What is the verdict on hairloss? Blood flow or genetics?

[Esquire Janey]

Epigenetic changes could possibly impact and either improve or worsen baldness. As a practical matter, it is all but entirely based upon genetics. I have seen identical twin pics who differ somewhat in the stage of baldness but that's not that common. If one identical twin goes skin bald then the other one has a phenomenally high probability of also being completely bald. Penis size might be similar in this aspect.

Under this reasoning, however, estradiol appears to be able to invoke enormous change in things previously dominated by male receptors. Thus, estradiol epigenetically turns off the male baldness gene, but this occurs along with every single indicia of masculinity from head to toe, especially the breasts and genitalia immediately changing tissue composition. Men and women's skin per se differs enormously and the skin changes come all but immediately. The hair is the least responsive thing to HRT for many people which might mean that balding areas have enormous numbers of hair receptors to which androgens tightly cling. It could take a decade or longer for long-term estradiol use to reverse baldness, the most prominent form of sexual dimorphism among humans I expect.

Scalp tension, mainly due to tight muscles surrounding galea and less blood PRESSURE to get through ( yes the scalp has loads of blood if you cut it, this disproves nothing ) inflammation then DHT then hair loss follow in that order.

So basically your galea is injured and inflamed under the skin as it's being pulled down by tight muscles around the sides. There is less blood pressure on route to galea hair follicles malloclusion may play a part here also.

Like anywhere on the body, DHT arrives at the site of inflammation. It's a simple google to confirm this well studied fact. it's no different with the scalp, hence hair loss.

At this stage I'm staggered most people think it's down to genetics, unless of course that's the genetics of having a huge galea, poor posture, mouth breather, tight temporalis or whatever is the main culprit for someone's tight scalp.

But the arguement that some people have some specific hair that is prone to attack from DHT, is 'genetics' is bonkers. It doesn't half make a lot of money though.

But DHT specifically promotes hair growth in most mammals so something fascinating is happening. So call it what one may, DHT appears to be very highly associated with turning off scalp hair growth in XY's while promoting beard growth and body hair growth. I don't deny your theory at all in terms of etiology but the circular question is why doesn't this happen to most white females and practically no Asian or Native American females? But regardless as to whether DHT is really a healing factor, the only thing that seems to cure the follicle is not DHT or T. It's estradiol.
