I was just told (from another doctor) that one of his patients who had two hair transplants surgeries totaling 5500 grafts, got a third hair transplant and then lost all of the previous hair transplants. The third hair transplant did not grow. A biopsy was done and the diagnosis of Scarring Alopecia was made which clearly caused the loss of the hair. This is an autoimmune process. Of course, the patient was concerned that the scarring alopecia risk was risk he was told about and the patient was angry. This is the very first time I heard about the appearance of a Scarring Alopecia after a hair transplant. I am not certain that there is a one-to-one- correlation between the last hair transplant and the appearance of the scarring alopecia, although the incidence is highly suggestive of it.
