Hair transplants don't work too well with fighting.
Fighting = Secret juice = a lot of testosterone
The more testosterone, the more dihydrotestosterone DHT
-> Hair loss again, because hair follicles react to DHT by "falling out" actually thinning till too weak.
That's why doctors prescribe medication or supplements for blocking the conversion of testo to DHT after a transplant.
You'll get some bad side effects over the years or decades though from those.
They often start really little, so you won't notice them, or think it is aging. Till it is often too late.
