Do not bother with meds. If your hairloss is stable you have reached your final Norwood pattern. Meds will only do slight improvement at this stage and not worth it.
Your plan is good but NW1 is ambitious, can only get NW2.
1. FUT is such a dated technique, I hate the ugly scar it leaves. Some people still prefer it but meh. You look good now but when you get old and your skin isn’t so nice, that scar going to be look hideous. Look at Joe Rogan, just hideous.
2. Zarev. Pitella. Eugenix
3. Sure if you’ve a massive beard and don’t mind thinned look behind hairline in some places (midscalp/crown). 12k grafts.
4. Don’t bother and condemn yourself to a life of drugs. You’re too far gone
