There is described a method for colouring hair, said method comprising treating hair with a composition comprising dihydroxyacetone (DHA), in free form or in salt form; optionally drying the hair; and heating the treated hair, including the applied DHA composition, to a temperature of from about 100° C. to about 250° C.

An apparatus for dye dispensing is disclosed herein. The apparatus includes a controller and a tray. The tray communicates with the controller and is configured with at least one opening. At least one canister is configured with an identifier and a dye. The dye is associated with the identifier. A reader communicates with the controller. A dispenser comprises an actuator communicating with the controller and a lever arm. The lever arm is coupled to the actuator and configured with a projection. The reader, based on the identifier, identifies a selected dye in a selected canister associated with a dye formulation. When the selected canister is aligned with a dispensing area, the dispenser applies a downward force on the selected canister and dispenses the selected dye.

In some embodiments, a formulation delivery device comprising a motor and a formulation dispensing assembly is provided. The formulation dispensing assembly comprises a reciprocating nozzle assembly operated by the motor. The formulation delivery device further comprises circuitry configured to generate signals indicative of application of one or more formulation products dispensed by the formulation dispensing assembly, and circuitry configured to transmit the signals indicative of the application of the formulation products to a usage analysis system. In some embodiments, a computer-implemented method of automatically determining at least one hair characteristic for a subject is provided. A computing system receives signals from a formulation delivery device indicative of application of one or more dispensed formulation products, analyzes the signals to automatically determine the at least one hair characteristic, and stores the at least one hair characteristic in a usage data store.

A system for dispensing hair care, the system including a dispensing device, at least one cartridge containing a hair care material configured to fit inside the dispensing device; and a dispensing container removably attached to the dispensing device wherein the dispensing container is configured to accept a portioned amount of the hair care material from the at least one cartridge.

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 disclosure herein teaches a method for preserving cosmetics, including hair dye, that are prone to oxidation. The method uses an apparatus for automatically sealing and resealing, so as to prevent oxidation immediately and thereafter the cosmetic products are dispensed, or breached, from their manufacturer packaging. In the proposed apparatus, this is done by producing negative pressure inside a chamber while the cosmetic product is inside an unsealed container within the chamber. The vacuum is produced by a pump connected to an on-off valve, which is directly or indirectly actuated under micro-controlled processes. The one-way flow of air from the chamber to the apparatus' exterior produces negative pressure inside the chamber. Packaging can be sealed by outside influence or sealed by the pressure difference between the outside environment and the inside of the packaging upon the rapid repressurizing of the chamber. These processes prevent oxidation or degradation of the cosmetic product therein. Data related to the properties of the sealed cosmetic product or products is captured and stored in the device in transient or permanent memory and aggregated, analyzed and retrieved at will by a user. Communication and interaction between user and machine can occur physically (using a switch and a luminous indicator), or wirelessly with a mobile device. The resulting product, created to unique specifications from the original manufacturer packaging, can now be stored for an extended period of time without significant degradation of the efficacy.

The present disclosure relates to a comb, and more particularly, to a hairbrush capable of conveniently dyeing hair by separating, that is, thinning a part of user's hair from other parts during dyeing. The highlighting comb includes a body formed to be elongated in a longitudinal direction; a plurality of comb teeth disposed in the body and disposed to cross the longitudinal direction of the body; and a plurality of first hook bristles disposed in the body, crossing the longitudinal direction of the body, and disposed on an opposite side of the comb teeth with respect to the body.

A hair applicator for the application of medical liquids, hair dye, hair-care products and/or skin care products for the scalp includes a container defining a volume for storing the liquids, in particular a bottle. The container has a neck, a cap configured to close the container at the neck and having at least one application tip with at least one application nozzle for the application of the liquids. The cap is hollow and comprises a valve configured to close the at least one application nozzle. The valve comprises an inner member that is encompassed by the cap and is rotatably attached to the neck of the container and has a valve member configured to close the application nozzle. The cap is axially movable between a first closed position and a second open position by rotation of the cap.

A hair treatment kit comprises a hair treatment composition selected from the group of semi-permanent oxidative and/or direct dye hair colorant compositions, hair bleaching compositions, highlighting compositions, and combinations thereof, a reservoir for holding the temporary hair treatment composition, and an applicator fluidly connected to the reservoir for selectively applying the hair treatment composition to a targeted area of hair. Methods of applying the hair treatment composition comprise selectively engaging the applicator with a targeted area of hair, leaving the hair treatment composition in the targeted area for a time period, washing the hair treatment composition out of the targeted area, closing the reservoir to preserve remaining hair treatment composition for later use, and reapplying the hair treatment composition to the targeted area.

A wireless charging air compressor includes a housing having a motor operably connected to an air pump, which forces air into a cavity, and an actuator operably connected to the cavity for selectively discharging air through a nozzle secured to the housing. A rechargeable battery is operably connected to the motor for providing power to the motor. A wireless charging receiver mechanism is operably connected to the rechargeable battery. The wireless charging receiver mechanism is configured to recharge the rechargeable battery upon interacting with a wireless charging transmission mechanism. This allow the rechargeable battery to be recharged without the need for a hardwired connection.
