Brush and method for treating the hair

Abstract

The invention relates to a method for treating the hair with a treatment device. in particular a brush ( 10 ), having:—a step of simultaneously heating and combing a lock of hair by passing it between teeth ( 23 ) of at least one heated combing zone (C) without a steam outlet of the treatment device, and—the application of steam to the lock of hair in at least one steam outlet zone (V), the step of simultaneous heating and combing and the application of steam being carried out on a lock of hair by passing the treatment device through the hair once.

1 - 14 . (canceled) 
     
     
         15 . A method for treating the hair with a treatment device, the method comprising:
 (i) simultaneously heating and combing a lock of hair between teeth of at least one heated combing zone without a steam outlet of the treatment device; and   (ii) applying steam to the lock of hair in at least one steam outlet zone,   wherein the steps of (i) and (ii) are carried out on the lock of hair by passing the treatment device through the hair at least once.   
     
     
         16 . The method of  claim 15 ,
 wherein the method comprises two steps of (i),   wherein one step (i) is carried out before step (ii) and one step (i) is carried out after step (ii), and   wherein the two steps (i) and one step of (ii) are carried out on the lock of hair by passing the treatment device through the hair at least twice.   
     
     
         17 . The method of  claim 16 , wherein in the two steps of (i), the treatment device is passed through the hair at a substantially constant speed. 
     
     
         18 . The method of  claim 15 ,
 wherein the treatment device comprises a treatment surface, and the teeth extend from the treatment surface in the heated combing zone,   wherein the heating in step (i) is carried out by:   a) thermal transmission from the treatment surface heated by heating means of the treatment device; or   b) thermal transmission from at least some of the teeth of the at least one heated combing zone without a steam outlet, and   wherein the combing in step (i) is carried out by passing the teeth in the heated combing zone.   
     
     
         19 . The method of  claim 15 , wherein the at least one heated combing zone comprises:
 a) teeth comprising at least one heat conducting material, and   b) teeth comprising at least one heat insulating material.   
     
     
         20 . The method of  claim 19 , wherein the teeth comprising at least one heat conducting material in the at least one heated combing zone are heated by the heating means of the treatment device by thermal radiation emitted from the heating means. 
     
     
         21 . The method of  claim 19 , wherein the heat insulating material is an elastomer or a plastic. 
     
     
         22 . The method of  claim 15 , wherein the at least one heated combing zone comprises:
 a) a plurality of rows of teeth comprising at least one heat conducting material, and   b) a plurality of rows of teeth comprising at least one heat insulating material.   
     
     
         23 . The method of  claim 19 , wherein the total number of the teeth in the heated combing zone(s) made of the at least one heat insulating material ranges from 20% to 75%. 
     
     
         24 . The method of  claim 19 , wherein the length of the teeth comprising the at least one heat insulating material is at least 10% greater than a length of the teeth comprising the at least one heat conducting material in the heated combing zone. 
     
     
         25 . The method of  claim 15 , wherein step (ii) further comprises:
 simultaneously combing the lock of hair in the steam outlet zone.   
     
     
         26 . The method of  claim 22 ,
 wherein step (ii) is carried out through at least one row of steam outlets that extend in the at least one steam outlet zone,   wherein the steam outlets that extend in the at least one steam outlet zone alternate with the teeth in the at least one steam outlet zone.   
     
     
         27 . The method of  claim 15 , wherein, in each of the at least one heated combing zone adjacent to the steam outlet zone, a row of teeth closest to the steam outlet zone is made of at least one heat insulating material. 
     
     
         28 . The method of  claim 19 , wherein the teeth comprising the at least one heat insulating material have an elongated cross section. 
     
     
         29 . The method of  claim 15 , comprising applying a cosmetic product to the hair by a zone of the treatment device while the treatment device passes through the hair. 
     
     
         30 . A brush for treating the hair comprising:
 at least one heated hair combing zone, without a steam outlet, comprising a plurality of teeth wherein heating means are carried out for heating at least two teeth of the plurality of teeth; and   at least one steam outlet zone separate from the at least one heated hair combing zone.
