A formula delivery appliance generally includes a formula delivery head having features to mix, direct, and distribute formulation through nozzles to a desired location, such as the hair or scalp of a user. In this regard, the formula delivery head may include a plurality of nozzles configured to discharge the formulation at a desired flow rate. In some instances, the flow rate across the plurality of nozzles is controlled such that each nozzle has a flow rate within a specified percentage of the average flow rate across the plurality of nozzles.

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.

A drive shaft coupling is provided, such as a coupling used with a formula delivery appliance. The drive shaft coupling generally includes a drive gear and a driven gear, with one of the drive gear and driven gear having a biasing member to allow axial translation. The drive shaft coupling is generally configured to transfer rotation from the drive gear to the driven gear. In one aspect, the drive shaft coupling is capable of alignment and coupling of the drive gear and driven gear upon the radial sliding of the coupling from a non-engagement position to an engagement position.

A method for reducing skin staining during the coloring of hair includes the following steps in the indicated sequence: A1) applying a coloring agent (F) to the hair, A2) allowing the coloring agent (F) to act for a time period from 30 seconds to 45 minutes, B1) applying an undiluted cleaning agent (R) to skin areas that can come into contact with the coloring agent (F) when the latter is washed out, C1) jointly washing out the coloring agent (F) and cleaning agent (R), wherein the coloring agent (F) includes at least one oxidation dye precursor and/or at least one direct dye and the cleaning agent (R) includes at least one anionic surfactant. A multicomponent packaging unit includes the coloring agent (F) and the cleaning agent (R).

A tail comb is disclosed for dispensing a hair product to the roots of a person's hair comprising a comb body, an elongated comb handle outwardly extended from the comb body, a plurality of comb teeth aligned in an array attached at their proximal end to the comb body, extending from and parallel to a longitudinal midline of the body-handle, and an applicator attached to the comb body, wherein the applicator dispenses a hair product to the roots of a person's hair including the person's hair follicles and scalp.

An automatic hair powder dispenser includes a housing, a cartridge that is installed in the housing and accommodates hair powder, a blower fan unit that is installed in the housing so as to be in communication with the cartridge, and a battery that is installed in the housing and supplies electric power to the blower fan unit. Two or more flow tubes through which air supplied from the blower fan unit flows in different directions are provided in the cartridge, thereby efficiently dispersing the hair powder in the cartridge and easily and uniformly discharging the hair powder.

Embodiments provide an ultrasound treatment system. In some embodiments, the system includes a removable transducer module having an ultrasound transducer. In some embodiments, the system can include a hand wand and a control module that is coupled to the hand wand and has a graphical user interface for controlling the removable transducer module, and an interface coupling the hand wand to the control module. The interface may provide power to the hand wand or may transfer a signal from the hand wand to the control module. In some embodiments, the treatment system may be used in cosmetic procedures on at least a portion of a face, head, neck, and/or other part of a patient.

This invention provides a beauty treatment method for the scalp and hair and formula and product for the same. The formula is a water-containing cosmetic composition. The beauty treatment method of this invention utilizes an ultrasonic atomizer to atomize the water-containing cosmetic composition into fine mist droplets ranging from 10 nanometers to 100 micrometers in diameters. The atomized water-containing cosmetic composition is then sprayed onto the scalp in the direction against hair stream and massaged into the scalp against the direction of hair stream. The product of this invention is an ultrasonic atomizer filled with the water-containing cosmetic formulation.

A hair coloring appliance includes a handle and a hair color delivery system supported within the handle. A nozzle assembly is adapted to receive hair color. The nozzle assembly includes a stationary frame and a nozzle array through which the hair color is delivered to the hair and a plurality of filaments adjacent the nozzles which are longer than the nozzles, acting as a stand-off between the nozzles and the scalp. A motor reciprocates the nozzle array back and forth as hair color moves through the nozzles.

The embodiments of the present invention relate to a spray head and a body cleaning device, the spray head comprising: a spray head body comprising a panel provided with spray holes, the panel being provided with a plurality of brush rods, each of which forming a spheroid at an end portion thereof that faces away from the spray head body. The spheroid is made of an elastic material. The spray head, during its use, can penetrate through hair to thoroughly clean the scalp and the bottom portion of the hair near the scalp.
