I'm seeing widely varying answers: https://realself.com/question/los-angeles-ca-donor-hair-sitesother-than-head-cn-donor-hair-harvested-frm-hw, answers say 5000-7500, and 8000 for the average caucasian male. Another websites says average 6000. https://realself.com/question/albert-city-ia-grafts-man-fue-donor-area, answers say 6000-8000 and 6000. "Estimating the Number of Lifetime Follicular Units" says Type VI has 5393 (4204-6661) depending on donor hair density. What should I believe?
