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.

The present invention is a hairstyling tool capable of emitting fragrance and/or lights. As non-limiting embodiments, the hairstyling tool may be a hair pick, a comb, or a brush that includes a first end, a second end, a front side, a rear side, at least one edge or sidewall, a first or handle section, and a second or hairstyling section. In addition, the hairstyling tool further includes some, many, most or all of the following fragrance-related components, lights-related components, or their equivalents: a charging port, a power source, a fragrance activator or initiator, a fragrance pump line, a fragrance source or element, a light source, a nozzle or outlet, an activation member, a power source wire(s), and a power wire(s) for lights.

A formula delivery system can be used in conjunction with hair and scalp treatment appliances to supply a hair treatment formulation to the appliance. In one aspect, the formula delivery system delivers hair coloring formulation to the appliance. Formula delivery systems of the present disclosure generally include at least one fluid container configured to retain a volume of formulation for delivery of the formulation to a hair coloring appliance. In this regard, the formula delivery system may be configured to removably couple to an inlet member of the appliance that allows the appliance to draw the formulation from the fluid container for use within the appliance.

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.

Embodiments of hair care apparatus and methods are provided generally comprising a location to provision hair care product, an applicator and a manipulator configured to enable concurrent product application and hair manipulation, and may comprise a product heater, configured to heat product provisioned therein, or be configured for use with an external heating source such as a microwave oven, and provide application of heated product at temperatures both safe for hair health and enhanced absorption. Apparatus may comprise a source of pressure, such as a pump or piston, to generate hair product flow through an applicator, and may be configured to receive product in user fillable or prepackaged product cartridges usable in the apparatus, a product chamber within the apparatus or a removable product reservoir useable in the apparatus. An apparatus may further be configured to support a plurality of manipulators, active applicators and passive applicators.

An improved conditioning comb that allows a user to distribute conditioner or other desired hair care liquid uniformly throughout their hair is disclosed. The conditioning comb is made of parts including a wide tooth and hard plastic comb attachment. The conditioning comb further consists of a detachable holding section that can be refilled with either a cartridge or other kind of liquids as desired by the user. In a preferred embodiment, the conditioning comb consists of a trigger pull or button to distribute the liquid through holes defined by the wide tooth comb.

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.
