An aerosol type cosmetic hair preparation characterized in that a raw ethanol solution containing 0.1-15 mass% N-methacryloyloxyethyl-N,N-dimethylammonium a-N-methylcarboxybetaine/alkyl methacrylate copolymer and an aerosol propellant comprising a liquefied petroleum gas having an initial internal pressure as measured at 20°C of 0.15-0.2 MPa have been packed in such a mixing proportion that the raw ethanol solution/aerosol propellant ratio by mass is in the range of 40/60 to 50/50. Also provided is an aerosol type cosmetic hair preparation characterized in that a raw ethanol solution containing 0.1-15 mass% polyvinylcaprolactam and an aerosol propellant comprising a liquefied petroleum gas having an initial internal pressure as measured at 20°C of 0.15- 0.2 MPa have been packed in such a mixing proportion that the raw ethanol solution/aerosol propellant ratio by mass is in the range of 40/60 to 50/50. Based on the results of a detailed investigation made again on behaviors of hair-spray users, the hair sprays which can be comfortably used are provided.本發明為一種氣膠型毛髮化妝料，其特徵在於，以乙醇原液和氣膠噴射劑之混合質量比為乙醇原液/氣膠噴射劑=40/60~50/50之範圍填充著含有N-甲基丙烯醯氧乙基N,N-二甲基銨-α-N-甲基羧基甜菜鹼-甲基丙烯酸烷基酯共聚物之乙醇原液與初期內壓在20℃為0.15~0.2MPa之液化石油氣體所構成之氣膠噴射劑；且該共聚物之配合量於該原液及該噴射氣體的合計量中為0.1~15質量%。又，本發明係一種氣膠型毛髮化妝料，其特徵在於，以乙醇原液和氣膠噴射劑之混合質量比為乙醇原液/氣膠噴射劑=40/60~50/50之範圍填充著含有聚乙烯基己內醯胺之乙醇原液與初期內壓在20℃為0.15~0.2MPa之液化石油氣體所構成之氣膠噴射劑；且該共聚物之配合量於該原液及該噴射氣體的合計量中為0.1~15質量%。。本發明之目的係重新詳細地探討毛髮噴霧使用者的動作，並提供一種毛髮噴霧，其讓使用者可感覺良好地噴霧。
