Procédé de déformation permanente des fibres kératiniques comprenant une étape dapplication dune composition de rinçage intermédiaire comprenant un sel de cation métallique monovalent ou un sel dammonium et un acide organique
Permanent deformation of keratin fibers, preferably hair, comprises: applying a reducer composition to reduce keratin disulfide bonds on the fibers applying a rinsing composition comprising a monovalent metal cation salt and/or ammonium salt, organic acid or salts not being one or the salts of organic acids present in the intermediary rinsing composition and fixing by oxidation, to reform the bonds, by applying an oxidizing composition on the fibers. Process of permanent deformation of keratin fibers, preferably hair, comprises: applying a reducer composition for reducing keratin disulfide bonds on the keratin fibers, where the keratin fibers being placed under mechanical tension before (preferred), during or after the application applying a rinsing composition comprising a monovalent metal cation salt and/or ammonium salt, organic acid or salts not being one or the salts of organic acids present in the intermediary rinsing composition, where the salts are not surfactants and fixing by oxidation, to reform the bonds, by applying an oxidizing composition on the fibers, where the process does not comprise rinsing with water between the application of the reducer composition step and the application of the intermediary rinsing composition step, nor between the application of the intermediate rinsing composition step and application of the oxidizing composition step.
