Abstract: The present invention relates to a process for bleaching keratin fibers, in particular human keratin fibers such as the hair, comprising a step of applying, to said fibers, an oxidizing composition comprising hydrogen peroxide and a non-peroxygenated ammonium salt with a molar mass of greater than 40 g/mol and a step of irradiating said fibers with UV-visible radiation having a wavelength ranging from 200 to 800 nm and a fluence ranging from 1 to 5000 J/cm2, after application of said oxidizing composition.

Abstract: The invention relates to a foil (14) for a strand (12) of keratinic fibers including a first sheet (20) and a second sheet, the first sheet (20) being connected to the second sheet by an articulation, in particular a hinge, the first sheet (20) being movable relative to the second sheet between a closed configuration for illumination of the strand and an open configuration. The first sheet (20) is substantially at least partially transparent to the UV-visible light, and the second sheet (22) is substantially at least partially opaque to the UV-visible light.

Abstract: This device (110) includes a first branch (14) and a second branch (16). The first branch (14) and the second branch (16) are movable relative to one another between an open position for insertion of a lock (12) and a closed position for illumination of the lock (12) in which they define a cavity (20) for illumination of the lock (12), the cavity (20) opening by a first side slit and by a second side slit. The device (110) includes a first confinement member (80) extending in the first side slit over substantially the entire length of the first side slit and a second confinement member (82) extending in the second side slit over substantially the entire length of the second side slit. Each confinement member (80, 82) optically closes the illumination cavity (20) over its entire length when the device is in the closed position.

Abstract: The present invention relates to a process for bleaching or dyeing keratin fibers, in particular human keratin fibers such as the hair, comprising a step of application, to said fibers, of a composition (A) containing one or more chemical oxidizing agents and a step of irradiation of said fibers by means of UV-visible radiation having a wavelength ranging from 200 to 800 nm and a fluence ranging from 1 to 5000 J/cm2, after application of said composition (A); when the process is a process for dyeing keratin fibers, then one or more oxidation dyes is or are also used.

Abstract: The present invention relates to the cosmetic use of a cold atmospheric plasma for preventing and/or treating aesthetis disorders of the healthy scalp.

Abstract: The present invention provides a method of treating hair, the method comprising the following steps: applying a composition to the hair, the composition comprising one or more active ingredients selected from the following: hair conditioning agents; reducing agents; organic or inorganic bases; hair dyes; abrasive solid particles; and moisturizing agents; and combing the hair using a motor-driven combing device (10) comprising spikes that are driven in an oscillating motion.

Abstract: The present invention relates to a method of treating the scalp, the method comprising the following steps: •applying a composition to the scalp, the composition including at least one active ingredient selected from: •anti-dandruff agents; •anti-seborrheic agents; •soothing or anti-irritant agents; •exfoliating agents; and •anti-hairloss agents; and •moisturizing agents; and •performing a massage of the scalp by means of a motor-driven massage device (10, 20) that includes spikes (21) that are driven by an oscillating movement.
