Method for reshaping in particular for smoothing keratin-containing fibers, in particular human hair in which (i) a pretreatment agent is applied to the keratinic fibers and left there which contains based on its weight 0.01 to 5% by weight preferably 0.025 to 2.5% by weight, more preferably 0.05 to 1.5% by weight, even more preferably 0.075 to 1% by weight and in particular 0.1 to 0.25% by weight of at least one 4-morpholinomethyl-substituted silicone of formula: where A stands for a structure bound by an -O- or an oligomeric or polymeric radical bound by an -O- and containing structural units of formula, or it stands for -OH, * stands for a bond to one of the structural units (i), (ii) or (iii) or for an end group B (bound by Si) or D (bound by O), B stands for a group -OH, -O-Si(CH 3) 3, -O-Si(CH 3) 2 OH, -O-Si(CH 3) 2 OCH 3, D stands for a group -H, -Si(CH 3) 3, -Si(CH 3) 2 OH, -SI(CH 3) 2 OCH 3, a, b and c stand for integers between 0 and 1000, with the provision that a + b + c > 0 m, n and o stand for numbers between 0 and 1000, with the provision that at least one of the conditions B = -OH and/or D = -H is satisfied; (ii) after a treatment time, the fibers - are not rinsed, - are optionally dried, (iii) the fibers are treated with an alkaline remodeling agent, (iv) the fibers are optionally rinsed, (v) the fibers are optionally shaped mechanically under the influence of heat.
