An aerosol hairspray product for styling and/or shaping hair wherein the product comprises: i. a container comprising a container wall which encloses a reservoir for storing a hairstyling formulation and a propellant, ii. the hairstyling formulation comprising: (a) at least about 50% water by total weight of the hairstyling formulation and propellant; and (b) from about 0.01% to about 20% of a hairstyling polymer by total weight of the hairstyling formulation and propellant; and iii. a compressed gas propellant; and iv. a spraying device attached to the container for dispensing the hairstyling formulation, the spraying device comprising: (a) a spray nozzle for atomizing the hairstyling formulation, said nozzle defining an axial direction and having a longitudinal axis (L-L) therethrough; (b) at least one discrete inlet port, said inlet port having an associated inlet area, said inlet port not circumscribing said longitudinal axis (L-L) and being radially offset therefrom; (c) a flow area joining said inlet port and said nozzle, said flow area comprising a surface of revolution about said longitudinal axis (L-L), said surface of revolution convergently directing flow from said at least one inlet port to said nozzle; wherein at least a portion of the surface of revolution circumscribing said longitudinal axis (L-L) is curvilinear; and wherein the product is substantially free of alcohol, or is substantially free of ethanol and/or propanol. i. a container comprising a container wall which encloses a reservoir for storing a hairstyling formulation and a propellant, ii. the hairstyling formulation comprising: (a) at least about 50% water by total weight of the hairstyling formulation and propellant; and (b) from about 0.01% to about 20% of a hairstyling polymer by total weight of the hairstyling formulation and propellant; and (a) at least about 50% water by total weight of the hairstyling formulation and propellant; and (b) from about 0.01% to about 20% of a hairstyling polymer by total weight of the hairstyling formulation and propellant; and iii. a compressed gas propellant; and iv. a spraying device attached to the container for dispensing the hairstyling formulation, the spraying device comprising: (a) a spray nozzle for atomizing the hairstyling formulation, said nozzle defining an axial direction and having a longitudinal axis (L-L) therethrough; (b) at least one discrete inlet port, said inlet port having an associated inlet area, said inlet port not circumscribing said longitudinal axis (L-L) and being radially offset therefrom; (c) a flow area joining said inlet port and said nozzle, said flow area comprising a surface of revolution about said longitudinal axis (L-L), said surface of revolution convergently directing flow from said at least one inlet port to said nozzle; wherein at least a portion of the surface of revolution circumscribing said longitudinal axis (L-L) is curvilinear; (a) a spray nozzle for atomizing the hairstyling formulation, said nozzle defining an axial direction and having a longitudinal axis (L-L) therethrough; (b) at least one discrete inlet port, said inlet port having an associated inlet area, said inlet port not circumscribing said longitudinal axis (L-L) and being radially offset therefrom; (c) a flow area joining said inlet port and said nozzle, said flow area comprising a surface of revolution about said longitudinal axis (L-L), said surface of revolution convergently directing flow from said at least one inlet port to said nozzle; wherein at least a portion of the surface of revolution circumscribing said longitudinal axis (L-L) is curvilinear;
