A process for permanently modifying the shape of hair by wrapping hair in
multilayered, deformable sheets of material comprising a first layer of a
perforated, deformable, and semi-rigid material, and a second layer of
material containing a thiol reducing composition in an amount effective
for permanently modifying the shape of hair, wherein the first layer is
placed on or attached to the second layer; providing a desired shape to
the multilayered, deformable sheet of material which is wrapped around the
hair; and applying an oxidizing composition comprising an oxidizing agent
capable of reconstituting the disulfide bonds of the hair, wherein the
oxidizing composition is applied either before or after liberating the
hair from the multilayered, deformable sheet of material. In another
variation, the hair is pre-treated with the reducing composition and then
wrapped in a single deformable sheet for shaping. Multicomponent kits for
use in the processes of the invention.
