Higher androgen levels and site-specific ARexpression cause sex-related skeletal differences, and certain steroids can boost ARexpression and androgen effects in bone cells.
The phase 3 trial results for Pyrilutamide showed no significant difference from the control treatment in increasing hair count, leading to the company halting its development. Users discussed their disappointment and skepticism about hair loss treatments, with some mentioning other treatments like Minoxidil, Finasteride, and RU58841.
Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.
The conversation discusses the mechanism of action of alfatradiol (17 alpha estradiol) in treating hair loss. It explores theories that it either inhibits 5 alpha reductase to prevent T->DHT conversion or aromatizes scalp T into 17-alpha-estradiol to save hair.
The user experienced male pattern baldness starting at 18, tried finasteride with no success, and switched to dutasteride, which halted hair loss. Minoxidil had no effect for them, while their brother, who didn't use AR inhibitors, maintained a juvenile hairline and successfully grew a beard with minoxidil, highlighting the unpredictable nature of genetics in hair loss and treatment response.
The conversation discusses why DHT (dihydrotestosterone) negatively affects scalp hair but promotes growth elsewhere on the body. Various opinions include genetic predispositions, differences in hair follicle reactions to DHT, and the potential role of Omega-3 in reducing inflammation and promoting hair health.
