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.

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

14- A kit for hair comprising at least one hair appliance selected from a brush and a comb and a substantially anhydrous composition comprising one or more polymers according to the general structure ##STR00004## 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.
