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 hairstyling apparatus is described which includes a barrel that acts as a hairstyling surface and a central longitudinal axis. The barrel has a first proximal end and a second distal end. A heating element is in thermal communication with the barrel. A rotating member located at the proximal end of the barrel and configured to rotate around the central axis of the barrel, the rotating member including at least one tab extending along a longitudinal length of the hairstyling surface over at least a portion of a longitudinally extending portion of the hairstyling surface. Further, at least one hairstyling element received in said at least one tab.

The present invention refers to a cutting comb (100) for cutting split ends of hair, comprising: a first comb body (1) with at least two first teeth (10), a second comb body (2) with at least two second teeth (20), and cutting means (3) for cutting split ends of hair. The first comb body (1) and the second comb body (2) are arranged to be movable relative to each other in a direction parallel to a longitudinal axis (200) of the cutting comb (100). Furthermore, at least one first tooth (10) of the first comb body (1) comprises at least one first hair-dividing element (11) for dividing hair into hair strands, the at least one first hair-dividing element (11) being immovably fixed to the at least one first tooth (10) and/or the at least one second tooth (20) of the second comb body (2) comprises at least one second hair-dividing element (21) for dividing hair into hair strands, the at least one second hair-dividing element (21) immovably being fixed to the at least second tooth (20).

Systems, devices, and methods for in situ diagnostic assessment and formula dispensing are described. A diagnostic formula applicator can include a fluid dispensing assembly coupled with a comb having a plurality of tines. A tine of the plurality of tines can be configured to dispense a fluid formula to a region of a biological surface via at least one fluid conduit. The diagnostic formula applicator can include hair diagnostic circuitry operably coupled to the fluid dispensing assembly. The diagnostic circuitry can be configured to actuate the fluid dispensing assembly to deliver the fluid formula via the at least one fluid conduit, responsive to determining a user-specific hair cosmetic aspect from hair and scalp sensor information.

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.

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.

A styling device for hair, comprising protrusions, wherein the protrusions comprise a blend of a high molecular weight polyethylene oxide and a water insoluble polymer.

A pet or human battery operated grooming apparatus having a housing, a number of tines formed in the housing, each tine having a slot, and a number of disk shaped blades mounted to a shaft, the shaft mounted in the housing and the blades disposed in the tine slots. A protective cover encloses most of each blade leaving only a slit open to the blade. The tines direct knots or tangles in the hair or fur of the pet, or hair of a human, to the slits and the blades. The user may then rotate the blades to cut the knots. This process occurs without any undue pulling of the associated skin of the animal or human.

A lice removal device (10) comprising a main housing (12) including a first aperture (15) at a first end (14) thereof and a second aperture (17) at a second end (16) thereof. A fan unit (18) is provided within the main housing (12) to draw air in through the first aperture (15) and expel air outwardly through the second aperture (17) A comb unit (43) is securable to the first end of the main housing (12), the comb unit (34) comprising a comb housing (36) and a blade unit (38). The blade unit (38) includes a first side member (46) having a plurality of teeth (44) extending outwardly therefrom and a second side member (48) located adjacent and parallel to the first side member (46) to define an elongate opening (50) such that air is drawn across a first side of the teeth (44) and into the elongate opening (50).

The invention discloses a stirring-extrusion type hair dyeing comb includes a hair dyeing comb enclosure. The hair dyeing comb enclosure is disposed with an inlet cover and a comb head, and a stirring mechanism is disposed in the hair dyeing comb enclosure. The stirring mechanism includes a cylindrical body, stirring shafts and a driving motor; the stirring shafts are disposed in the cylindrical body, the driving motor is coupled to the stirring shafts and for driving the stirring shafts to move along an inner wall of the cylindrical body. The cylindrical body is formed with an inlet and an outlet, the inlet cover is covered on the inlet, the outlet is located at a lower side of the cylindrical body and communicated with the comb head, and an end of the outlet near the inner wall of the cylindrical body is disposed with a resilient normally open switch.
