Shedding After a Hair Transplant

I had a hair transplant 4 months ago and I lost hair in the months that followed. Is that unusual and will it return?

Shedding is not common after surgery on a patient who had a previous hair transplant nor on patients who are taking Propecia. In the days before Propecia was available, hair loss (shedding) following the first hair transplant was common in the younger men and less common in the men over 40. When the hair loss happened in the younger men, it frequently reflected what I might have guessed would have come out by itself in the next year or two. I only remember a small hand full of patients who lost some of their older hair transplants after a new procedure, but all of them (less than 1% risk) had the hair return at between 4-6 months. If it is the transplanted hair from a previous hair transplant, I am confident that it will all return.
