Hair treatment method

Abstract

Present invention relates to a hair treatment method for setting hair style and its restyling including a step of application of an anhydrous spray on wet hair. The present invention is a method of treating hair comprising the step of 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 and (np) units of AO may be the same or not onto wet hair.

Claims

1. A method of setting a hair style, the method comprising setting (i) wet hair or (ii) wet hair that was washed with a cleansing composition and towel dried immediately before application of a substantially anhydrous composition into a hair style after applying the substantially anhydrous composition thereon, wherein the substantially anhydrous composition comprises one or more polymers according to the general structure ##STR00003## 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, wherein water content of the substantially anhydrous composition is less than 5% by weight, calculated to the total composition excluding propellant, wherein the substantially anhydrous composition comprises an organic solvent, selected from the group consisting of ethanol, propanol, isopropanol, acetone, n-pentane, isopentane and mixtures thereof, at a concentration in the range of 70 to 99.9% by weight, calculated to the total composition excluding propellant wherein application of the substantially anhydrous composition onto the hair comprises spraying the substantially anhydrous composition onto the hair before setting the hair into the hair style.

2. The method according to claim 1 further comprising blow-drying the hair while brushing the hair and setting the hair into the hair style after application of the substantially anhydrous composition.

3. The method according to claim 1 wherein the one or more polymers have an average molecular weight in the range of 50,000 to 1,000,000.

5. The method according to claim 1 wherein the substantially anhydrous composition comprises the one or more polymers at a concentration in the range of 0.1 to 30% by weight calculated to the total composition excluding propellant.

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

7. The method according to claim 1, wherein the substantially anhydrous composition comprises ethanol.

8. The method according to claim 6 wherein the weight ratio of the one or more polymers to the anionic polymer is in the range of 2:8 to 8:2.

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

10. The method according to claim 1 wherein the substantially 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 the total of aerosol composition.

11. The method according to claim 4 wherein the one or more polymers comprise a combination of an ethyleneoxy group and a propyleneoxy group.

12. The method according to claim 5 wherein the substantially anhydrous composition comprises the one or more polymers at a concentration in the range of 2 to 10% by weight calculated to the total composition excluding propellant.
