Abstract

A method of treating the hair including providing a concentrated hair care composition in an aerosol foam dispenser. The concentrated hair care composition includes one or more silicones, perfume, and less than 10% high melting point fatty compounds. The method also includes dispensing the concentrated hair care composition from the aerosol foam dispenser as a dosage of foam; applying the foam to the hair; and rinsing the foam from the hair. The foam has a density of from about 0.025 g/cm³ to about 0.40 g/cm³ when dispensed from the aerosol foam dispenser.

Claims

1. 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 about 10% to about 14%, by weight of the concentrated hair care composition, of an aminopropylaminoethylpolysiloxane;

wherein the particle size of the aminopropylaminoethylpolysiloxane is from about 10 nm to about 60 nm;

ii. less than 8%, by weight of the concentrated hair care composition, of a mixture of cetyl alcohol and stearyl alcohol;

iii. from about 0.5% to about 4%, by weight of the concentrated conditioner composition, of a cetyl trimethyl ammonium chloride;

iv. from about 1% to about 12% propellant, by weight of the concentrated hair care composition;

v. from about 0.5% to about 7%, by weight of the concentrated hair care composition, of a perfume;

vii. from about 60% to about 90% 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.

2. The method of claim 1, wherein the concentrated hair care composition has a liquid phase viscosity of from about 200 centipoise to about 2000 centipoise.

3. The method of claim 1, wherein the concentrated hair care composition comprises from about 2% to about 12%, by weight of the concentrated hair care composition, of a nonionic emulsifier.

4. The method of claim 1, wherein the concentrated hair care composition comprises less than 6%, by weight of the concentrated hair care composition, of the mixture of cetyl alcohol and stearyl alcohol.

5. The method of claim 1, wherein the concentrated hair care composition comprises from about 1% to about 6%, by weight of the concentrated hair care composition, of the perfume.

6. The method of claim 1, wherein the foam has a dosage weight of from about 1 g to about 5 g when dispensed from the aerosol foam dispenser.

7. The method of claim 1, wherein the density of the foam is from about 0.035 g/cm³ to about 0.20 g/cm³.

8. The method of claim 1, further comprising the step of washing the hair with a shampoo before providing the concentrated conditioner.
