The author seems to suggest that the size of bones in the male skull causes extra scalp tension that in turn causes dihydrotestosterone to accumulate in the areas affected, eventually resulting in fibrosis and male pattern baldness. He seems to also suggest that estrogen causes the bones to become smaller and e.g. the brow bossing to decrease, and to also cause the muscles in the scalp to lose strength, resulting in loosening of the tension, which results in increased blood flow and significant regrowth.
To be honest, if I read the article correctly I feel a bit leery about the premise. It would be rather wonderful if taking estrogen would cause the skull to become smaller and more feminine... but has anyone seen this happen?
If anyone else has read the article and has a different interpretation of its meaning I'd be interested in hearing it.
