The present invention relates to a novel color-changing foil device. The device is designed to notify stylists when a hair treatment process is complete, preventing hair from being overprocessed and overtreated. The device comprises a color-changing hair foil which is used in the process of hair treatments. The hair foils comprise heat activation elements which produce a color change when a predetermined temperature reaches a specific threshold. Thus, the hair foil changes color when it reaches a certain temperature, thereby indicating that the hair treatment process is finished or needs to be stopped to protect the hair from damage.

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.

A system, method, and device for foiling hair while using a technique similar to balayage. The system uses hair foils with at least one jagged edge, essentially functioning as a stencil for the balayage design technique. As such, the foil may not leave a straight demarcation when color is brushed off the ends of the foil onto the hair underneath from the previous foil layer, allowing the hair artist to employ a foiling process that is a combination of a paneled layering technique and a balayage technique.

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 hair painting board fosters application of coloring and other hair treatments in an efficient manner. The hair painting board has a curved body to conform to the shape a client's scalp. A wider end of the hair painting board provides the option to a hair stylist to select a variety of hair strands from various areas of the scalp and apply treatment thereto quickly and efficiently. A narrower end is useful for application of treatment at smaller areas of the scalp. One or more notches in the curved body aid in grasping and manipulating the hair painting board.

A mobile color and style application device is disclosed. The device includes a base. The device further includes an adjustable tower coupled to the base. The adjustable tower including one or more tower locks configured to adjust a vertical height of the adjustable tower. The device further includes a plate coupled to the adjustable tower. The plate includes one or more tower locks configured to adjust a tilt angle of the plate. The device further includes one or more platforms. The one or more platforms are configured to couple to a portion of the plate via a quick-connect coupling mechanism. The one or more platforms include one or more cut-outs. The one or more cut-outs are configured to conform to a portion of at least one of a neck or a head of a user.

A hair color board includes a divider body having a plurality of elongated peaks alternating with a plurality of elongated valleys. The plurality of elongated peaks and the plurality of elongated valleys extend to an end. The end may be concave such as to be positioned against a person’s head.

A mobile color and style application device is disclosed. The device includes a base. The base includes one or more vertical legs including one or more lockable wheels. The device further includes an adjustable tower coupled to the base. The adjustable tower including one or more tower locks configured to adjust a vertical height of the adjustable tower. The device further includes a plate coupled to the adjustable tower. The plate includes one or more tower locks configured to adjust a tilt angle of the plate. The device further includes one or more platforms. The one or more platforms are configured to couple to a portion of the plate via a quick-connect coupling mechanism. The one or more platforms include one or more cut-outs. The one or more cut-outs are configured to conform to a portion of at least one of a neck or a head of a user.

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 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.
