Abstract
A subject-matter of the invention is a process for the permanent deformation of the hair comprising the successive application of a reducing composition and then of a neutralizing composition, at least one of these compositions comprising at least one cationic polymer, in which, before the application of the reducing composition, a third separate composition, which is distinct from the reducing and neutralizing compositions and comprises at least one anionic polymer, is applied to the hair in a preliminary way. The hair is rinsed, preferably only after having applied the (or at least one of the) composition(s) comprising the cationic polymer(s).
