    摘要: The present invention is directed to the provision of a kit-of-parts, a dyeing composition, and a method for dyeing keratin fibres. The kit comprises separate compositions A and B and optionally separate composition C. Composition A comprises a direct dye and an alkalising agent. The aqueous composition B comprises guanidine and/or its salts together with one or more lipophilic compounds and/or one or more thickening polymers. Composition C comprises a persalt and/or persulfate salt. A method for dyeing keratin fibres comprises mixing compositions A and B, and optionally C, to yield a ready-to-use composition with pH in the range of 7 to 12. Composition B may be used for enhancing colour intensity and/or wash fastness of a direct dye on keratin fibres with the provision that it is mixed with composition A directly prior to application.

    摘要: Processes and kits-of-parts reshape keratin fibers by applying a composition onto hair and covering the hair, wherein the composition comprises ammonia and one or more organic alkalizing agents. Additionally, the hair is put under tension using a curler with covering the curler with a moisture barrier, and heating the keratin fibers. As a result, long-lasting curl having cosmetic properties are achievable and an ammonia smell is reduced when directly compared to compositions having no organic alkalizing agent.
