The purpose of present invention is to provide a hair cosmetic which has no feeling of collapse at the time of application and maintains viscosity and elasticity suitable for treating hair and scalp. Provided is a hair cosmetic has: (a) a cationic surfactant； (b) a higher alcohol； (c) 0.1 to 5 mass% of one or more co-surfactants selected from the group consisting of compounds represented by the following general formulas (I) to (V)； the molar ratio [(b) / (a)] of (b) the higher alcohol to (a) the cationic surfactant is in the range of 2.0 to 5.0.In the formula, R1 is an alkyl group having 8 to 12 carbon atoms, R2 and R3 are each independently a hydrogen atom or a methyl group, X is a hydrogen atom or a fatty acid residue, and n is an integer of 1 to 3.In the formula, R1 is an alkyl group having 8 to 12 carbon atoms, R2 to R4 are each independently a hydrogen atom or a methyl group, X is a hydrogen atom or a fatty acid residue, and n is an integer of 1 to 3.[formula 3] CH3(CH2)7CH=CH(CH2)7CH2O(CH2CH2O)nH (III)In the formula, n represents an integer of 1 to 5.In the formula, any one of X1 to X4 is a hydrogen atom, and the other three are each independently a fatty acid residue having 8 to 22 carbon atoms.In the formula, X1 and X2 are each independently a fatty acid residue having 12 to 22 carbon atoms and n is an integer of 5 to 12.本發明提供一種毛髮化妝料，係無塗佈時的崩壞感且維持適合處理毛髮、頭皮之黏性及彈性。本發明關於一種毛髮化妝料，係包含：(a)陽離子性界面活性劑、(b)高級醇、及(c)0.1至5質量%之選自由下述通式(I)至(V)所示之化合物所成群組之1種以上之助界面活性劑，其中，上述(b)高級醇對(a)陽離子性界面活性劑之莫耳比[(b)/(a)]在2.0至5.0之範圍內； (式中，R1係表示碳數8至12之烷基，R2及R3係分別獨立地表示氫原子或甲基，X係表示氫原子或脂肪酸殘基，n係表示1至3之整數)(式中，R1係表示碳數8至12之烷基，R2至R4係分別獨立地表示氫原子或甲基，X係表示氫原子或脂肪酸殘基，n係表示1至3之整數)CH3(CH2)7CH=CH(CH2)7CH2O(CH2CH2O)nH (III)(式中，n係表示1至5之整數)(式中，X1至X4中任一者係表示氫原子，其餘三者係分別獨立地表示碳數8至22之脂肪酸殘基)(式中，X1及X2係分別獨立地表示碳數12至22之脂肪酸殘基，n係表示5至12之整數)。
