A brush includes a brush head moving mechanism and a removable brush head for applying flowable matter to a surface, the brush head including a chamber for retaining flowable matter, a chamber delivery wall with outwardly protruding bristles and with delivery ball ports among the bristles into each of which a matter delivery ball is rotatably seated and retained by ball retaining structures to partly protrude through the delivery wall, and an opposing chamber mounting wall with brush head mounting means for connecting the brush head to the moving mechanism, and having a chamber side wall interconnecting the chamber delivery wall and the chamber mounting wall to form a closed and sealed container for the flowable matter.

A heated shaving brush having a housing with an interior space that houses a shaft that acts as a tube to allow shaving cream or similar lubricating agent to pass through to a bristle assembly that a user applies to their body. The shaft is adjacent to a heating element that is powered by alternating or direct current, thereby heating the shaving cream as it passes through the hollowed shaft. A graduated knob can modulate the speed at which the shaving cream passes through the shaft, thereby increasing or decreasing the temperature of the shaving cream before it is applied to a user's face.

A cosmetic device with an exchangeable application head and a device body is disclosed, wherein the device body contains a motor and drive mechanism, an actuating switch, a power supply, a head recognition element and a control element adapted to control the motor and drive mechanism based on an actuation of the actuation switch and the application head recognized by the head recognition element. It is provided that the head recognition element comprises at least one mechanical switch disposed on a carrier fixed at the device body. Further, a flexible actuation area is disposed in front of the at least one mechanical switch. The exchangeable application head has at least one recognition generating protrusion actuating through the flexible actuation area on one of the at least one mechanical switches when the exchangeable application head is mounted at the device body.

An apparatus for shaving and a kit for shaving. The shaving apparatus comprises an upper bowl and a lower bowl. The upper bowl includes a protruding lip around an upper opening and a flat ledge around a middle circumference. The lower bowl includes a lip around a lower opening. The flat ledge of the middle circumference of the upper bowl rests on the lip of the lower opening of the lower bowl.

A wall-mounted back scrubber apparatus for cleaning one's back in the shower includes a housing having a housing defining a housing inside. The housing front side has a central aperture and a plurality of secondary apertures extending through to the housing inside. A plurality of suction cups is coupled to the housing back side and is configured to selectively engage a shower wall. A motor is coupled to the housing within the housing inside and has a motor shaft extending through the central aperture. A central brush is coupled to the motor shaft and a central gear is coupled to the motor shaft within the housing inside to drive a plurality of secondary gears attached to a plurality of gear shafts coupled to the housing back side and extending through the plurality of secondary apertures. A plurality of secondary brushes is coupled to the plurality of gear shafts.

A back and shoulder cleansing machine for a shower wall is disclosed. The device mounts to the wall using suction cups and is connected to the shower head water supply for dispensing water and soap from the brush body. Additionally, the brush body rotates and also has a pair of elevated brushes extending from the main device. The elevated brushes are also configured to have a swiveling motion and are then used to wash a person's shoulders. Additionally, the main body includes a refillable soup revivor which is accessed from a top end of the main body. Excess water from within the main body is then dispensed from a release valve at the bottom end of the main body.

A disposable neck duster for barbershops is disclosed. A handle unit with a cylindrical shape of multiple cross-sections in order to be held firmly by a user, wherein said handle unit encloses a cylindrical bar disposed vertically from a bottom section to a top section within said unit and is coupled with a push button at said bottom section of said unit. A dusting/head unit detachably coupled to said vertical bar of said handle unit top section. A pair of magnets configured to hold firmly said head unit metallic base when said vertical bar is being received inside said annular section.
