxidative lightening and/or coloring of keratinic fibers, in particular of hair, wherein
a) a pretreatment agent that contains at least one 4-morpholinomethyl-substituted silicone of formula (V) is applied onto the keratinic fibers, in particular onto the hair,b) subsequently, within a time span from one second to 24 hours after step a), a coloring and/or lightening agent is applied onto the keratinic fibers, which agent is obtained by mixing a composition (A) that contains at least one alkalizing agent with a composition (B) that contains, in a cosmetic carrier, at least one oxidizing agent,
where the composition (B) contains at least one acylpyridinium derivative of formula (Acylpyr-I),

1. A method for oxidative lightening and/or coloring of keratinic fibers comprising the steps of:
a) applying onto the keratinic fibers a pretreatment agent that contains at least one 4-morpholinomethyl-substituted silicone of formula (V), in whichA denotes a structural unit (I), (II), or (III) bound via —O— or an oligomeric or polymeric residue, bound via —O—, containing structural units (I), (II), or (III), or half of a connecting oxygen atom to the structural unit (III), or denotes —OH,* denotes a bond to one of the structural units (I), (II), or (III), or denotes a terminal group B (Si-bound) or D (O-bound),B denotes an —OH, —O—Si(CH3)3, —O—Si(CH3)2OH, —O—Si(CH3)2OCH3 group,D denotes an —H, —Si(CH3)3, —Si(CH3)2OH, —Si(CH3)2OCH3 group,a, b, and c denote integers from 0 to 990, with the provision that a+b+c>0,m, n, and o denote integers from 1 to 990. b) subsequently, within a time span from about one second to about 24 hours after step a), applying a coloring and/or lightening agent onto the keratinic fibers, which coloring and/or lightening agent is obtained by mixing a composition (A) that contains at least one alkalizing agent with a composition (B) that contains, in a cosmetic carrier, at least one oxidizing agent, wherein the composition (B) contains at least one acylpyridinium derivative of formula (Acylpyr-I),in which
R1 denotes a C1 to C6 alkyl group, a C2 to C6 alkenyl group, a C2 to C6 hydroxyalkyl group, a C1 to C6 alkoxy-C2 to C6 alkyl group, a carboxy C2 to C6 alkyl group, an aryl C1 to C6 alkyl group, a heteroaryl C1 to C6 alkyl group, an aryl group, or a heteroaryl group, R2, R3, and R4 mutually independently in each case denote hydrogen, a C1 to C6 alkyl group, a halogen atom, or a C1 to C6 acyl group, with the provision that at least one of the residues R2, R3, and R4 denotes a C1 to C6 acyl group, and X− denotes a physiologically acceptable anion.
