this dude Mitko really got me looking at everyone's galeas for the past few months, and needless to say i am on board. however, my research and experimentation with hormones leads me to believe that these two causes of hairloss are not mutually exclusive, but it is incredibly interesting to realize how fucked the foreheads and top of the skull are of pretty much every norwood 7. the mongoloid skull type seems to be far less prone to growing in a way that is detrimental for scalp hair. i theorize that possibly due to the skull shape, dht and testosterone may get trapped in the parts of the scalp that are most susceptible to androgenetic alopecia (temples, crown, vertex), and develops overtime at the rate of skull expansion
the only possible way to reverse this is, as we know, by systemically removing dht from the system, and the best way to do this is to overtake it with E2. call it broscience but the fact that galea is clearly an influence, it makes sense that HRT can be so successful in hair recovery if the problem is the inability of the scalp to flush problematic hormonal remnants. additionally, HRT stops or greatly slows expansion of the skull, which in adult years is influenced by testosterone
