The present invention is directed to a hair color applicator. The hair color applicator may comprise an applicator brush and a base. The applicator brush may be operable to apply one or more hair colorings to hair. A trough in the base may hold the one or more hair colorings. One or more removable dividers may be coupled to the trough to separate the one or more hair colorings. The one or more hair colorings may be applied to a brush head of the applicator brush by placing the applicator brush on the base and rotating a plurality of bristles of the brush head through the trough. The one or more hair colorings may be applied to the hair by brushing the hair with the applicator brush.

A surgical cleaning device and method of use having a housing, a drive shaft rotatably mounted, having a rear end and a front end, a brush head positioned at the front end and arranged outside the housing, to which a plurality of elastically deformable bristles are attached, a pump connected with the drive shaft for pumping a rinsing liquid, a gearbox that is connected with the front end of the drive shaft and with a rear end of the tube and which translates the rotational movement of the drive shaft into an oscillating linear movement of the tube and the brush head, wherein the tube is mounted movable in a linear manner; the brush head in the region of the elastically deformable bristles has at least one ejection opening, wherein the tube opens liquid-permeably through the at least one ejection opening in the direction of the elastically deformable bristles.

A paintbrush features an elongated handle with an interior passage and a head with a wider interior cavity. The handle defines an inlet at its first end and an outlet at its second end, which fluidly connects to the head's inlet, forming a continuous fluid flow path to the head's outlet. The head's interior cavity includes a first longitudinal section configured as a temporary fluid retention chamber and a second longitudinal section configured as a sleeve for a plug with drainage holes. The handle may have a tapered external profile and an exterior gripping surface. An endcap may be releasably attached to the handle's first end, which may also be configured for fluid source attachment.

A device comprises an interdental brush, a delivery component, and a lighting system. The interdental brush is disposed at a first end of the device and includes a working part and a connector. The delivery component includes a guide head and a sliding mechanism that is mechanically connected to the guide head. The guide head includes a bended tube within which the working part of the interdental brush is positioned. An outlet of the bended tube is disposed at an end of the guide head. The sliding mechanism includes a sliding block and an interdental brush connecting mechanism that mechanically connects the interdental brush to the sliding block. The lighting system includes a switch and a light source. The light source is disposed at the first end of the device and is electrically coupled to the switch through the guide head that houses the interdental brush.

A hair coloring adapter for a hair coloring device, and methods use. A hair coloring adapter is comprised of an adapter cap detachably coupled to a bristle adapter comprising an adapter base, a plurality of support structures protruding from the adapter base, a plurality of formulation application zones, a plurality of non-application zones, and a plurality of formulation ports. A method of dying alternating hair strands of a subject comprises clipping a hair coloring adapter onto a first segment of hair of a subject; coupling the hair coloring adapter to a hair coloring device; activating the hair coloring device; and drawing the hair coloring adapter along the segment of hair of the subject, thereby brushing hair formulation onto selected hair strands of the subject in alternating patterns based on positions of the formulation application zones and the non-application zones.
