PROBLEM TO BE SOLVED: To provide a hair cosmetic which can improve a feeling and an appearance of damaged hair into such hair that seems to be healthy, and can keep their effects without being spoiled even by repeated shampoo.SOLUTION: A hair cosmetic contains component (A) and (B). (A): a cationic polymer having a charge density of 5.0-7.0 meq/g. (B): an anionic polysaccharide derivative in which a part of H of -OH in a polysaccharide compound having a constitutional unit of a formula (1) is substituted by group-(CH)COO(m is an integer of 1-5) with average degrees of substitution of 0.5-2.0 per constitutional unit, a part of H of the remaining -OH may be substituted by the alkyl group and/or alkylene group of C, and the viscosity of a 2 mass% of aqueous solution (25°C) is 0.5-800 mPa s. [R' is an alkylene group of Cwhich may be substituted by -OH respectively； n is a number of 0-10 in an average addition mole number of R'O per constitutional unit.]【課題】傷んだ毛髪の感触及び外観を健康毛のように改善することができ、それらの効果を、繰り返しの洗髪によっても損なわれることなく持続させることができる毛髪化粧料の提供。【解決手段】成分(A)及び(B)を含有する毛髪化粧料。(A)電荷密度5.0～7.0meq/gのカチオン性ポリマー(B)式（１）の構成単位を有する多糖化合物の－ＯＨのＨの一部が、基－(ＣＨ2)mＣＯＯ-（ｍは1～5の整数）によって構成単位当たりの平均置換度0.5～2.0で置換されており、残りの－ＯＨのＨの一部がＣ1-40のアルキル基及び／又はアルキレン基で置換されていてもよく、2質量％水溶液（25℃）の粘度が0.5～800mPa・sであるアニオン性多糖誘導体〔Ｒ'は各々－ＯＨで置換されてよいＣ2-4のアルキレン基；ｎは構成単位当たりのＲ'Ｏの平均付加モル数が0～10となる数〕【選択図】なし
