Hair treatment method and kit thereof
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 of at least 8.5.
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 haying a pH ranging from 8.5 to 14 to a third portion of hair, wherein the first, second and third portions have at least one first common area and wherein the third composition comprising at least one cationic surfactant oxidizing agent or reducing agent,
wherein:
the first composition comprises a total concentration of the first cationic polymer rangini from 0.1 g/L to 100 g/L and/or
the second composition comprises a total concentration of the first 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:
a1) appl ing 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
a2) 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.
