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).
Claims34
A process for the permanent deformation of the hair comprising applying to the full length of the hair a reducing composition (a) and then applying to the full length of the hair a neutralizing composition (b);
- wherein at least one of said compositions (a) and (b) comprises at least one cationic polymer;
- and wherein said process further comprises the application to the full length of the hair of a third composition (c), which is distinct from said compositions (a) and (b) and comprises at least one anionic polymer, before said application of the reducing composition (a) and at least one rinsing of the hair after having applied at least one composition comprising the cationic polymer.
A process for the permanent deformation of the hair comprising applying to the full length of the hair a reducing composition (a) and then applying to the full length of the hair a neutralizing composition (b), wherein said process further comprises the application to the full length of the hair of a third composition (c), which is distinct from said compositions (a) and (b) and comprises at least one anionic polymer, before said application of the reducing composition (a).
A kit for permanent waving of hair comprising a first separate compartment comprising a reducing composition (a) and a second separate compartment comprising a neutralizing composition (b), wherein at least one of said compositions comprises at least one cationic polymer and wherein said kit further comprises a third separate compartment comprising a third separate composition (c) comprising at least one anionic polymer, wherein said compositions (a), (b), and (c) are separately applied to the full length of said hair.
