Abstract
Described herein is a method for shaping keratin fibres including (i) providing a crosslinking composition, wherein the crosslinking composition includes a 2-oxazolidinone compound, a photocatalyst being a hydroxy-substituted aromatic compound, and a cosmetically acceptable carrier; (ii) applying the crosslinking composition to keratin fibres; and (iii) mechanically shaping the keratin fibres with an appliance at a temperature of from about 80° C. to about 180° C. while exposing the crosslinking composition to electromagnetic radiation having a wavelength of from about 300 nm to about 750 nm.
