    • The invention relates to a method for dyeing keratin fibers, especially human hair. The inventive method comprises the following steps: optionally applying a pretreatment agent M1 to the fiber, using a dye M2 on the fiber which is optionally mixed immediately before application to the fiber from a component M2a, containing at least one oxidative dye pre-product of the developer type and/or an indole and/or indole derivative and a component M2b, containing an oxidative dye and/or an enzyme. If desired, a third agent M3 is added to the individual agents M2a or M2b before mixing them or to the mixture M2, and said dye M2 is rinsed from the fiber after a period of 5-30 minutes. At least one of the agents M1, M2a, M2b or M3 contains a compound from the vitamin B6 group. The invention further relates to hair pretreatment agents, to agents for dyeing keratin fibers, to their packing in corresponding kits and to the use thereof. The inventive compounds of the vitamin B6 group and their physiologically acceptable salts are useful as coupling components in the production of oxidative dyes that contain conventional developer and/or coupling compounds and/or indole and/or indole derivatives in a substrate appropriate for dyeing. The inventive compounds are further useful as active substances that improve the hair structure.
    • 本发明提供了一种用于染色角蛋白纤维,特别是人的头发,其中,如果需要,一个预处理装置(M1)被施加到纤维上,然后将着色剂(M2)发生在使用,任选立即应用程序之前,所述纤维 从一个组分,其包含所述显影剂的类型和/或吲哚中的至少一种氧化染料前体纤维(M2A)和/或吲哚啉衍生物和组分(M2b的)含有氧化剂和/或酶进行混合,如果需要的话, 个别装置(M2A)或(M2b型)混合或加入的混合物(M2)的另一装置(M3),该着色剂(M2)之前的从纤维5-30分钟的时间后退绕,其特征在于至少一个 包括装置(M1,M2A,M2b的或M3)从维生素B6组中的至少一种化合物。 本发明的另一个目的是一种毛发预处理剂,用于染色角蛋白纤维,和它们在相应的试剂盒和其用途的包装。 维生素B6组的和新化合物及其生理上可接受的盐是作为用于生产氧化着色剂与常规的开发者和/或成色剂化合物和/或吲哚和/或二氢吲哚衍生物在适当的染色介质中的内容耦合部件是有用的。 此外,本发明的化合物作为用于改善毛发结构剂。
