An apparatus adapted to provide a hair brushing and combing device that supplies heat to the hair and scalp. The device has a generally flat bristle area with an underlying heating element. The apparatus includes varying length bristles and is heated by an internal element adapted to be powered by a standard power source.

A hair brush comprising: (a) a handle; (b) a brush body having: (i) a first side; (ii) a second side; (iii) a third side; and (iv) a fourth side that are connected together forming a substantially square shape; and (c) bristles located in a row along each of the first side, the second side, the third side, and the fourth side.

A hair and scalp treatment device includes a dispenser connected to a cartridge, wherein the cartridge comprises a formulation; a plurality of tips on the device, wherein the tips have at least one opening to dispense the formulation and at least one LED that emits light in the visible color spectrum, wherein the at least one LED is located at the end of the tips; and a controller configured to individually turn on and off the LEDs from the plurality of tips.

A heated hair brush apparatus. A base plate is disposed at a head portion of a housing and has an upper face and a lower face. A plurality of heating elements each extends from the upper face of the base plate to a terminal end. A heat source is disposed in the compartment for transmitting heat through the heating elements. The heating elements and the base plate define a plurality of bores. A plurality of spacers of a material that has a lower thermal conductivity than the heating elements are each received by one of the bores of the base plate. Each of the spacers taper inwardly along at least a portion of the spacer toward the distal end for wedging the spacer in the bore of the heating element to inhibit movement of the spacer relative to the heating element.

An electronic subassembly for a personal care product with a housing defining a chamber having an open end. A first circuit board having a rigid end is positioned within the chamber and a flexible portion is positioned outside the chamber. A second circuit board is positioned within the chamber. The second circuit board has a connector dimensioned to receive the rigid end of the first circuit board.

A combination of a hairbrush having a brush head with a concave central portion and captive ends, along with a thermal coating that includes a desired amount of at least one of aluminum, silver, and/or diamond dust in the coating, results in a hairbrush that can be raised to approximately 200 F. in a short timeframe. A conventional hairbrush without either the coating or the captive ends was unable to achieve the desired temperature.

Various exemplary attachments for hair care appliances and methods of using attachments for hair care appliances are provided. In general, a hair care appliance in an exemplary embodiment is in the form of a hair dryer that has an air inlet and at least one air outlet, and various internal components that facilitate use and operation of the hair care appliance, such as a fan, motor, and heater. In an exemplary embodiment, the hair care appliance is configured to releasably couple to an attachment so that the hair care appliance and the attachment are in electrical communication. The hair care appliance is configured to automatically identify the attachment releasably coupled to the hair care appliance.

Examples of a hairbrush are presented that comprises a heating plate and a plurality of protruding heating elements. The plurality of heating elements is arranged in a pattern resulting in a plurality of undulating paths such that hair strands pass on top of a face of the heating plate and through the plurality of undulating paths during brushing of the hair. A length of at least two of the heating elements, along at least one of the undulating paths, is larger than a width of the at least some of the heating elements. The hairbrush also includes a plurality of heat insulating spacers extending from the heating plate. At least some of the heat insulating spacers are longer than at least some of the said plurality of heating elements, and a plurality of peripheral heat insulating spacers are disposed around at least a portion of the heating plate.

A hair brush with: a handle; a brush body having: a first side; a second side; a third side; and a fourth side that are connected together forming a substantially square shape; and bristles located in a row along each of the first side, the second side, the third side, and the fourth side.

A hair care appliance and methods for drying and/or styling hair are provided. The hair care appliance includes a handle having an inlet and a body coupled to the handle and having a plurality of outlets. The handle can include a fan assembly and a motor assembly and the applicant can include one or more heater assemblies. In one embodiment, the appliance includes at least one heater assembly extending along the body between the proximal and distal ends. In some aspects, the at least one heater assembly can longitudinally separate a first plurality of bristles from a second plurality of bristles. In other embodiments, a baffle for directing airflow is provided. In other embodiments, the appliance is configured to switch between hair drying and hair heating modes.
