Abstract

A method for treating hair comprising applying primer(s) and cationic polymer(s) onto a user's hair for improving the styling of the hair in a more manageable and reliable manner and for enhancing the stability of the final style obtained.

First claim

What is claimed is:

1. A method for styling hair comprising carrying out the following sequence of steps:
A) applying a first composition comprising one or more primers to a first portion of the hair to impart a surface of the hair with additional surface charges;
B) applying a second composition comprising one or more cationic polymers to a second portion of the hair, wherein the first portion and the second portion have at least one first common area; and
C) shaping the hair in at least part of the first common area.

2. The method according to claim 1 , further comprising between steps B) and C):
D) applying a third composition comprising one or more anionic polymers to a third portion of the hair, wherein the third portion has at least one second common area with the first common area.

3. The method according to claim 2 , further comprising:
repeating steps B) and D).

4. The method according to claim 2 , further comprising:
repeating step B).

5. The method according to claim 1 , further comprising prior to step A), or after steps A), B), C) or D):
applying a fourth composition to a fourth portion of the hair for at least one of washing or rinsing the hair, the fourth composition comprising a liquid selected from the group consisting of a cosmetically acceptable solvent, a solution comprising a cosmetically acceptable solvent and a cosmetically acceptable salt, a shampoo composition, and mixtures thereof,
wherein the fourth portion has at least one third common area with the first common area or the second common area.

6. The method according to claim 1 , wherein shaping comprises rearranging the hair to impart a given shape to the hair.

7. The method according to claim 1 , wherein step C) comprises straightening, spiking, curling, fixating, braiding, refreshing, touching-up, creating volume, creating texture, and combinations thereof.

8. The method according to claim 1 , wherein the one or more primers are selected from the group consisting of a cationic surfactant, an anionic surfactant, an amphoteric surfactant, an oxidizing agent, a reducing agent, a pH adjusting agent, and combinations thereof.

9. The method according to claim 1 , wherein at least one of the one or more cationic polymers or the one or more anionic polymers are uncolored, and wherein optionally no colored anionic or colored cationic polymer is applied to the hair after step A).

10. The method according to claim 1 , wherein the one or more cationic polymers are selected from the group consisting of polyethyleneimine, polyallylamine hydrochloride, polyvinylamine, copolymers thereof, and mixtures thereof.

11. The method according to claim 2 , wherein the one or more anionic polymers comprise one or more monomer units comprising one or more functional groups selected from the group consisting of sulfate, sulfonate, carboxylate, phosphate, phosphonate groups, and mixtures thereof.

12. The method according to claim 11 , wherein the one or more anionic polymers are selected from the group consisting of polystyrene sulfonate salts, λ-carrageenan salts, dextran sulfate salts, polyacrylic acid salts, poly(methacrylic acid) salts, alginic acid salts, carboxymethylcellulose salts, polystyrene sulfonate/polystyrene copolymer salts, polystyrene sulfonate/maleic acid copolymers salt, copolymers thereof, and mixtures thereof.

13. The method according to claim 1 , wherein at least one of:
the first composition comprises a total concentration of primers ranging from 0.1 g/L to 500 g/L; or
the second composition comprises a total concentration of cationic polymers ranging from 0.1 g/L to 100 g/L.
