Abstract: The present invention relates to a general process for treating keratin substances, preferably keratin fibres, comprising the following steps: c) applying to the keratin substances a composition comprising at least one photo-crosslinkable polymer including at least one photo-dimerizable pendant group and at least one hydrophobic pendant group, and d) irradiating said composition on the keratin substances to crosslink the polymer.

Abstract: The present invention relates to a process for treating the hair, which comprises: a) applying to hair a composition comprising at least one aqueous dispersion of silicone particles and polyurethane particles, then or simultaneously, b) heating the hair to a temperature comprised inclusively between 50° C. and 250° C. using a heating device.

Abstract: The appliance for treating the hair, having two arms to be closed over the hair to be treated, at least one of the arms carrying a refill of hair treatment product, the appliance having an electronic control circuit with an electronic memory, this circuit being designed to detect the closure of the arms and the fitting of the refill, the appliance having a steam generator for outputting steam onto the hair and at least one heated straightening plate, the appliance being designed to increment a variable in the memory during the use of the appliance after the refill has been changed and to pass into a downgraded mode of operation in which the operation of the steam generator and/or of the straightening plate is modified when the variable exceeds a first predefined threshold.

Abstract: The invention relates to a device for treating the hair, comprising a first (5) and a second 86) arm that are able to move relative to one another between a moved-together configuration for treating the hair and a spaced-apart configuration for inserting hair to be treated between said arms, the first arm carrying an applicator member (26) for applying a cosmetic product that is able to come into contact with the hair in the moved-together configuration of the arms, and the second arm having at least one housing (38); a pressing element (21) disposed removably in the housing, the pressing element being configured to press the hair against the applicator member in the moved-together configuration; and a support means (40) on which the pressing member bears in the housing, this support means being configured to allow the pressing element to carry out a rocking movement in the housing.

Abstract: The invention relates to a device for treating the hair, comprising a first and a second arm (5 and 6) that are able to move relative to one another between a moved-together configuration for treating the hair and a spaced-apart configuration for inserting hair to be treated between said arms, the first arm (5) carrying an applicator member (26) for applying a cosmetic product that is able to come into contact with the hair in the moved-together configuration of the arms (5, 6), and the second arm (6) having at least one housing (38); a pressing element (21) disposed in the housing, the pressing element being configured to press the hair against the applicator member in the moved-together configuration; a comb (13) mounted on the pressing element.

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 a process for treating the hair, which comprises: a) the application to the hair of a composition comprising one or more polymers containing a silicone unit bearing alkoxy-(aminomethyl)-silyl functional groups, b) the application to the hair of steam by means of a device that is capable of generating steam, step b) possibly preceding, following or being simultaneous with step a).

Abstract: The present invention relates to a process for bleaching or dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising a step of application, to said fibres, of a composition (A) containing one or more chemical oxidizing agents and a step of irradiation of said fibres 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 fibres, then one or more oxidation dyes is or are also used.

Abstract: A device for treating hair, including two arms configured to move relative to one another between a moved-together configuration for treating the hair and a spaced-apart configuration for inserting hair to be treated between the arms. At least one of the arms includes a seal.

Abstract: The present invention relates to an assembly comprising:—a styling tool (5), in particular a straightening iron, to be moved along a lock of hair to which water and/or a cosmetic composition has been applied, and—a collecting device (7) coupled to the styling tool so as to collect a runoff generated during the movement of the tool over the hair on account of the presence of water and/or said composition on the hair, the collecting device having a reservoir (9) for picking up the runoff.

Abstract: A device for cosmetic treatment of human keratin materials, including: a handpiece that includes an electrical assembly, and an application member that is fixed to the handpiece and defines an application surface, the application surface having an area of between 50 and 200 mm2, or between 70 and 150 mm2, and the handpiece is configured to generate a thermal amplitude of greater than or equal to 5° C. between the keratin materials and the application surface for a duration of at least 5 minutes, or a thermal amplitude of greater than or equal to 20° C. for a duration of at least 5 minutes.

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: A method for the cosmetic treatment of keratinous fibres.
