Abstract

A method of implanting artificial hairs in human tissue is disclosed. An artificial hair has a root at one end which is set under the epidermis with a needle means. The needle means has its point shaped for holding an artificial hair at the neck of the root. The root is thrust into an upper region of the hypodermal layer with the needle means. Withdrawing the needle means leaves the root in position, with its tip end turned back, thus permitting the hair to be firmly implanted.
