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.

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.

The invention is directed to a hairstyling comb with fluid reservoir. The comb provides a small internal fluid reservoir, sealed by an endcap, for uniform application of fluid through small apertures between the teeth of the comb. A large aperture is also provided next to the handle, and a cleaning brush is further provided, allowing the user to easily rinse out the reservoir, dry the reservoir with an air hose, and thus prepare the comb for use with a different styling fluid. When the comb is not in use, the cleaning brush may be easily stored within the reservoir.

A conditioning and styling reactivated hair device is an apparatus which can be used to spray formulations to condition, style, reactivate, and/or refresh hair, stimulate the scalp, and help detangle hair. The apparatus includes a handheld grip, a detachable panel, a nebulizing mechanism, a vibration mechanism, and a control system. The handheld grip serves as the base for the apparatus which can be ergonomically held by one hand. Further, the handheld grip includes a palm-bearing surface and an interfacing surface. The detachable panel covers the internal structure of the handheld grip and supports external hair styling aids. The detachable panel further comprises a back plate and a flow guide. The nebulizing mechanism dispenses spray formulations stored within the handheld grip. The vibration mechanism generates physical vibrations for stimulating purposes as well as to aid in dispensing spray formulations. The control system enables the semi-automatic operation of the apparatus by users.

A valve system comprises: a valve body; a valve cap; and a valve plug between the valve body and valve cap is compressed radially and axially, and a central bore extends wholly through the valve body and valve cap and partially through the valve plug. The valve system is welded to a packet which can contain a hair color formula. One or more of the packets are then used in a cartridge compatible with a dispensing device.

A liquid dispensing hairbrush that includes a body having a bristle frame and a base which define a chamber between them. A plurality of bristles extends outwardly from a face of the bristle frame. A spraying member that includes a liquid reservoir, a pump, and a nozzle is retained within the chamber. The nozzle is positioned adjacent a support within the chamber. A trigger provided on the body is operatively engaged with the liquid reservoir of the sprayer. When the trigger is depressed a trigger arm pivots and pushes the liquid reservoir through a region of the chamber, actuating the pump as the nozzle is forced against the support. Liquid from within the liquid reservoir is pumped through the nozzle and sprays through one or more holes in the bristle frame's face and between the bristles. The sprayed liquid is applied to the user's hair as they use the hairbrush.

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.
