Abstract: Means is described for performing a hair coloring treatment, such as tinting or bleaching, on a section of head hair and comprises a sheet of material capable of being folded around a section of hair to be treated. The sheet consists of plastics material and is re-usable in contradistinction to previously used aluminium foil. The sheet is also preferably transparent so that a hair coloring treatment can be monitored. At least one bendable inclusion in mesh, wire or strip form is embedded in or affixed to the sheet material, the bendable inclusion(s) having such bendability and rigidity that, when the sheet of plastics material is folded generally along predetermined fold lines over and about a section of hair to be treated with treatment material in paste or like form applied to the section thereby to form a generally closed pocket, the said inclusion(s) in bent form serve(s) to maintain the configuration of the pocket at least for a time sufficient to perform the coloring treatment.
