Abstract: A hairbrush has a shank and a plurality of annular members or rings detachably disposed on the shank. Each annular member has a plurality of unitary, semi-rigid bristles extending radially from the whole circumference of the member. Means are provided for securing the annular members against rotation. These means permit the mounting of the members in forward or reverse manner. The bristles on an annular member mounted in a forward manner are angularly displaced with respect to bristles on an annular member mounted in a reverse manner. The bristles of annular elements mounted in like manner (all forward or all reverse) align to form a number of rows of bristles. When annular elements are mounted in alternating unlike manner, the bristles align to form twice the number of rows of bristles as when the elements are mounted in like manner.
