The purpose of the present invention is to provide a hair treatment method that permits a suitable amount of a component having a hair treatment effect to be deposited uniformly on the hair, and that has exceptional persistence of effects in which hydrophobicity, combability, and smoothness is restored by appropriate heat treatment to hair that has been damaged and in which these effects can be maintained for an extended period of time. The present invention pertains to a hair treatment method characterized by including: (1) a step for applying, to hair, a hair treatment agent containing a copolymer that includes a polysiloxane structure and a polyoxyalkylene structure in the main chain, the copolymer having a side chain that has a trialkoxysilane group or a silanol group; (2) a step for subjecting the hair to heat treatment at 40-230° C.; and (3) a step for rinsing the hair.

A device for head and hair washing of a user carried out by a care operator, where the operator being the same user or not, comprising: a lower bath; a cover, water feeding means, comprising at least a pipe connectable to a water source; water delivering means; water delivering adjusting means, positioned inside the volume created by the cover overlapping the lower bath, and configured so that water delivering adjusting is allowed; water discharge means, associated to the lower bath, comprising a discharge pipe connected to a hole positioned in the lower portion of said bath; the cover has three openings, two of them are arranged on opposite portions to the frontal opening and are provided in the frontal portion of the cover and the third openings is positioned in the rear or upper portion of the opening.

A process for treating, especially is for washing, the hair, including applying at least one cosmetic active ingredient to the head of hair using, a dispensing device. The dispensing device including a hand piece preferably having at least two nozzles, the jets of which collide with one another, to form a mixture of water and of the active ingredient, this mixture originating from a collection basin arranged below the user's head.

The present invention relates to a process for coloring keratin fibers, preferably hair, comprising the steps of: (i) applying onto the keratin fibers a composition comprising (a) at least one compound chosen from alkylaminosulfonic acids and those of the formula (I) and (II), (b) at least one direct dye, and (c) at least one alkaline agent; (ii) heating the keratin fibers; and (iii) optionally rinsing and/or drying the keratin fibers. The present invention can provide superior coloring efficiency, such as color intensity and color lastingness.

The present invention relates to an applicator (10) of cosmetic product (P) for keratinous substances, particularly keratinous fibres, notably the eyelashes, the eyebrows, and/or the capillary fibres, comprising: —a core (40) that extends along a longitudinal axis (X), —at least one block (46) of porous material (47), —projecting elements (48) extending from the core (40) and at least partially passing through the porous material (47).

A system for washing the hair, including a first reservoir for receiving a first liquid (L1) constituted by or comprising water, a second reservoir for receiving a second liquid (L2) including a treatment product diluted in water in an amount of less than or equal to 2.5% by weight relative to the total weight of the second liquid (L2), a shower head with a supply rate of between 0.3 and 5 L/min, configured to deliver a jet of droplets onto the hair. The shower head is further supplied with liquid, taken exclusively from one or other of the reservoirs, with an overpressure.

A method of treating hair to reduce frizz involving the following steps: (i) prewashing the hair with water, (ii) applying a frizz reducing product to the hair using at least one of a brush and a spray, (iii) drying the hair in air, (iv) rinsing the hair with water, (v) drying the hair, (vi) applying to the hair a flat iron, and (vii) rinsing the hair with water. The frizz reducing agent used to treat hair is glyoxylic acid. The specific temperature the flat iron is set will depend on the specific hair type and degree of frizz.
