    • The present invention relates to a composition for keratin fibers, preferably hair, comprising (a) at least one cationic vinylpyrrolidone polymer; (b) at least one cationic cyclopolymer having at least one ring-structure in the backbone of the polymer; and (c) at least one oxidizing agent, wherein the (a) cationic vinylpyrrolidone polymer and the (b) cationic cyclopolymer are different from each other, and the weight ratio of (the amount of the (a) cationic vinylpyrrolidone polymer)/(the amount of the (b) cationic cyclopolymer) is 1.5 or more. The present invention can prevent or reduce the loss of volume of keratin fibers when the keratin fibers are colored by, for example, dyeing or bleaching, and when the colored keratin fibers are washed by, for example, shampooing.
    • 本发明涉及用于角蛋白纤维(优选头发)的组合物,其包含(a)至少一种阳离子乙烯基吡咯烷酮聚合物; (b)至少一种在聚合物骨架中具有至少一个环结构的阳离子环聚合物; 和(c)至少一种氧化剂,其中(a)阳离子乙烯基吡咯烷酮聚合物和(b)阳离子环聚合物彼此不同,((a)阳离子乙烯基吡咯烷酮聚合物的量/ (b)阳离子环状聚合物的量)为1.5以上。 本发明可防止或减少当角蛋白纤维通过例如染色或漂白而着色时以及当通过例如洗发洗涤着色的角蛋白纤维时角蛋白纤维的体积损失。
