ABSTRACT:
A reversible process for attaching permanent extensions to human hair in which strands of supplemental hair are joined with a thermostable adhesive to form a plug of supplemental hair, a coating of thermosetting adhesive is applied over the thermostable adhesive and cured, strands of the person's natural hair are threaded through a section of heat shrinkable tubing, the plug of supplemental hair is inserted into the heat shrinkable tubing, and heat is applied to the heat shrinkable tubing so that the thermosetting adhesive liquifies and joins the plug of supplemental hair and natural hair, and the heat shrinkable tubing shrinks in size to compress and seal the junction. The permanent extension can be removed by reapplication of heat to the heat shrinkable tubing.
