This is a college professor who saw a new man in the mirror with this single hair transplant procedure of 2415 grafts. He has fine hair, which often takes more than one session for a completely full look. He told me that no one ever noticed the transition in his appearance, because the change was so slow.
Approximately 2/3rds of the transplants were placed in the first 6 inches of the hairline, which was moved forward, and some grafts were placed in the frontal part of the crown area.
