Abstract: The invention is directed to bristles for a hairbrush, in particular for employment in an appliance for personal use as, for example, a curling iron, a curling brush, a hair dryer or the like, including a bristle base (3) and a bristle head (5). In this arrangement, the bristle base (3) is adapted to be fastened to a bristle supporting structure (7). The bristles (1) include at least two sections (9, 11) with cross-sectional areas of different sizes. A section with an increased cross-sectional area (11) adjoins the bristle base (3) having a reduced cross-sectional area, so that the bristle (1) is provided with a neck portion (17) between the bristle supporting structure (7) and the section with the increased cross-sectional area (11).
