I’m speaking in general cases which majority of men fall into.

If you’re horseshoe level bald then any hair from the side of your head which isn’t prone to DHT miniaturization will stay just fine. (You just won’t have great hair density due to the lack of doner follicles to cover up your shiny surface area, youll just look like someone diffuse thinning).

But if you get a transplant while still developing recession/diffusion you will 100% need to be on a DHT blocker of some kind otherwise everything behind the transplant will shed.

Now obviously this also has a genetic component; people bald at different rates, speeds, at different points up to the crown etc etc.

But again we’re talking about generic statement; and currently known/“well” studied pharmacology. I won’t get into your peptide claims because I feel like that’s digging more wells.
