elevated cortisol of the mother during pregnancy is reflected in neonates hair
elevated cortisol of the mother also delays their milk production, so probably lowers their prolactin
Would be interesting to see if mothers with psychological problems during the pregnancy get balder kids
i‘d have to agree with you on that, although it’s unclear and probably case dependent how hormones, skull expansion, tension and metabolism/blood flow are interdependent. I think a bad hormonal profile leads to male pattern baldness by itself, but could also expands your skull for example, which restricts blood flow combined with lower metabolism after your teens, which induces hypoxia, which affects test metabolism in that hormones are less likely to be oxidized into hair friendly hormones and more likely to be 5ar degraded. So it’s not „less bloodflow less nutrients“, it’s less bloodflow altered local hormones.
I think a strong metabolism protects against scalp tension/ bloodflow problems and can overcome scalp expansion to a certain degree. A strong teenage like metabolism can also be „faked“ with I think two drugs: minoxidil (which also works in other ways) and caffeine. Basically things that make your heart beat stronger which gets blood in your scalp. This should delay local hypoxia and fibrosis.
Caffeine I think has to be megadosed to achieve that though, upwards of 800mg/ day, and won’t regrow hair or adress more holistic hormonal characteristics that would cause male pattern baldness. I have no idea if bloodflow/ scalp expansion/tension/metabolism is 5% or 50% of male pattern baldness, but after having run minoxidil and high dose caffeine and the way it affects my scalp I’m certain it plays a role (in my case)
Children with expanded foreheads have the least hair in the front. Even young girls with giga expanded foreheads are nw2-3
it’s totally possible that a theory is correct without it being the biggest contributor to male pattern baldness
