Abstract

A process for deforming keratin fibers involving: (a) mechanically deforming the keratin to form mechanically deformed keratin fibers; and (b) contacting the keratin fibers, prior to and/or after the keratin fibers are mechanically deformed, with an aqueous composition containing: (i) from about 0.1 to 20% by weight of an alkoxylated carboxylic acid ester; and (ii) from about 0.1 to about 20% by weight of a fatty acid partial glyceride, all weights being based on the weight of the composition.
