it's the DHT causing hair loss via its metabolite 3alpha diol
like I posted elsewhere today, the problem is the metabolism of DHT in 3alpha instead of 3beta diol predominantly. NO is androgen-mediated, as said in your quote. No "pre-procarcinogen" (or dedifferentiating) DHT no problem.
People who "don't believe in DHT = hair loss" only miss one step in DHT metabolism.
DHT makes more 3beta diol in healthy thyroid subjects, which is anti inflammatory and differentiating (= no hair loss)
