Repair to 40 year old gentleman with a previously done FUT in 2010

This is a 40 year old gentleman with a previously done FUT in 2010 that unfortunately hasn't been successful. His scar has been slightly wide and sensitive and he refused undergoing further FUT as he had an unpleasant experience with post operative recovery/pain. He has a Family Hx of NW 6/7. He himself is a NW6 with a low dipping crown and a limited donor area total surface area. His hair calibre is average. The patient has been using toupees for the last 9 years as his original growth was unpleasant and too obvious. His post operative photos show his shaved pattern but you can clearly see the obvious grafts with the low density and obvious appearance. We had no set number in mind, but we managed to extract 3200 FUE grafts to reconstruct the frontal and Midscalp areas in July 2019. No crown work was done as patient felt that should he have any future work done, he will rather wait for the initial result/ density. The patient is currently satisfied and is planning another density session and possibly some limited crown work in the same setting. I believe we can harvest another 2000-2500 grafts. Would be ideal if he would allow for another FUT/combination procedure. 
Total grafts: 3200
464 single hair refined grafts in Hairline. 
Average hairs/follicle: 2.04
