Hair treatment method

Abstract

A hair treatment method sets a hair style and/or its restyling comprising application of an anhydrous spray on wet hair. The method treats hair by applying a substantially anhydrous composition, comprising one or more polymers according to the general structure ##STR00001##
wherein A is a C2 to C6 alkylene group and n represents an average number of 5 to 1000 and p represents an average number of 5 to 100, onto wet hair.

Claims

1. A method of styling hair, the method comprising: applying an anhydrous composition onto hair that is wet, wherein the anhydrous composition comprises: 1 to 15% by weight, calculated to a total of the anhydrous composition excluding propellant, of a polymer according to the general structure ##STR00003## and wherein A is a C.sub.2 to C.sub.6 alkylene group and n represents an average number of 5 to 1000 and p represents an average number of 5 to 100; and 80 to 99% by weight, calculated to the total of the anhydrous composition excluding propellant, of an organic solvent selected from the group consisting of ethanol, propanol, isopropanol, acetone, n-pentane, isopentane, and mixtures thereof; and blow-drying while brushing the hair after application of the anhydrous composition.

2. The method according to claim 1, wherein the polymer has an average molecular weight in the range of 50,000 to 1,000,000.

3. The method according to claim 1, wherein the polymer according to the above general structure consist of at least two alkyleneoxy groups or a combination of an ethyleneoxy group and a propyleneoxy group.

4. The method according to claim 1, wherein the polymer is present at a concentration in the range of 2 to 10% by weight, calculated to the total anhydrous composition excluding propellant.

5. The method according to claim 1, wherein the anhydrous composition further comprises an anionic polymer at a concentration in the range of 0.5 to 20% by weight, calculated to the total anhydrous composition excluding propellant.

6. The method according to claim 1, wherein the organic solvent is ethanol.

7. The method according to claim 1, wherein the hair is washed with a cleansing composition before application of the anhydrous composition.

8. The method according to claim 5, wherein the weight ratio of the polymer to the anionic polymer is in the range of 2:8 to 8:2.

9. The method according to claim 1, wherein the anhydrous composition comprises at least one oil at a concentration in the range of 0.01 to 10% by weight, calculated to the total anhydrous composition excluding propellant.

10. The method according to claim 1 wherein the anhydrous composition is an aerosol composition and comprises at least one propellant at a concentration in the range of 1 to 95% by weight, calculated to a total of the aerosol composition.

11. A kit for styling hair, the kit comprising: a brush and/or a comb; and the anhydrous composition according to claim 1.
