Abstract

Abstract A piece of silk (blocked to head contour) is coated on its convex surface by a liquid neoprene solution to which a small amount of oil-base flesh-colored tint is added. One or two coats are applied and dried to provide a strong, resilient, natural, and waterproof scalp base. The neoprene coating provides a convenient means for making attachments to the scalp base. Hair is applied by any feasible method or by uniquely cementing neoprene tacked wefts of hair over the coated scalp base by application of additional neoprene solution. The coated and wefted scalp base is self-supporting. A coated scalp base having conventionally inserted hair has tape-supporting ribbons and a part-supporting strip secured over it under patches of the coated scalp base material cemented by the aforementioned coating solution. Part-forming hairs are inserted at a shallow angle into a neoprene part-supporting strip to form a permanent apart. A number of short burned hairs extend from the front edge of the scalp base under longer overlying hairs to provide a natural hairline. The scalp base is perforated to pass scalp oxidants through it either by inserted hairs or independent piercing.
