US 5,427,120 A · Modular hair treatment brush having multi-sided rotatable modules

Abstract

A modular brush for applying hair treatment solution in a quasi-random pattern includes a brush body and a plurality of removable rotating bristle modules. The bristle modules have tightly packed bristles that retain different volumes of hair treatment solution, such as dye, after the bristles have been dipped into a supply of the solution. The modules may be arranged to achieve the user-selected pattern of treatment. Movement of the brush causes the bristle modules to rotate, providing a fresh supply of solution to the sections of hair which are contacted by bristles and leaving the sections in their natural color where the sections are between bristle modules or between arrays of bristles on the same module. A locking member can be employed to selectively prevent rotation of the bristle modules. A detent-and-notch arrangement may be used to ensure synchronous rotation of the bristle modules.
