Transplanted hairs can be moved from one place to another if there is a good reason to do so. From where to where is my basic quesition seconded by why.
Hair follicles (hair transplants) can be moved more than once. For example, I have done this when patients had a Fleming/Mayer flap after transplants that they did not like. Rather than discard the transplants, they are moved elsewhere, but the patient understands that the successful yield will decrease each time the grafts are moved.
