PROBLEM TO BE SOLVED: To provide a non-aqueous hair dye to be applied to the hair by mixing an aqueous cream hair dye and an oxidant at the time of use which dyes hair brightly, and which has a good hair dyeing efficacy.SOLUTION: A hair dye is used by mixing a non-aqueous cream hair dye and an oxidant composition containing a hydrogen peroxide of at least not less than 4.5% in the ratio of 1:1-1:3 at the time of use. The non-aqueous cream hair dye contains the following component (a)-(c): (a) 10-20 mass% of an anhydrous sodium metasilicate (b) 3-15 mass% of one or two or more kinds of anhydrous ammonium salts of inorganic acids or organic acids and (c) 0.01-0.5 mass% of an oxidation dye.COPYRIGHT: (C)2015,JPO&INPIT【課題】本発明は、水系クリ-ム状染毛剤と酸化剤を使用時に混合して毛髪に塗布せしめ、毛髪を高明度で、かつ良好な染毛効果を有する、非水系の染毛剤を提供するものである。【解決手段】非水系クリ-ム状染毛剤と過酸化水素を少なくとも4.5%以上含有する酸化剤組成物を1:1~1:3の混合比率で使用時に混合して使用する染毛剤であって、非水系クリ-ム状染毛剤が下記成分(a)~(c)を含有することを特徴とする染毛剤。(a)無水メタ珪酸ナトリウムを10~20質量%(b)無機酸または有機酸の無水アンモニウム塩類1~2種以上を3~15質量%(c)酸化染料を0.01~0.5質量%【選択図】なし
