Abstract
In brief, the present invention is directed to a method for conditioning hair which comprises: PA1 (a) applying to hair a leave-on composition comprising: PA2 (1) a nonvolatile, silicone conditioning agent; PA2 (2) a resin; and PA2 (3) a carrier; PA1 (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 ug silicone/1 g of hair.
