A comb (100) includes a spine (4) and, extending from the spine in adjacent, substantially parallel planes, a first outer row of teeth (31), a central row of teeth (33) and a second outer row of teeth (32) opposed to the first outer row of teeth. The teeth (10) of the first and second outer rows of teeth and of the central row of teeth are substantially a same length. Spacing of the teeth of the central row (33) is different from spacing of the teeth of the first and second outer rows (31, 32) with the spacing of the teeth being arranged for the removal of head lice and/or nits and/or head lice eggs and/or fleas from combed hair or fur.
