         45 . A method for cosmetic treatment of hair, the method comprising:
 abrading the hair using abrasion means enabling the hair to be abraded; and   applying a cosmetic treatment composition to the hair, before, after, and/or during abrasion of the hair.   
     
     
         46 . A method according to  claim 45 , wherein the hair is abraded by applying abrasive particles thereto, the abrasive particles being 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.   
     
     
         47 . A method according to  claim 46 , wherein the abrasive particles have hardness greater than or equal to 3 on the Mohs scale. 
     
     
         48 . A method according to  claim 45 , the abrasion means comprising at least two facing surfaces, at least one of which is abrasive, the facing surfaces being in contact with the hair during abrasion, and at least one of the facing surfaces acting on the hair by abrasion. 
     
     
         49 . A method according to  claim 48 , wherein only one surface is abrasive, the other surface(s) being non-abrasive. 
     
     
         50 . A method according to  claim 49 , wherein the non-abrasive surface is used to apply a treatment composition to the hair. 
     
     
         51 . A method according to  claim 48 , wherein the surfaces coming into contact with the hair are subject to motion relative to each other during the abrasion treatment, the relative motion being generally manually or at least in part in motor-driven manner, using a mechanical system. 
     
     
         52 . A method according to  claim 45 , wherein the abrasion means are configured in such a manner as to project abrasive particles onto the hair so as to abrade the hair. 
     
     
         53 . A method according to  claim 52 , wherein a jet of particles is propelled by a fluid. 
     
     
         54 . A method according to  claim 45 , wherein the abrasion means include a hair-care composition comprising abrasive particles that are applied to the hair so as to abrade it. 
     
     
         55 . A method according to  claim 45 , 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. 
     
     
         56 . A method according to  claim 54 , 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. 
     
     
         57 . A method according to  claim 45 , 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.   
     
     
         58 . A method according to  claim 45 , wherein the hair is rinsed after abrasion. 
     
     
         59 . A method according to  claim 45 , wherein the abrasion means include a hair-care composition comprising abrasive solid particles having a mean dimension greater than or equal to 50 μm, the abrasion treatment being performed mesh by mesh, the number of passes being greater than five passes. 
     
     
         60 . A method according to  claim 45 , wherein the abrasion means include a hair-care composition comprising 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. 
     
     
         61 . A hair treatment method comprising abrading the hair with a hair-care composition including abrasive solid particles of mean dimension greater than or equal to 50 μm, the method comprising subjecting the hair to post-treatment, after treatment with the hair-care composition, the post-treatment being selected from applying a permanent wave, a straightening composition, a coloring composition, or a bleaching composition for hair. 
     
     
         62 . A hair treatment kit comprising:
 abrasion means enabling the hair to be abraded; and   one or more cosmetic treatment compositions for hair.   
     
     
         63 . A hair treatment method 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. 
     
     
         64 . A hair treatment kit comprising, within a packaging device:
 a hair-care composition including abrasive solid particles of mean dimension greater than or equal to 50 μm, and   a medium including instructions for use of the hair-care composition on the hair for the purpose of abrading the hair.   
     
     
         65 . A kit according to  claim 64 , including a post-treatment composition for the hair, being selected from a conditioner, a permanent wave, a straightening composition, a coloring composition, or a bleaching composition for hair.
