This specification describes a beard grooming device that provides a comb that may be protected with a cover, or a liquid sprayer in a handle attached to the comb, or both. The device allows a user to comb the beard and/or apply an active agent to the beard or other hair.

A dry-cleaning brush includes a body, a base plate and a bristle component. A storage cavity used for storing shampoo powder is formed between the body and the base plate. A powdering device is arranged in the storage cavity and includes a pressing rod arranged on the base plate, lever assemblies, pistons, and at least one leaking hole formed in the base plate, and the pistons are located at openings of the leaking holes. Each lever assembly includes a lever having two ends respectively clamped on the pressing rod and the corresponding piston. A rebound mechanism is arranged between an elastic gland, the pressing rod and the base plate. The powdering device controls the pistons based on the lever principle, the elastic gland and the pressing rod are pressed to drive the levers to pull the pistons away from the leaking holes.

A device operable to apply coloring dye to hair while coordinating parting of the hair can include a reservoir sized and shaped to receive a coloring compound, a dispenser head in fluid communication with the reservoir, the dispenser head operable to dispense the coloring compound, and a parting comb attachment removably coupled to the reservoir. Related methods of use are also provided.

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.
