If a man suffers from hair loss and he took a supplement that increases testosterone naturally would more testosterone mean more dht?

Dubious stuff: Pop claims about baldness, testosterone, DHT, and supplements involving either is rubbish, much of it made up out of whole cloth. A man's hair loss is basically programmed genetically and expressed when there's enough of the right hormone around. Even If you get the effects on muscle / erections you want from a supplement, which seldom happens, hair loss is unlikely to accelerate.
