Abstract
A process for permanently reshaping keratin fibers is disclosed. The process may comprise a) placing the keratin fibers under mechanical tension by rolling keratin fibers on a tensioning device so as to form curls, b) applying a reducing composition to the keratin fibers, c) individually covering each tensioning device rolled with keratin fibers with a cover comprising at least one heat-insulating material, so as to form at least one closed space above the keratin fibers, d) heating the keratin fibers at a constant temperature, and e) entrapping heat and condensation from the heating of the keratin fibers within the closed space so as to maintain the closed space at a substantially uniform temperature throughout the closed space. The tensioning device and/or the cover may further include at least one heat source as part of the tensioning device and/or the cover.
