dht is not the cause of hair loss . the way finadteride works is by ihnhibiting dht to stop the inflamation and the regrowth is due to the new elevated free estrogen levels (more estrogen with dutasteride so more regrowth and sides) .i think the way swisstemples regrew his hairline buy using a pgd2 inhibitor to stop inflamation(sulfasalazine) with huge sucess is a good proof .even with equol we can inhibit much more dht but we dont get regrowth due to the same estrogen levels ,regrowth is much harder to achieve , even maintenace requares at least some minoxidil pge1 or other pge2
How much does finasteride reduce dht in scalp/ follicle and serum?
Finasteride reduces TGF beta expression in the scalp by 30%, could this be the hidden reason why finisteride works
