  • Patent number: 4176669
    Abstract: The method involves coating the periphery of a bald area on a person's head with a silicone adhesive sealant to define a peripheral track. The sealant actually penetrates the pores of the scalp and provides a mechanical coupling. Reinforcing material is in turn embedded after applying layers of the coating within this coating about the marginal edge of the bald spot. The marginal track or coatings are permitted to dry and the hair supporting base material of a hair piece is then stitched to the reinforcing material in the marginal track to thereby secure the hair piece in place.
