Let me clarify something, I do not believe that a particular diet will produce or prevent Androgenetic Alopecia. I have seen no research that demonstrates this.
I did assume that you were referring to the Australian aboriginies, The term Aborigines can refer to any indigenous people, but I assumed that, if you were talking about Native Americans, that you would have preceded the word ''Aborigines'' with a regional description such as ''North American Aborigines''.
As far as the main causes of Androgenetic-Alopecia, (male pattern baldness) they are pretty simple.
The main cause is a genetic predisposition to Androgen Receptor sites which are located on the hair follicles of the human scalp-which are preprogrammed, (by your genetic profile) for eventual apoptosis, . It's that simple, DHT is one of the main androgens which triggers hair follicle cell apoptosis in these people.
To paraphrase:
Your genetic profile loads the gun, DHT and other male androgens pull the trigger....
Gotcha..except why would we lose our hair in such a pattern if all the follicles with the exception of the hair on the sides of head is programmed to be sensitive to DHT and fall out, why would it not all start falling out at the same time?? Like I said before it falls out exactly the same way it grows in pretty much. This has to be explained.
I saw a hair loss specialist a few years ago and he thought that it was more you scalps sensitivity to DHT than it is the actual hair follicle. He said that the DHT cause your scalp to tighten which then cuts off blood circulation to the hair follicle slowly killing it over time. So indirectly yes your follicles are sensitive to DHT, however if you scalp were to remain loose enough enough blood would reach the follicle, thus preventing hair loss in the first place.
It would be interesting to know like I said before the straw that broke the camels back so to speak in terms of body signals and knowing the exact moment that our bodies decide to start shedding that very first follicle, and why it is after being able to sustain resistance to DHT, did this then cease and hair loss begin in the odd pattern that it does.
The lack of blood flow to the scalp theory is dead, if this were the case all vasodilators would cure Androgenetic Alopecia. Not to metion, the oubvious fact, that if you had enough of a lack of blood flow ,to the scalp, to cause your hair to fall out your scalp tissue would die from a lack of blood rich oxygen and circulation!
Also the scalp itself does not have adrogen receptors the hair follicles do, so that theory about DHT tightening the scalp is invalid.
The reason that all of the hair doesn't fall out at once, is due to the fact that hair follicles gradually minaturize over time, and the hair growth cycles become shorter, as each new cycle begins the hair shaft that emerges is minaturized this process repeats itself until the hair shaft eventually dies, and no longer returns because of cell apoptosis.
The rate of hair follicle minaturization is ultimately predetermined by your genetics, which varies with each person.
Babies hair growth has nothing to do with Androgenetic Alopecia, as you can see people who don't have Androgenetic Alopecia have the same type of hair growth as a baby as those who do. There is no correlation here. Besides, a babies hair growth does not always mimic male pattern baldness, it may resemble it because a babies hair grows in gradually so it appears thin and whispy at first, correlation not causation...
At least this is where we will hear about it first. Far to many smart people investing far to many hours for it not to be so. I would rather hear from you. Why do you think he mentioned the people from Central American Rainforest along with those with a genetic defect and Native Americans?
