First Methods Used in Hair Transplantation
As a student in the Department of Dermatology in the late 1940s, Dr. Norman Orentreich became interested in helping patients with baldness and bald spots on the scalp. His studies sparked his interest in this field and he conducted several experiments. In one of his research, he realized that hair transplanted to a certain area of the scalp from other areas did not have the characteristics of the hair where it was transplanted. Instead, the newly transplanted hair retained the characteristics of the hair from which it was taken. This finding was the basis Orentreich later used to further his research and develop the concept of “donor sovereignty”.
In 1952, the world’s first modern hair transplant operation was performed on a patient suffering from male pattern baldness. This operation started a process called “Hair Plugging”, which has led to the creation of a billion-dollar industry where millions of operations have been performed to date.
Generally, in these operations, the surgeon uses a round puncture instrument (4 mm wide) to remove tissue filled with hair grafts. These punctured tissues are called “plugs” which are then implanted into the bald areas. Although the results are not acceptable even by today’s hair transplant standards, it was a prominent hair transplant technique for decades.
Due to the transplantation of the entire tissue as a large whole, the transplanted hair is placed in groups, leading to a doll-like hair appearance. With this technique, the hairline is difficult to repair and can leave visible scars in the donor area.
For a typical male patient with Androgenetic Alopecia (AGA), the process can take about 16 weeks with 4 sessions 4 weeks apart. The surgeons’ removal and implantation of large amounts of tissue can cause pain and the repetition of the same procedure every month can be mentally draining for the patient. Fortunately, new and improved techniques were introduced in the early 1990s.
