A hair treatment composition in a anionic, nonionic or amphoteric system includes water and a novel association of polysaccharide, such as inulin, and a film-forming polymer, such as polysilicone-29. The composition may include one or more additional components selected from polymers such as anionic polymers and nonionic polymers, amphoteric surfactants, or fatty compounds, embodied to deliver one or more of smoothing, straightening and curling/curl defining style features to achieve a particular straight or curly style with frizz control, softness and manageability.
