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.

Formulation delivery systems, formulation delivery devices, and formulation cartridges for the same are provided. Formulation delivery systems include a reusable handle, a formulation dispensing assembly, and a controller. The formulation dispensing assembly includes a reciprocating nozzle assembly and a pump. The reciprocating nozzle assembly is fluidically coupleable to the formulation cartridge or the cleaning cartridge received within the reusable handle. Formulation delivery devices include a reusable handle configured to receive a formulation cartridge therein, and a formulation dispensing assembly disposed in the reusable handle. The formulation dispensing assembly includes fluid conduits, a pump fluidically connected to the fluid conduits, a reciprocating nozzle assembly, and a controller. Formulation cartridges include a reusable cartridge body, a valve frame, and a disposable refill packet reversibly-coupleable to the reusable cartridge body. The disposable refill packet includes a formulation packet and a body portion configured for insertion into the reusable cartridge body.

One pouch for storage of multiple components of a mixture is described with a first compartment and a second compartment. At least one channel is defined between the first compartment and the second compartment and at least one seal is installed within the channel. An agitator is installed in the first compartment. The seal is breakable and the agitator is removable. Another pouch separates two pockets with an air compartment. The air compartment is breakable.

The applicator for applying a haircare product comprises a base 12 and spikes 14 protruding with respect to the base. At least a plurality of spikes 14 each have a cross section of elongate shape in at least one direction of extension. At least some of the spikes of said plurality of spikes are made at least partially of porous material that is able to absorb said haircare product.

To provide a hair applicator which can fix an applying part to combing elements with a sufficient fixing strength to prevent the applying part from being displaced even by an impact from a fall and also can dispense a sufficient coating amount. The hair applicator is configured such that the coating amount by the applying part is 0.090 g/m or greater (porosity is 80% or higher) and the hardness (ISO7619A) of the applying part is less than A70.

An application device for applying hair-coloring composition, comprising a device body, comprising a first reservoir comprising a first piston; the first reservoir configured to receive a first part of a hair-coloring composition; a second reservoir comprising a second piston; the second reservoir configured to receive a second part of a hair-coloring composition; and a dispensing mechanism associated with the first piston and with the second piston; the dispensing mechanism configured to sealingly move the first piston inside the first reservoir and the second piston inside the second reservoir; and an application cap, comprising a mixing mechanism; and a plurality of projecting tines; wherein the application cap is configured for reversible-connection with the device body such that, when the application cap is connected with the device body, the first reservoir and the second reservoir are sealed from the outside except channels of the plurality of projecting tines which are in fluid communication with the first reservoir and the second reservoir, through the mixing mechanism; and wherein the dispensing mechanism is configured, when activated, to move the first piston and the second piston towards the plurality of projecting tines thereby mixing the first part of the hair-coloring composition with the second part of the hair-coloring composition to form a mixed hair-coloring composition to be dispensed through the plurality of projecting tines.

A composition dispensing device engages a body surface, such as the scalp, while simultaneously dispensing a composition from an attached container on the surface. The device detachably joins a container of a composition and enable uniform dispensing and application of the composition on a body surface. The device comprises a housing that detachably joins with a container of composition. A platform having a plurality of apertures rests coplanar with the housing. A plurality of conduits, or hollow bristles, extend from the platform. The conduits include channels that are in communication with the housing and the container of composition. The conduits are arranged as inner and outer conduits, with the outer conduits being slightly longer to create a generally concave effect. The conduits terminate at an angled tip portion that engages the body surface, while simultaneously dispensing the composition from terminal openings or lateral openings formed at the tip.

A motorized misting hair dye applicator for dispersing a dye mist throughout the hair of a user employs a comb body having a plurality of teeth which each include an ultrasonic atomizer nozzle integral therewith. The comb body additionally includes a dye distribution system which allows stored liquid dye to be directed from a reservoir to each of the nozzles where the dye can be atomized into a mist. A momentary actuating button provides a manual switching interface which allows a user to selectively operate the dye distribution system so as to control the dispersal of dye mist from the nozzles. When a user combines this misting activity with the simple act of combing the teeth through their hair, the dye mist is dispersed throughout the portion of their hair being combed.

The applicator for applying a hair product comprises a base (12) and first group of fixed spikes (14) protruding relative to the base. The applicator further comprises a second group of spikes (16) separate from the spikes (14) of the first group and translatably movable relative to the base between at least one extended position protruding relative to said base on the side of the spikes (14) of the first group, and a retracted position.
