Composition (I) comprising an aminoethylaminoalkyl silicone (II) is used for pre- or post-treatment of human keratinic fibers before or after bleaching, where the alkyl group in (II) has 4-8 carbon atoms. An Independent claim is also included for bleaching human keratinic fibers by either: (a) applying (I) to the wet or dry (un)washed fibers, allowing (I) to act at room temperature or above, optionally rinsing the fibers, applying a bleaching composition, and washing, rinsing and drying the fibers; or (b) applying a bleaching composition, allowing it to act, shampooing and rinsing the fibers, applying (I), allowing (I) to act at room temperature or above, and optionally rinsing and drying the fibers.
