Adhesive body hair, also known as fake arm hair, is prosthetic hair designed to give the appearance of natural body hair. Fake arm hair is often used in the film and television industry to create realistic costumes for characters with hairy arms.
Fake arm hair can also be used for medical purposes, such as covering up scars or birthmarks. In some cases, fake arm hair can also be used to help people with hair loss regain a sense of normalcy.
