<p>A hairbrush comprises a bristle-retaining surface 530 and a bristle field of at least 100 bristles that are individually deployed to the bristle-retaining surface, the bristle field comprising at least five different bristle heights that differ significantly from each other, the bristle heights varying in a substantially random manner and being substantially independent of location on the bristle-retaining surface, each bristle having a width of at least 0.5 mm, and at least 60% of the bristles having a rounded end. The bristles are preferably deployed at a substantially constant density on the bristle-retaining surface. A hairbrush is also disclosed comprising a distal end surface defined by ends of bristles of a bristle field that is irregularly and substantially randomly shaped. A further disclosed hairbrush has a bristle field comprising at least one height outlier subset having a count that is at least 10% of the total bristle count, the bristles of the subset being scattered at irregular and non-periodic locations within a selected area of the bristle-retaining surface. The hairbrushes are suitable for detangling human or animal hair.</p> |
