Q: What is the Origin of the Term DUPA? — Z.Z., Darien, CT
A: The terms DPA and DUPA were first described by O’tar Norwood in his seminal 1975 publication: Male Pattern Baldness: Classification and Incidence. ((Norwood OT. Male pattern baldness: classification and incidence. So. Med. J 1975;68:1359-1365. Download))
Dr. O’tar Norwood discusses the origin of follicular transplantation, and the influence that Dr. Bernstein’s research and publications have had on the evolution of the hair transplant procedure. Read a segment of the article:
The evolution of “follicular transplantation” can be attributed to three people. Dr. Robert Bernstein coined the phrase and advanced the concept. Dr. Bob Limmer introduced the use of the binocular microscope, providing the technology, and Dr. David Seager showed by direct hair counts, comparing the growth of grafts cut with and without the microscope, how the hair growth was improved when the follicular unit was kept intact.

I just returned from visiting Dr. Bob Bernstein in New York, and was impressed with his operation and even more impressed with his thoughts, observations, and insights into hair transplant surgery. He applies scientific methods to his work, is academically honest, and has an almost eerie instinctive knowledge of hair transplant surgery. Of course he has Dr. Bill Rassman to work with, but it is still remarkable. Dr. Bernstein is best known for introducing follicular transplantation to hair transplant surgery, an idea Bob Limmer has been pushing for ten years with the use of the binocular microscope, but no one would listen to him. Dr. Limmer, however, never used the term follicular transplantation. Using the microscope, you automatically dissect the follicular units. It can’t be avoided if done properly.
The following is a portion of “An Idea Whose Time Has Come,” an editorial written by O’Tar T. Norwood, MD — founder of the Norwood Classification System for Hair Loss — and published in the May/June 1997 issue of “Hair Transplant Forum International”:
