Most receptors in the body are sensitised/upregulated as far as I know by simply getting too much or too little of the hormone they react to.
With age, testosterone production drops. Also, SHBG production increases, which binds free testosterone and makes it inactive.
Therefore we end up with less total T and far less free T.
So... the androgen receptors in our scalps (among other places) are not getting as much free T as they expect to get (typically the amount they would get when we are say 20). Therefore they become more sensitive. Which impacts the hair follicles, as we are familiar with.
And that's my theory, lol
I'm not sure why SHBG increases with age. Maybe it's in response to increasing estrogen or something, as I know that can increase with age (a weak liver can apparently cause it, for example).
Perhaps if one can increase their free T to the level expected by the receptors, yes at first you'd lose more hair but then they might calm down and you might stop losing hair completely, regrow, etc.
Interested to hear your thoughts!
