PROBLEM TO BE SOLVED: To provide a method for permanently reshaping hair keratin fibers by which the volume of the hair can permanently be increased. SOLUTION: The method for permanently reshaping the hair keratin fibers comprises a step for setting the keratin fibers under tension, then a step for applying a reducing composition comprising in a cosmetically acceptable medium at least one reducing agent in an amount of 0.1-3 wt.% based on the total weight of the reducing composition onto the keratin fibers so as to reduce the keratin disulfide bonds, then, after an optional rinsing operation, a step for drying the keratin fibers, then an oxidation fixing step so as to reform the bonds, by applying an oxidizing composition onto the keratin fibers. The reducing composition comprises at least one reducing agent selected from the group consisting of a sulfite, a hydrogensulfite, thiols and phosphines in the cosmetically acceptable medium.
