Same old story with trying to prove that masturbation causes anything:
Medically, you can't separate masturbation from sexual activity with a woman. And sexual activity with a woman is considered not only non-harmful, but GOOD. Nature wants like hell for us to get laid every chance we get. So nature literally couldn't make masturbation damaging or else we wouldn't survive as a species.
Case closed.
I'm not saying that masturbation causes hair loss, but your post makes no sense. Nature also wants humans to eat food. But some foods are harmful, and now developed countries are facing obesity epidemics. Nature wants us to be weary of potential threats to our lives, and yet excess stress harms us as well. And nature wants every species to flourish, and yet look what human overpopulation is doing to the environment. So I think that an excess of sex OR masturbation could only be bad. Everything in moderation.
