If one’s face (or jaw) is asymmetrical due to bone shape, then yes you’re correct. But if it’s due to the positioning of the jaw (forward/backward, or offset to one side), or even the musculature of the face, then I can see how shifts there could be possible for sure.
Certain people may be more genetically prone to baldness than others, but there are still other things that must be present before hair loss occurs. One of the more popular theories is a buildup of DHT in the scalp which leads to miniaturization and eventual dormancy of hair follicles. Another theory involves scalp inflammation as a cause. In both instances, avoiding or minimizing the circumstances will override a genetic predisposition to hair loss.
Your genetic potential could be a limiting factor, but there are ways to get around that… and I don’t know that it’s truly a limiting factor, more so how much effort is required. Substances like myostatin inhibitors etc tweak the biochemistry to make someone more like another person who is (I hate using this term, as it implies conscious intent, to me at least…) “genetically gifted”.
