I think the I’ve seen the safest amount is between 40/50 grafts but more can be done for better density! One gent on here went to Dr Leal in Brazil & had over 70cm2
in this light, it literally looks fine but in the 5th pic down on your initial post, you can see the density issues. a good doctor could sort out the density for you no problem i assume
are you on any meds?
even if you only shave the recipient and not the whole head you may be able to conceal the recipient area with the remaining hair, that’s what I did anyway
