Liquid-impermeable sheets, suitably composed of aluminum foil, are provided with a coating of pressure-sensitive adhesive, preferably adjacent one edge of the sheet, and optionally, a strippable cover to protect the adhesive prior to use. The process comprises separating a portion of hair to be treated from the remaining hair on the head, adhering one of the liquid-impermeable sheets to the scalp and hair of the head immediately adjacent and below the roots of the portion of hair to be treated, and treating the selected portion of hair with any desired liquid-treating agent such as a bleach or dye and permitting the treated hair to overlie the central portion of the liquid-impermeable sheet while the treating agent takes effect and, optionally, folding or rolling the sheet toward the head and then folding the edges inwardly to form an envelope, thus isolating the treating agent from the remainder of the head of hair and treating only the selected portion of hair.
A liquid-impermeable imperforate sheet adapted to be removably secured to the scalp so that one edge is positioned closely adjacent the roots of selected strands of hair to be colored or bleached, a pressure-sensitive adhesive along only said one edge capable of adhering firmly but releasably to skin and hair and having substantially greater adhesion to said sheet, said sheet being of a thin, flexible metallic material capable of being folded and crimped to form a self supporting compact enclosure for said strands of hair to be treated, said enclosure retaining its folded configuration due to the crimping of said sheet by application of pressure alone.
