1. A brush, comprising: a bristle-holding tree having bristles; a housing disposed around the bristle-holding tree, the housing having at least one aperture through which at least one of the bristles extends; a stem base engaged with the bristle-holding tree; and a locking mechanism engaged with the stem base, wherein the locking mechanism includes an upper locking mechanism comprising at least one first groove and a lower locking mechanism comprising at least one second groove, wherein the at least one first groove engages with the at least one second groove when a member engaged with the lower locking mechanism is depressed, and wherein the locking mechanism is structured to move the bristle-holding tree and the stem base as a unit longitudinally relative to the housing between an extended position and a retracted position, wherein: (a) in the extended position, the bristles extend to a protrusion distance relative to the bristle-holding tree through the apertures of the housing, and (b) in the retracted position, the bristles retract to a retraction distance relative to the bristle-holding tree, wherein the bristle protrusion distance is greater than the bristle retraction distance.
