I have excessive masturbation/sex and hair loss and sensitive scalp to dht, what to do?

Internet garbage. There's a "pop" claim on the internet that sexual activity causes male hormone changes that accelerate baldness. This is made up, i suspect as someone's cruel prank. Plenty of celibate clergy are bald. How fast a man loses his scalp hair is genetic, and if you'll look around, it correlates with how much chest hair he was blessed with. To look good, stay in shape. Photo guy's not worrying.
