Process for treating hair fibres

Abstract

The invention relates to a process for treating hair fibres, comprising (i) combing the hair fibres, (ii) applying a composition to the hair fibres, (iii) treating the hair fibres by applying steam, (iv) heat-treating the hair fibres by conduction and/or radiation, step (i) being carried out before step (ii).

1 . A process for treating hair fibres, comprising:
 (i) combing the hair fibres,   (ii) applying a composition to the hair fibres,   (iii) treating the hair fibres by applying steam,   (iv) heat-treating the hair fibres by conduction and/or radiation,   wherein the combing (i) is carried out before the applying (ii).   
     
     
         2 . The process according to  claim 1 , which is free of any combing step after the applying (ii) within a period of 15 s. 
     
     
         3 . The process according to  claim 1 , comprising a single combing step. 
     
     
         4 . A process for treating hair fibres, comprising:
 (i) a single step of combing the hair fibres,   (ii) applying a composition to the hair fibres,   (iv) heat-treating the hair fibres,   wherein the combing (i) is carried out before the applying (ii).   
     
     
         5 . The process according to  claim 4 , comprising (iii) treating the hair fibres by applying steam. 
     
     
         6 . The process according to  claim 1 , wherein the treating (iii) is carried out after the applying (ii) and before the heat-treating (iv). 
     
     
         7 . The process according to  claim 1 , wherein the combing (i) is carried out for less than 5 min before the applying (ii). 
     
     
         8 . The process according to  claim 1 , wherein the heat-treating (iv) is carried out after the applying (ii). 
     
     
         9 . The process according to  claim 1 , wherein steps of the process are carried out by at least two different tools. 
     
     
         10 . The process according to  claim 1 , wherein the combing (i) and the applying (ii) are carried out using a single tool. 
     
     
         11 . The process according to  claim 1 , wherein steps of the process are carried out using a single tool. 
     
     
         12 . The process according to  claim 9 , wherein steps of the process are carried out by moving the tools along a lock of hair fibres. 
     
     
         13 . The process according to  claim 1 , the heat treatment (iv) being carried out by contact of the hair fibres with hot surfaces. 
     
     
         14 . The process according to  claim 1 , the heat treatment (iv) being carried out at a temperature of 90° C. to less than 230° C. 
     
     
         15 . The process according to  claim 1 , wherein the composition is in the fluid state during the application (ii). 
     
     
         16 . The process according to  claim 6 , wherein the treating (iii) is carried out less than 5 min before the heat-treating (iv) and after the applying (ii). 
     
     
         17 . The process according to  claim 8 , wherein the heat-treating (iv) is carried out less than 5 min after the applying (ii). 
     
     
         18 . The process according to  claim 11 , wherein the single tool is a device for shaping the head of hair configured to carry out process steps successively in the same portion of hair fibres.
