Diffuse Un-patterned Alopecia (DUPA) in men is poorly understood by the general public. It is a variant of hereditary hair loss in men. Some say that it is a variant of hereditary hair loss in women, but that is much less understood in the medical literature.


DUPA is a much less common form of hair loss in men. Men with DUPA develop hair thinning all over the head not just the front and top but the back and sides as well. Many of the hairs on the scalp are undergo miniaturization that is similar in MPB (male pattern balding). Hair transplant is not an option for men with DUPA.

Approximately, 3% of the male patients Dr. Goertz sees for hair restoration have DUPA. This is a sub-type of androgenetic alopecia. Incorrect diagnosis of DUPA in men is unfortunate as it may lead to improper treatment. A scalp examination by a qualified dermatologist or full-time hair restoration surgeon is required to rule out other scalp pathology that may mimic DUPA. If the diagnosis is unclear a scalp biopsy may be needed. Understanding male balding patterns for the individual with hair loss will help to determine the right path to diagnose and appropriate treatment of the hair loss.



Medical treatments for men with Diffuse Un-patterned Alopecia include:

  1. 5% Minoxidil (Rogaine)
  2. Finasteride
  3. Low level laser
