In brief, the present invention is directed to a method for conditioning hair which comprises: (a) applying to hair a leave-on composition comprising: (1) a nonvolatile, silicone conditioning agent; (2) a resin; and (3) a carrier; (b) applying heat via a heating appliance to the composition treated hair to dry or style the hair and wherein a reduction in the bending modulus caused by the silicone conditioning agent is at least 1.00 %, even when offset by an increase in bending modulus caused by the presence of a resin, and wherein the method of the invention results in the deposition on the hair of at least 30 microgram silicone/1g of hair.

L'invention porte sur une méthode conférant une meilleure tenue aux cheveux. Cette méthode consiste à: (a) appliquer une composition sans rinçage comprenant: (1) un agent de conditionnement non volatil, au silicone, (2) une résine; et (3) un excipient; (b) appliquer de la chaleur au moyen d'un appareil diffusant de la chaleur sur les cheveux traités avec la composition de façon à les sécher ou les coiffer. La réduction du module de courbure induite par l'agent de conditionnement au silicone est d'au moins 1,00 %, même en cas de décalage créé par l'augmentation du module de courbure induite par la résine, cette méthode ayant pour résultat la formation d'un dépôt sur les cheveux d'au moins 30 microgrammes de silicone/1g de cheveux.
