Method of dyeing keratin materials comprising use of organosilicon compound, dyeing compound, sealant and pre-treatment agent

The invention relates to a method for dyeing a keratin material, in particular human hair, comprising the following steps:-applying an agent (v) to the keratin material, where the agent (v) comprises: (v) hydrogen peroxide,-applying an agent (a) to the keratin material, where the agent (a) comprises: (a1) at least one organosilicon compound selected from silanes having 1, 2 or 3 silicon atoms, and applying an agent (b) to the keratin material, where the agent (b) comprises: (b1) at least one sealant, where at least one of the agents (a) and (b) additionally comprises at least one dyeing compound selected from pigments and/or direct dyes. 本发明涉及一种对角蛋白材料、特别是人毛发染色的方法，其包括以下步骤：-将试剂(v)施用于所述角蛋白材料，其中试剂(v)含有：(v1)过氧化氢，-将试剂(a)施用于所述角蛋白材料，其中试剂(a)含有：(a1)至少一种选自具有1、2或3个硅原子的硅烷的有机硅化合物，和-将试剂(b)施用于所述角蛋白材料，其中试剂(b)含有：(b1)至少一种密封剂，其中试剂(a)和(b)中的至少一种另外含有至少一种选自颜料和/或直接染料的染色化合物。
