An elongate hair masking sheet (10) of plastics film material for masking first portions of strands of hair of a head of hair from second portions of the strands while the second portions are subjected to chemical action comprises a slit (12) the longitudinal axis of which extends transversely of a longitudinal axis (11) of the sheet (10) and a profile (15) extending adjacent and parallel to the slit (12), the profile providing formations (13, 14) beyond opposite ends of the slit (12) to prevent the slit (12) propagating when the sheet (10) is subject to opposite forces (A,B) along the longitudinal axis (11) thereof. <IMAGE> |
