I went in for consultation in July 2015 and opted for a 2800-graft FUT strip procedure. I was lucky and got an August appointment when a spot...

FUT 5397 Grafts with Dr. John Diep - Los Gatos, CA

This is a very belated review of my experience of FUT surgery with Dr. Diep. But better late than never, I guess. This is based on notes I took right after the surgery. I was age 56 the day of surgery and roughly Norwood 5.5 to 6 pattern. I did a free in-person consultation with Dr. Diep in December 2014. Fortunately I live only a half hour away from the clinic.
