This man had a hair transplant a few weeks before these bald spots appeared on his head. More and more of them appeared. To make the diagnosis, a biopsy needs to be done. It is likely a scarring alopecia, but it could be a variety of scalp/hair diseases triggered by the hair transplant. I have seen men who never had alopecia areata, then get a hair transplant, and alopecia areata appears from days to weeks after the transplant. A surgeon must have a keen eye and perform a good trichoscopic examination on the head of all of his patients before the surgery. As a surgeon, I don’t like surprises, and I am sure that you, as a patient, wouldn’t like them either.
