An electrolytic brush assembly including a handle assembly; a shroud extending from the handle assembly, the shroud having an aperture at a distal end thereof; and a brush connecting assembly for releasably connecting a brush to the handle assembly whereby the brush extends through the aperture of the shroud. The handle assembly includes an adjustment sub-assembly for selectively moving the brush connecting assembly and a brush connected thereto relative to the handle assembly and the aperture of the shroud.

A combing device that includes a comb handle, a comb head and a protecting member; an air duct is arranged in the comb handle; the comb head is slidably arranged at an upper end of the comb handle, the comb handle is provided with a first limiting structure for preventing the comb head from sliding out from the comb handle, and the comb head is provided with a plurality of groups of comb teeth; the protecting member is connected with the front end of the comb handle; the protecting member is provided with an air suction port in communication with the air duct, and the protecting member is provided with a channel for allowing the comb teeth to pass through; an elastic member is arranged between the comb handle and the comb head.

A cosmetic tool composed of a lid, an inner casing, a lower casing, and a head. The lid and the lower casing are slidably coupled to the inner casing. The head, attached to the lower casing, may be retracted into the inner casing. Additionally, the inner casing includes a plurality of dimples to secure the lid to the inner casing, through frictional forces. The head may be a brush or a sponge to accommodate to various use scenarios. The cosmetic tool includes a critical height and a critical diameter of 75 mm and 30 mm, respectively, as these dimensions allow the cosmetic tool to be carried seamlessly into various articles of clothing, including pockets and purses.

An adjustable hairbrush assembly includes a housing, a brush plate, and an adjustment mechanism. The housing includes a first panel, a second panel, and a perimeter wall connecting the panels, wherein the first panel has a plurality of orifices. The brush plate is in the housing and includes groups of bristles, each projecting through a corresponding orifice. The adjustment mechanism is positioned within the housing and is operatively connected to the brush plate to move the brush plate toward the first panel to thereby extend the groups of bristles such that the bristles in each group of bristles are permitted to fan out to form a more flexible group of bristles, and away from the first panel to thereby retract the groups of bristles such that the bristles in each group of bristles are compacted together in the orifices to form a less flexible group of bristles.
