Hair transplantation is an operation that takes hair from the back of the head and moves it to the area of hair loss. The fringe (back and sides) of hair on a balding scalp is known as donor dominant hair which is the hair that will continue to grow throughout the life of most men. This hair retains its characteristics of growth after it is transplanted to the bald area. Donor dominance (of hair from the back and sides of the head, which continues to grow throughout life) is the scientific basis for the success of hair transplantation. Dr. Okuda of Japan first described the use of transplanted hair to repair scarred eyelashes and eyebrows. Dr. Norman Orentreich published the first widely read report on hair transplantation surgery in 1959 and the field of hair transplant surgery was born.
