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.

Compositions and processes disclosed herein permanent wave keratin fibers and/or human hair for achieving durable waves. The keratin fibers and/or human hair are treated with a reducing composition, a non-reducing and non-oxidizing composition comprising tris(hydroxymethyl)aminomethane, optionally a non-reducing and non-oxidizing acidic composition. Subsequently, the keratin fibers and/or human hair are treated with an oxidizing composition wherein after processing the reducing composition is rinsed off the keratin fibers and/or human hair.

The present disclosure relates to a method for styling mammalian hair fibers, including providing body, straightening, relaxing, curling, or applying any other desired modification to the shape of the hair. The method comprises applying a hair styling composition comprising at least one thermally-curable acid-based monomer to the hair, allowing the monomers to penetrate within the hair and curing such monomers to internally form a polymer able to overcome the tendency of the hair to revert to its native shape. When curing is performed while the hair is in a desired modified shape, the resulting polymers may maintain the modified shape. Suitable compositions and kits allowing to prepare the same are also disclosed.
