Claim 8:
9. A method for reshaping keratin fibers comprising:
a) applying onto the keratin fibers a composition comprising:
i. from 0.5 to 20% by weight, relative to the total weight of the composition, of at least one organic acidic agent chosen from glycine, taurine, alanine, proline, 2-(cyclohexylamino)ethanesulfonic acid, or mixtures of two or more thereof;
ii. from 0.1 to 10% by weight, relative to the total weight of the composition, of at least one polymeric thickener;
iii. at least one alkaline agent, and
iv. at least 50% by weight, relative to the total weight of the composition, of water;

wherein the composition has a pH ranging from 9 to 11; and
wherein the composition is free of methionine;
b) heating the keratin fibers at 50° C. to 250° C. for 1 minute to 2 hours; and
c) optionally rinsing and/or drying the keratin fibers,
wherein the method does not include application of reducing agents.
