@BeHappyI believe that a Norwood 4 or below who is on medication — stabilized — and has adequate donor caliber, and who starts with FUT for their first two to possibly 3 procedures, shouldn’t have to worry about running out of donor. Using myself as an example because I’ve had two FUTs, albeit on the low-end in terms of graft count, but my crown still isn’t where I want it to be.
Could fin stop working for me and then have to worry about accelerated loss of native hair? Sure, but then I’d switch to dut.
