Have you performed multiple Hair Transplants on one person only to discover that the person might somehow not be suitable for further Hair Transplants because the grafts didn’t grow in from either operation.
No. I have seen men that lost hair following transplants (shock loss), but it was likely their native hair that fell out. This is a real problem in young men, especially if they did not take Propecia before surgery.
I have also seen men with DUPA (diffuse unpatterned alopecia) who have had failed transplants as well. Patients with DUPA are not candidates for hair transplant surgery. Hair transplant failures are most often the result of poor techniques and quality control of the process by the doctor and his staff.
