A system and method for one or more hair dye tools with different shapes to imprint different designs onto a person's hair after being dipped onto hair whereby the hair dye tool may be used for other objects such as paper, posters, appliances, skin, or other surfaces whereby multiple hair dye tools may be used in combination to create more intricate designs and patterns for a person.

The present invention relates to a cosmetic device comprising: a support and a composition, carried by the support, for dyeing or bleaching the hair, said composition having a formulation that varies depending on the position on the support, so as to allow shaded dyeing or bleaching to be produced on the hair by transfer.

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.

A product and process for making a transitorily colored sombre hair extension that creates a natural looking sombre effect. The hair extension comprises a hair bundle consisting of a plurality of hair strands having varied lengths. The hair is colored a first color, the bundle realigned, so that the ends of the hair strands are varied in length at the top portion. Then the top half of the hair bundle is color processed to a second color. Again, the strands are realigned and the varied length hair ends are returned to the tail portion. This results in a sombre colored hair extension with a mid-section of the hair bundle that contains transitorily colored hair with a blend of the first color in the top portion of the hair bundle with the second color in the tail portion of the hair bundle.

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.

A system, computer readable medium and method for selective brightening of hair, the method may include or may be preceded by applying at least one photosensitive material to the hair. The method may also include forming at least one pattern of brightened hair by illuminating the hair by at least one pattern of illumination.

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.

The present invention relates to a hair colouring tool which can be used for creating coloured patterns or designs in the hair in an extremely accurate and efficient way. The pattern or design is achieved by dying and bleaching so that the patterned areas are either darker or lighter than the natural hair colour.

A portable hair printer includes a communication module, a printer module that performs a printing operation, a memory that stores a program for printing an image on a surface of a bundle of hairs, and a processor that executes the program, wherein the program is executed by the processor, receives an image to be dyed on the bundle of hairs from the user terminal through the communication module, and transmits the received image to the printer module to perform an image printing operation for the bundle of hairs, and the portable hair printer further comprises a housing having the communication module, the printer module, the memory, and the processor embedded therein, and the housing includes an upper housing and a lower housing hinged to each other around a hinge, and a sensor module.
