A method of treating the hair, the method comprising: a. providing a concentrated hair care composition in an aerosol foam dispenser, wherein the concentrated hair care composition comprises: i. from 4% to 20%, preferably from 4.5% to 15%, preferably from 5% to 10% of one or more silicones, by weight of the concentrated hair care composition, wherein the particle size of the one or more silicones is from 1 nm to 300 nm; ii. from 2% to 6% fatty alcohols, by weight of the concentrated hair care composition, wherein the fatty alcohols comprise stearyl alcohol and cetyl alcohol, and wherein the weight ratio of the stearyl alcohol to the cetyl alcohol is from 1.5:1 to 5:1; iii. from 1% to 10% propellant, by weight of the concentrated hair care composition; iv. from 0.5% to 7% perfume, by weight of the concentrated hair care composition; and v. from 75% to 95% water, by weight of the concentrated hair care composition; wherein the concentrated hair care composition has a liquid phase viscosity of from 200 centipoise to 15,000 centipoise; wherein the concentrated hair care composition has a silicone to high melting point fatty compound weight ratio of from 90:10 to 40:60; and wherein the concentrated hair care composition has a silicone to perfume weight ratio of from 98:2 to 50:50; b. dispensing the concentrated hair care composition from the aerosol foam dispenser as a foam; c. applying the foam to the hair; and d. rinsing the foam from the hair; wherein the foam has a density of from 0.025 g/cm 3 to 0.30 g/cm 3 when dispensed from the aerosol foam dispenser. a. providing a concentrated hair care composition in an aerosol foam dispenser, wherein the concentrated hair care composition comprises: i. from 4% to 20%, preferably from 4.5% to 15%, preferably from 5% to 10% of one or more silicones, by weight of the concentrated hair care composition, wherein the particle size of the one or more silicones is from 1 nm to 300 nm; ii. from 2% to 6% fatty alcohols, by weight of the concentrated hair care composition, wherein the fatty alcohols comprise stearyl alcohol and cetyl alcohol, and wherein the weight ratio of the stearyl alcohol to the cetyl alcohol is from 1.5:1 to 5:1; iii. from 1% to 10% propellant, by weight of the concentrated hair care composition; iv. from 0.5% to 7% perfume, by weight of the concentrated hair care composition; and v. from 75% to 95% water, by weight of the concentrated hair care composition; wherein the concentrated hair care composition has a liquid phase viscosity of from 200 centipoise to 15,000 centipoise; wherein the concentrated hair care composition has a silicone to high melting point fatty compound weight ratio of from 90:10 to 40:60; and wherein the concentrated hair care composition has a silicone to perfume weight ratio of from 98:2 to 50:50; i. from 4% to 20%, preferably from 4.5% to 15%, preferably from 5% to 10% of one or more silicones, by weight of the concentrated hair care composition, wherein the particle size of the one or more silicones is from 1 nm to 300 nm; ii. from 2% to 6% fatty alcohols, by weight of the concentrated hair care composition, wherein the fatty alcohols comprise stearyl alcohol and cetyl alcohol, and wherein the weight ratio of the stearyl alcohol to the cetyl alcohol is from 1.5:1 to 5:1; iii. from 1% to 10% propellant, by weight of the concentrated hair care composition; iv. from 0.5% to 7% perfume, by weight of the concentrated hair care composition; and v. from 75% to 95% water, by weight of the concentrated hair care composition; b. dispensing the concentrated hair care composition from the aerosol foam dispenser as a foam; c. applying the foam to the hair; and d. rinsing the foam from the hair; <EOS>
