PROBLEM TO BE SOLVED: To provide a hairdressing agent composition that has excellent hairdressing properties (hair-raising power and hair-bundling feeling), low stickiness, and little flaking.SOLUTION: A hairdressing agent composition has emulsion-polymerized resin particles of acrylic monomers (A) and silica (B). An average particle diameter L(A) of the emulsion-polymerized resin particles of acrylic monomers (A) and an average particle diameter L(B) of the silica (B) are lower than or equal to 1000 nm, with the ratio between them, L(A)/L(B), of 1/2-100/1.SELECTED DRAWING: None【課題】整髪性（立ち上げ力、毛束感）に優れ、ベタツキが少なく、かつ、フレーキングが非常に少ない整髪剤組成物を提供する。【解決手段】アクリル系モノマーの乳化重合樹脂粒子（Ａ）とシリカ（Ｂ）を含有し、アクリル系モノマーの乳化重合樹脂粒子（Ａ）の平均粒子径Ｌ（Ａ）とシリカ（Ｂ）の平均粒子径Ｌ（Ｂ）が１０００ｎｍ以下であって、その比率Ｌ（Ａ）／Ｌ（Ｂ）が１／２～１００／１である整髪剤組成物とする。【選択図】なし
