Abstract
Official abstract text for this publication.
Method for treating hair comprising the successive application onto hair of polymeric layers which can be removed to a large extent or even totally in an easy manner upon request of the user by using a composition having a pH less than 7.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for treating hair comprising: A) carrying out the following sequence of steps: 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 ii) applying a second composition comprising a first anionic polymer to a second portion of the hair; wherein the first, anionic polymer is uncolored dextran sodium sulfate: and B) applying a third composition having a pH ranging from 1 to 7 to a third portion of hair, wherein the first, second and third portions have at least one first common area 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 fourth 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 fifth 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.
