Claim Text:
1. A method for reshaping and/or straightening keratin-containing fibers, comprising: (i) applying a pretreatment agent including, relative to the weight thereof, 0.01 to 5 wt. % amino-functional silicone(s) with terminal hydroxyl group(s) onto the keratinic fibers, (ii) drying the fibers, (iii) treating the fibers in the dried state with a reshaping agent that, relative to the weight of the reshaping agent, includes 0.05 to 20 wt. % of guanidine and/or guanidinium salt(s), (iv) straightening the fibers with a comb or a brush during the reshaping treatment, (v) shampooing the fibers with a shampoo which has a pH of 2.5 to 6.5, followed by rinsing and neutralizing the fibers, and (vi) optionally subsequently mechanically deforming the fibers with exposure to heat, wherein the amino-functional silicone(s) is/are selected from the group consisting of formulas (I), (II), (III), and (IV): in which formula (II) being as follows in which formula (III) being as follows in which A denotes a group —OH, —O—Si(CH D denotes a group —H, —Si(CH b, n and c each denote integers between 0 and 1000, with the provisos at least one of the conditions A=—OH or D=—H is met; and formula (IV) being at least one 4-morpholinomethyl-substituted silicone as follows in which A denotes a structural unit (i), (ii) or (iii) attached via an —O— * denotes a bond to one of structural units (i), (ii) or (iii) or denotes an end group B (Si-bound) or D (O-bound), B denotes a group —OH, —O—Si(CH D denotes a group —H, —Si(CH a, b and c each denote integers between 0 and 1000, with the proviso a+b+c>0 m, n and o each denote integers between 1 and 1000, with the proviso that at least one of the conditions B=—OH or D=—H is met.
