    • Disclosed are aerosol hair spray compositions which comprise a first and a second silicone-grafted copolymer, wherein the copolymers exhibit a dichotomous viscosity behavior which results in superior hold and excellent hair feel benefits, and a method of styling hair comprising applying to the hair an effective amount of the above composition. The aerosol hair spray compositions comprise: (A) from about 0.1% to about 10% by weight of said composition, of a first silicone-grafted copolymer comprising a vinyl polymeric backbone and a polysiloxane macromer grafted to said vinyl polymeric backbone, (i) wherein said first silicone-grafted copolymer is formed from the copolymerization of randomly repeating hydrophilic monomer units, herein designated A, and hydrophobic monomer units, herein designated B, (a) wherein said vinyl polymeric backbone comprises from about 10% to about 50%, by weight of said first silicone-grafted copolymer, of copolymerizable hydrophilic A monomers, (b) wherein said vinyl polymeric backbone comprises from 0% to about 85%, by weight of said first silicone-grafted copolymer, of copolymerizable hydrophobic B monomers, (c) wherein said polysiloxane macromer comprises from about 5% to about 50%, by weight of said first silicone-grafted copolymer, of polysiloxane-containing monomer units, (ii) wherein said polysiloxane macromer has a weight average molecular weight from about 500 to about 50,000; and (iii) wherein said first silicone-grafted copolymer has a weight average molecular weight from about 10,000 to about 500,000; (B) from about 0.1% to about 5% by weight of said composition, of a second silicone-grafted copolymer, comprising a vinyl polymeric backbone and a polysiloxane macromer grafted to said vinyl polymeric backbone, (i) wherein said second silicone-grafted copolymer is formed from the copolymerization of randomly repeating hydrophobic monomer units, herein designated B, (ii) wherein said polysiloxane macromer comprises from about 10% to about 40%, by weight of said second silicone-grafted copolymer, of polysiloxane-containing monomer units, (iii) wherein said polysiloxane macromer has a weight average molecular weight from about 5,000 to about 50,000, (iv) wherein said second silicone-grafted copolymer has a weight average molecular weight from about 300,000 to about 5,000,000, and (v) wherein said first silicone-grafted copolymer is present, relative to said second silicone-grafted copolymer, by weight, in a ratio from about 2:1 to about 26:1; (C) a neutralizing system, (D) from about 20% to about 50%, by weight of said composition, of a propellant; and (E) the balance comprising a carrier.
