Abstract

The invention discloses a method for shaping keratin fibres comprising: providing a crosslinking composition, wherein the crosslinking composition comprises: an active agent, wherein the active agent is a carbonate ester; and wherein the active agent has a molecular weight of 500 g / mol or less; a photocatalyst; a cosmetically acceptable carrier; and applying the crosslinking composition to keratin fibres, mechanically shaping the keratin fibres with an appliance at a temperature of from about 80 DEG C to about 180 DEG C and exposing the composition to electromagnetic radiation having a wavelength of from about 300 nm to about 750 nm. Also a related composition, use, kit and process are disclosed.

Description

technical field [0001] A method for shaping keratin fibers, the method comprising: providing a crosslinking composition, wherein the crosslinking composition comprises: an active agent, wherein the active agent is a carbonate; a photocatalyst; a cosmetically acceptable acceptable carrier; and applying the crosslinking composition to keratin fibers, mechanically shaping the keratin fibers using an appliance at a temperature of about 80°C to about 180°C, and exposing the composition to Electromagnetic radiation with a wavelength of about 750nm. Background technique [0002] Consumers continue to demand products that meet their daily styling and conditioning needs without damaging hair. The perceived and sometimes actual effects of various treatments and tools such as blow drying and flat irons can have deleterious effects on the acute and chronic nature of the hair. [0003] Permanent methods or detanglers generally include the steps of applying a composition to the hair com...
