The invention relates to a process for protecting the colour of artificially dyed keratin fibres with respect to washing and atmospheric agents, characterized in that it consists in applying at least:
a) a composition (B) comprising, in a cosmetically acceptable medium, at least one agent for protection against the effects of atmospheric agents, in particular the light,
b) and a composition (C) comprising, in a cosmetically acceptable medium, at least one zinc-based compound; it being possible for the composition (C) to be applied before or after dyeing of the keratin fibres, and the composition (B) being applied after dyeing of the keratin fibres.
The invention also relates to a process for dyeing keratin fibres, in particular human keratin fibres, and more particularly the hair, consisting in applying to said fibres at least:
(i) a direct dye composition (A) or an oxidation dye composition (A) in the presence of an oxidizing agent for a period of time sufficient to develop the colour,
(ii) a composition (B) as defined above,
(iii) a composition (C) as defined above;
it being possible for the composition (C) to be applied before or after the keratin fibre dyeing step, and the composition (B) being applied after the keratin fibre dyeing step.
本发明涉及一种保护人工染色角蛋白纤维在洗涤和大气因素方面的颜色的过程,其特征在于,至少应用以下物质:a)一种组合物(B),包括至少一种用于保护大气因素(特别是光线)影响的剂,以及在化妆品可接受介质中;b)一种组合物(C),包括至少一种基于锌的化合物,以及在化妆品可接受介质中。组合物(C)可以在染色角蛋白纤维之前或之后应用,而组合物(B)则在染色角蛋白纤维之后应用。本发明还涉及一种染色角蛋白纤维(特别是人类角蛋白纤维,尤其是头发)的过程,包括至少应用以下物质:(i)直接染料组合物(A)或氧化染料组合物(A),在氧化剂的存在下,为使颜色得以发展而进行一段时间的应用;(ii)如上所定义的组合物(B);(iii)如上所定义的组合物(C)。组合物(C)可以在染色角蛋白纤维步骤之前或之后应用,而组合物(B)则在染色角蛋白纤维步骤之后应用。
