Abstract

A method for cosmetic treatment of a mesh of hair, the method, including abrading the hair mesh by mesh by using a composition having abrasive particles applied onto the mesh and manually exerting pressure along the mesh during passes, the number of passes over a mesh being greater than five passes, and applying a cosmetic treatment composition to the hair, before, after, and/or during abrasion of the hair.

1 . A method for cosmetic treatment of a mesh of hair, the method comprising:
 abrading the hair mesh by mesh by using a composition comprising abrasive particles applied onto the mesh and manually exerting pressure along the mesh during passes, the number of passes over a mesh being greater than five passes, and   applying a cosmetic treatment composition to the hair, before, after, and/or during abrasion of the hair.   
     
     
         2 . A method according to  claim 1 , wherein the hair-care composition includes abrasive particles of mean size greater than or equal to 50 μm and the abrasive particles having a mean size less than or equal to 500 μm. 
     
     
         3 . A method according to  claim 1 , wherein the hair-care composition comprises abrasive solid particles having a mean dimension greater than or equal to 50 μm. 
     
     
         4 . A method according to  claim 1 , wherein the hair-care composition comprises abrasive solid particles of mean dimension greater than or equal to 50 μm, the method including subjecting the hair to post-treatment, after treatment with the hair-care composition, the post-treatment being selected from applying a permanent wave, a straitening composition, a coloring composition, or a bleaching composition for hair. 
     
     
         5 . A method according to  claim 1 , comprising abrading the hair with a hair-care composition including abrasive solid particles of mean dimension greater than or equal to 50 μm, wherein the abrasive solid particles are at a content lying in the range 0.1% to 20%, and are of hardness greater than or equal to 3, on the Mohs scale. 
     
     
         6 . A method according to  claim 1 , wherein the application of the pressure is performed by a tangential motion parallel to the hair and a shear motion orthogonal to the hair. 
     
     
         7 . A method according to  claim 1 , wherein the abrasive particles are selected from the following:
 inorganic and/or metallic particles;   organic particles; and   mixed particles associating organic and inorganic compounds, and particles coated in the above compounds.   
     
     
         8 . A method according to  claim 1 , wherein the abrasive particles have hardness greater than or equal to 3 on the Mohs scale. 
     
     
         9 . A method according to  claim 1 , wherein the abrasive solid particles present a content lying in the range 0.1% to 20% by weight relative to the total weight of the composition. 
     
     
         10 . A method according to  claim 1 , wherein the treatment composition is selected from:
 compositions that modify the mechanical properties of hair,   emollient or penetration compositions,   compositions that modify the surface properties of hair,   compositions for restructuring the insides of hair, and   dyes that are direct or that act on oxidation.   
     
     
         11 . A method according to  claim 1 , wherein the hair is rinsed after the abrading.
