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.

Abstract: A computer system obtains at least one 3D scan of a body surface; automatically identifies, based on the at least one 3D scan, one or more features (e.g., nose, lips, eyes, eyebrows, cheekbones, or specific portions thereof, or other features) of the body surface; and generates a digital 3D model of the body surface. The digital 3D model includes the identified features of the human body surface. In an embodiment, the step of generating of the digital 3D model is based on the at least one 3D scan and the identified features of the body surface. In an embodiment, the digital 3D model comprises a 3D mesh file. The digital 3D model can be used in various ways. For example, output of a manufacturing process (e.g., a 3D printed item, a cosmetics product, a personal care product) can be based on the digital 3D model.
