Abstract

Method for treating hair comprising the application onto hair of polymeric layer(s) which can removed to a large extent or even totally in an easy manner upon request of the user by using oxidizing composition.

First claim

What is claimed is:

1. A method for treating hair comprising:
A) carrying out the following step:
i) applying a first composition comprising a first cationic polymer to a first portion of the hair, wherein the first cationic polymer is uncolored polyethyleneimine; and
B) applying an oxidizing composition comprising one or more oxidizing agent(s) to a second portion of the hair;
wherein the first and second portions have at least one first common area,
wherein A) further comprises:
ii) applying a second composition comprising a first anionic polymer(s) to a third portion of the hair, wherein the first anionic polymer is uncolored dextran sodium sulfate;
wherein the first, second and third portions have at least one first common area,
wherein at least one of steps i), ii) or B) further comprises the subsequent sub-step of:
washing and/or rinsing the hair,
wherein:
the first composition comprises a total concentration of cationic polymer ranging from 0.1 g/L to 100 g/L and/or
the second composition comprises a total concentration of anionic polymer ranging from 0.1 g/L to 100 g/L,
wherein the method comprises between steps A) and B):
a) carrying out the following sequence of steps:
a 1 ) applying a third composition comprising a second cationic polymer to a fourth portion of the hair, wherein the second cationic polymer is polyethyleneimine with Reactive Red 180 (PEI Red); and
a 2 ) applying a fourth composition comprising a second anionic polymer to a fifth portion of the hair, wherein the second anionic polymer is uncolored dextran sodium sulfate,
the fourth and the fifth portions of the hair having at least one second common area; and optionally
b) repeating step a) at least once.
