The invention relates to a hair treatment method for treating hair by using a hair treatment tool (1). The hair treatment tool (1) includes: a fiber structure member (5) that retains a hair cosmetic; and a liquid-impermeable sheet (3) to which the fiber structure member (5) is fixed. The fiber structure member (5) retains a hair cosmetic that includes a pigment and a film-forming resin, and is sealed in a packaging (2). The hair treatment method of the invention treats hair by: exposing a surface of the fiber structure member (5) of the hair treatment tool (1); and bringing the fiber structure member (5) into contact with hair, and in this state, moving the fiber structure member (5) in a direction of orientation of the hair.

A hair holder (1) includes a tubular body (2) that is constituted by a sheet and through which a bundle of hair can be inserted from an opening (21) at a one end toward an opening (22) at the other end, and has a flat shape. The tubular body (2) includes a first surface sheet (23A) and a second surface sheet (23B) that are located on the inside and the outside, respectively, in a state in which the hair holder (1) is rolled up. Side regions of the first surface sheet (23A) and side regions of the second surface sheet (23B) are joined to each other, thereby forming a pair of side joined regions (24) in the tubular body (2). The side joined regions (24) have a plurality of second-surface-sheet-side recesses (25) along a longitudinal direction (X) of the side joined regions (24), the recesses being recessed from the second surface sheet (23B) side toward the first surface sheet (23A) side.

Disclosed are precut hair coloring foils and a method of use thereof. The precut foils are thin sheets, particularly of aluminum, are nonrectangular in shape, and may comprise a trapezoidal shape. Fold guides may be included to assist the stylist in folding the foil in different places for varying applications. The unique shape of the foils allows for better coloring of hair resulting in increased time between hair coloring sessions to maintain a desired look.

A hair extensions separator has a plurality of lateral grooves and a wrapping mechanism to wrap the separated hair extensions in the plurality of lateral grooves. A method for separating and wrapping hair bundles can be performed and in one embodiment can be performed using the hair extensions separator. In various embodiments, the hair extensions separator has a comb-like structure used in conjunction with the plurality of lateral grooves to aid in separating the hair. In other embodiments, the hair extensions separator may further comprise adjustable sizes of the plurality of lateral grooves.

A hair coloring device comprises: a first rectangular sheet having a top edge, a bottom edge, opposing side edges, a front surface, and a back surface; a second rectangular sheet having top edge, a bottom edge, opposing side edges, a front surface, and a back surface; wherein the back surface of the second rectangular sheet is secured to the front surface of the first rectangular sheet after hair coloring is applied to hair disposed between the first rectangular sheet and the second rectangular sheet and wherein the top edges, bottom edges, and opposing side edges are aligned; and wherein the first rectangular member and the second rectangular member each comprise a transparent thermoplastic material. A process of coloring hair includes using the hair coloring device.

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.

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.

Processes and kits for permanent waving keratin fibers achieve durable shiny waves. The processes comprise treating fibers with a reducing composition, a non-reducing and non-oxidizing alkaline composition, optionally and acidic composition and finally an oxidizing composition, wherein, after processing the reducing composition, the fibers are rinsed off and the fibers are inserted into a curler having a tubular body with a first opening located at the first end and a second opening located at the second end and, wherein the curler is configured to allow keratin fiber streak to be inserted from the first opening toward the second opening and it is capable of being rolled up.

A dispenser has vertical walls defining an interior volume for receiving a stack of Z-folded sheets of hair treatment foil with a pre-determined size and pre-determined weight, a lifting platform on which the stack of sheets is placed, a dispensing guide across the top of the vertical walls with a dispensing slot; and a lifting device such as one or more springs which provide sufficient lifting force to the platform to maintain the topmost sheet of the stack to be position immediately below the dispensing guide as sheets and weight are removed from the stack.

A method for coloring hair on a human head using a blow dryer is provided. According to the method, the hair is separated into sections of different shape (e.g., rhombic, square, triangular, horseshoe-shaped, etc.). Then, subsections of hair are isolated in each section. Each subsection of hair is grabbed and pulled (in a direction of a cut line of the hair) with one hand of a hairdresser, and different (e.g., short, medium-length, and long) layers of hair are blown out of the subsection of hair by an air flow from the blow dryer held in another hand of the hairdresser. After that, at least one of the blown-out layers of hair is fixed (e.g., with a clamp) and colored. The hair thus colored is then rinsed and treated according to a post-coloring recipe.
