Mumbo Jumbo! Mumbo Jumbo!
Yes for men that have dht sensitive hair lowering their dht will slow the rate of hair loss and make some salvagable hair stronger causing regrowth.
But you are missing the point. A man with a full head of hair can have higher dht levels than a man that is balding. The significance is whether or not your hair is sensitive to dht. Masturbation isn't going to effect your hair for **** sake.
If a man who has the genes for balding, such as a higher sensitivity to DHT or a greater amount of AR receptors in the scalp is subjected ,to higher levels of DHT than he should have, would he not start the process of balding? The issue depends on levels of DHT when someone abstains from masturbation to someone who doesn't. Yes, some people who masturbated everyday, for multiple times, never suffer from male pattern baldness but that could be due to a lower sensititivity to DHT. In these people who could also be seeing a higher level of DHT.
Now, I'm not saying that this is the truth, but there is not enough research to prove either side of the argument. Why would someone want to show any research which shows a bad effect of masturbation?
