21 ng/dl DHT is not even minuscule. Ofc it is lower than most male but I have very high sensitivity to DHT. Yes it was coincidence, I have been thin before and I haven't had hair loss without shedding and the hair loss used to look different than now. Also now I have oilier skin, more and thicker body hair and different sweat odor so yeah I know it is upregulation also I told you my androstenedione lowered while DHT increased.damn it must he just coincidence that ur hair got worse when u started losing weight, it definitely has to be your miniscule dht levels
