    • The present invention concerns a process for oxidative coloring keratin fibers especially human hair wherein a pretreatment is applied onto hair prior to application of oxidative coloring agent. Accordingly, present invention is a process for oxidative dyeing of keratin fibers especially human hair wherein an aqueous composition comprising at least one inorganic salt catalyzing and/or effecting the oxidative color development reaction from oxidative dye precursors is applied onto wet or dry hair and optionally rinsed off, and subsequently an aqueous composition comprising at least one oxidative dye precursor, optionally at least one coupling agent and at least one oxidizing agent is applied onto hair and after processing of 5 to 45 min with or without use of heat, preferably at a temperature range between 20 and 45° C., rinsed off from hair.
    • 本发明涉及氧化着色角蛋白纤维,特别是人类头发的方法,其中在施用氧化着色剂之前将预处理施加到毛发上。 因此,本发明是一种对角蛋白纤维,特别是人类毛发进行氧化染色的方法,其中将包含至少一种催化和/或进行氧化染料前体的氧化显色反应的无机盐的水性组合物施用到湿或干燥的头发上并任选地漂洗 然后将包含至少一种氧化染料前体,任选的至少一种偶联剂和至少一种氧化剂的水性组合物施用到毛发上,并在加热或不使用加热,优选在温度下加热5至45分钟 范围在20和45℃之间,从头发冲洗出来。
