    Abstract: Process for making up an area of human keratin materials using a makeup device including a substrate having at least one transfer surface, and a coat of cosmetic colouring ink borne by the transfer surface and obtained by printing, using at least one digital printer, and a cosmetic coating comprising an oil borne by the transfer surface. The cosmetic coating is at least partially superposed on the coat of ink and laying above and/or below the coat of ink, and the process includes the step of simultaneously transferring onto the area to be made up all or part of the coat of ink and all or part of the coating superposed thereon.

    Abstract: Oxidation dyeing process using a substrate bearing at least one oxidation dye, several preservatives and an oxidizing aqueous composition The present invention relates to a process for the oxidation dyeing of keratin fibres, in particular human keratin fibres such as the hair, comprising a step of application, to said keratin fibres, i) of a substrate comprising on its surface one or more oxidation dyes, one or more thiolated reducing agents and one or more organic reducing agents of reductone type, and a step of application, to said keratin fibres, ii) of an oxidizing aqueous composition comprising one or more oxidizing agents. The present invention also relates to a process for preparing said substrate. The invention also relates to an element in sheet form, pretreated by a composition comprising one or more oxidation dyes, one or more thiolated reducing agents, and one or more organic reducing agents of reductone type.

    Abstract: A system for dispensing at least one makeup product, including a cup and a dispenser for filling the cup from the bottom with at least one product, the cup being secured to the dispenser at least while it is being filled with said product. The method for dispensing and evaluating makeup, including the steps of: allowing a video link to be established, for example over the Internet, from a camera at a first site to a second site, allowing the second site to operate either directly or indirectly a dispenser of such a dispensing system, present at the first site, this dispenser making it possible to vary the colour of mixture dispensed, and allowing a person present at the first site to apply the mixture dispensed and to send to the second site a corresponding image, so as to receive in return information relating to the result of the makeup.

    Abstract: The present invention relates to a process for the oxidation dyeing of keratin fibers implementing: a) a step of pretreating said fibers by application to said fibers of a cosmetic composition (B) comprising: i) at least one fatty substance in an amount of greater than or equal to 10% by weight relative to the total weight of the composition (B); and ii) at least one metal catalyst; b) optionally a washing, rinsing, drying and/or rubbing-dry step; c) followed by a step of dyeing by application to said fibers of a cosmetic composition (A) comprising: i) at least one oxidation base, preferably chosen from para-phenylenediamines, bis(phenyl)alkylenediamines, para-aminophenols, ortho-aminophenols, heterocyclic bases preferably comprising at least two nitrogen atoms, and addition salts thereof; ii) optionally at least one coupler; and iii) at least one chemical oxidizing agent. The dyeing process makes it possible to significantly improve the dyeing properties of the coloration, in particular in terms of selectivity, of chromaticity, and of color intensity and uptake. The use of a composition which is rich in fatty substances, i.e. greater than 10%, and contains at least one catalyst pretreatment, before oxidation dyeing, allows a clear improvement in the dyeing properties, in particular in terms of dye uptake onto keratin fibers, of strength and of chromaticity and of selectivity of the color.
