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 skin diseases that were triggered by the hair transplant. I have seen men who never had alopecia areata, then they get a hair transplant, finding the disease 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 prior to the surgery. I, as a surgeon, don’t like surprises and I am sure that you as a patient wouldn’t like them either.
