Claim 15:
16. A method for providing keratin fibers with a wave or curl comprising:
a) applying onto the keratin fibers a composition comprising:
i. from 2 to 15% by weight, relative to the total weight of the composition, of at least one agent chosen from arginine, histidine, lysine, glycine, taurine, alanine, proline, 2-(cyclohexylamino)ethanesulfonic acid, or mixtures of two or more thereof;
ii. from 0.5 to 2% by weight, relative to the total weight of the composition, of at least one polymeric thickener chosen from cellulose, guar gum, xanthan gum, derivatives thereof, or mixtures of two or more thereof;
iii. optionally 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;
wherein the method does not include application of reducing agents or oxidizing agents;
b) heating the keratin fibers at a temperature ranging from 80° C. to 100° C.; and
c) optionally rinsing and/or drying the keratin fibers.
