L’Oréal Patents Hair Contouring Device

US Patent 12,178,895 B2 (David B. Kosecoff, San Francisco, CA (US); L’Oréal, Paris, France.

A L’Oréal researcher patented a hair contouring device, composed of a contouring source, configured to generate contouring electromagnetic radiation within a first energy grange to induce a conformation change of hydrogel formulation; and a fixing source, configured to create curing electromagnetic radiation within a second energy range to induce a photo-curing transition of the hydrogel formulation.

The device includes an input component; control circuitry, electrically coupled with the contouring source, the fixing source, and the input component. The control circuitry is configured to receive input from the input component and to control the contouring source or the fixing source by the input. The device includes a radiation sensor, electronically coupled with the control circuitry; and one or more non-transitory memory devices, electronically coupled with the control circuitry and storing computer-readable instructions that, when executed by one or more processors of the control circuitry.
