Dht as an intracrine and paracrine hormone

[goolapsh]

I’m just curious: is it the high blood serum dht concentrations, or is it the higher free t from scrotal cream that contributes to hairloss, or is it a combination. A doctor on a particular Facebook group suggested that dht is more intracrine/paracrine, and so serum dht is essentially meaningless. I disagree, but I’m not an expert.
