ABSTRACT:
The use of a sheet made of a polymer material, preferably polystyrene, having semi-flexible, thermally-insulating, hair-clinging, non porous, non slipping properties, as a dye-applying pad for hair highlighting. The polystyrene sheet defines one and another opposite flat portions merging about a fold line. A lock of hair is laid over one flat half portion of the sheet, and a fluid (e.g. gel, cream, or cream gel) dye solution including oxidizing means is applied to the lock of hair. The other flat half portion of the sheet then folded over and flatly compressed against the first portion of sheet to take the locks in sandwich for a sufficient development time to enable permanent hair coloring.
