Method for treating human keratinous fibers

Abstract

A method for cosmetic treatment of human keratinous fibers including the steps of: a) heating up in contact with or in the vicinity of a heating device, an outer surface of a piece of solid product, notably with hardness greater than or equal to 50 g at 20° C. so as to heat said piece in a localized way in order to only soften substantially said outer surface, and b) applying the thereby softened product on the fibers to be treated, notably the eyelashes

         18 . A method for cosmetic treatment of human keratinous fibers, comprising:
 a) heating up with contact to or in the vicinity of a heating device, an outer surface of a solid piece of product so as to heat said piece in a localized way with view to only substantially soften said outer surface, and   b) applying the thereby softened product on the fibers to be treated.   
     
     
         19 . The method according to  claim 18 , the temperature to which the outer surface is brought being greater than or equal to 40° C. 
     
     
         20 . The method according to  claim 18 , the piece of product having the shape of a stick. 
     
     
         21 . The method according to  claim 20 , the heated-up outer surface being defined by the distal end of the piece of product. 
     
     
         22 . The method according to  claim 20 , the heated-up outer surface being defined by at least one portion of the side surface of the piece of product. 
     
     
         23 . The method according to  claim 18 , the piece of product having a core remaining at a temperature less than or equal to 30° C. during the application, for a room temperature of 20° C. 
     
     
         24 . The method according to  claim 18 , the softened product being brought into contact with the keratinous fibers while the softened product is borne by the piece of product. 
     
     
         25 . The method according to  claim 18 , the softened product being brought into contact with the fibers after transfer of the softened product on a support used for the application. 
     
     
         26 . The method according to  claim 18 , the heating device heating at least one surface of a material other than the product used for the application. 
     
     
         27 . The method according to  claim 18 , the product comprising a volatile solvent. 
     
     
         28 . The method according to  claim 27 , the keratinous fibers being engaged in between protruding elements for combing the fibers during application of the product. 
     
     
         29 . A device for conditioning and applying a product intended for application on human keratinous fibers as a solid piece, the piece of product having a hardness greater than 45 g at 20° C., comprising:
 the piece of product, 
 a support of said solid piece of product, the latter having an outer surface; 
 means for assisting with application/finishing for, simultaneously with or after applying the product on the keratinous fibers, smoothing, combing and/or separating the latter, 
 a heating device which may be brought into contact with or in the vicinity of said outer surface for heating said piece in a localized way, in order to only substantially soften said outer surface. 
 
     
     
         30 . The device according to  claim 29 , the means for assisting with application/finishing including a row of protruding elements for combing the fibers. 
     
     
         31 . The device according to  claim 29 , the means for assisting with application/finishing being positioned or capable of being positioned in the vicinity of the outer surface. 
     
     
         32 . The device according to  claim 29 , the means for assisting with application/finishing being heated by the heating device. 
     
     
         33 . The device according to  claim 29 , the heating device being firmly attached to the piece of product during the use of the device for applying the product on the fibers.
