Abstract
Devices, systems, materials, and methods for contouring a volume of hair are described. A hair contouring device can include a contouring source. The contouring source can be configured to generate contouring electromagnetic radiation within a first energy range to induce a conformation change of a hydrogel formulation. The hair contouring device can include a fixing source. The fixing source can be configured to generate curing electromagnetic radiation within a second energy range to induce a photo-curing transition of the hydrogel formulation. The hair contouring device can include an input component. The hair contouring device can also include control circuitry, electrically coupled with the contouring source, the fixing source, and the input component. The control circuitry can be configured to receive an input from the input component and to control the contouring source or the fixing source in accordance with the input.
