A pre-treatment solution for use in oxidatively dyeing hair comprises an aqueous solution of a complex of a transition metal ion, especially copper-II, and a chelating agent selected from 2,2′-dipyridyl and o-phenanthroline.
A pretreatment process with this solution serves to conform the oxidative dyeing rate of virgin hair to that of the normally noncongruent rate of nonvirgin hair, so as to enhance the efficiency of the oxidative dyeing process, without reducing the intensity or variety of color. A hair treatment package in kit form comprising the aqueous solution and an oxidative hair dye mixture is also disclosed.
一种用于氧化染发的预处理溶液包括过渡金属离子(尤其是铜Ⅱ)与选自 2,2′-二吡啶基和邻菲罗啉的螯合剂的络合物的水溶液。
用这种溶液进行预处理,可使原生发的氧化染色速率与非原生发的通常不一致的速率相一致,从而提高氧化染色过程的效率,而不降低颜色的强度或种类。此外,还公开了一种试剂盒形式的头发处理包,其中包括水溶液和氧化染发混合物。
