Post oxidative hair treatment agent with silicone

A method for oxidative lightening and/or coloring of keratinic fibers, wherein

• 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,
• b) subsequently, within a time span from about one second to about 24 hours after step a), a post-treatment agent that contains at least one 4-morpholinomethyl-substituted silicone of formula (V),
• in which
• A denotes a structural unit (I), (II), or (III) bound via-0
• or an oligomeric or polymeric residue bound via —O— containing structural units of formulas (I), (II), or (III), or half of an oxygen atom connecting to a 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,
• is applied onto the keratinic fibers, in particular onto the hair.
