A cosmetic treatment process for a keratin material, including placing the keratin material in contact with at least one cationic polymer with a molecular weight of between 500 and 5,000,000 daltons, and either simultaneously with or consecutively to the placing the keratin material in contact with said cationic polymer, an electric current is applied using at least one electrode for a time that is sufficient to deposit at the surface of the keratin material an effective amount of said cationic polymer.

A system for treating the hair, to be connected to a water inlet, that includes at least one source of a cosmetic product, a water-dispensing device to convey the water to the hair, an adjustment device making it possible to inject, into the water, the product originating from the at least one source of product and to vary the content of product originating from this source in the water conveyed to the hair by the dispensing device and/or the amount of product conveyed to the hair by the dispensing device, this adjustment being able to assume at least one intermediate value between minimum and maximum content and/or amount values, a pressure booster to increase the pressure of the water at the inlet of the dispensing device beyond the pressure of the water at the inlet of the system.

The present disclosure concerns a cosmetic product for changing the natural colour of keratinous fibres, in particular human hair, which contains at least one package (VP) as well as a cosmetic composition (KM) contained in this package (VP). The package is formed from a multilayer foil (F) which contains at least two polymer layers (P1) and (P2) as well as at least one barrier layer (BS). The cosmetic composition comprises at least one oxidizing agent, at least one C.sub.8-C.sub.30 alcohol, at least one special anionic surfactant as well as at least one non-ionic surfactant. Using the package (VP) in combination with the cosmetic composition (KM) surprisingly does not result in expansion of the package or excess loss of water from the medium (KM) during storage.

The subject of the present invention is a process for dyeing keratinous material, in particular human hair, comprising the following steps: Application of an agent (a) to the keratinous material, the agent (a) containing at least one organic silicon compound and at least one surfactant, and Application of an agent (b) to the keratinous material, the agent (b) containing at least one pigment.

A second object of the present invention is a multi-component packaging unit containing means (a) and (b) in three separately assembled containers.

The subject matter of the present disclosure are agents for oxidative hair lightening or hair coloring, containing from about 70-90% by weight of a total of % of water, alkalizing agent, optionally a colorant, and a certain mixture of a cross-linked copolymer of acrylic acid and non-ethoxylated esters of acrylic acid with linear C10-C30 monoalcohols, anionic surfactant and linear, saturated C8-C22 alkan-1-ol, and sodium polyacrylate, whereby the brightening or coloring agent obtains an application-technically optimal viscosity and the consistency of a gel-like cream with an excellent haptics.

The present invention provides a gas supply device for lightening hair color, including a separating layer and a functional unit wrapped in the separating layer, wherein the functional unit includes a metal peroxide, an activator and a catalyst, the gas supply device further wraps a composition that generates carbon dioxide, nitric oxide, and/or hydrogen. The present invention discloses a use and method of a gas supply device for lightening hair color, including supplying oxygen to the scalp and the hair, and further reacting to generate active oxygen. The present invention further discloses a method for eliminating a dye on the hair by using the gas supply device.

A blending method is described for preparing a blended mixture. The blending method for preparing a blended mixture, the method includes: providing a control system having at least a processor, a computer-readable memory, and a display, wherein the memory contains software configured to receive a formula defining instructions for preparing a blended mixture using one or more blending materials and amounts for producing a batch size of the blended mixture on a scale; monitoring a weight on the scale as blending materials are added to a receptacle on the scale, both individually and in total; indicating on the display the amounts of the blending materials that have been added to the scale, both individually and in total, to prepare an amount of a custom blended mixture based upon the selected blending materials; determining an end weight of the custom blended mixture after a user has used the custom blended mixture; and recalculating a needed amount of the custom blended mixture by subtracting the end weight of the custom blended mixture from the prepared amount of the custom blended mixture.
