Well, I am not going to suggest any remedies, drugs or anything similar here. But I would like to tell you my own story. I stopped my own hair loss after I stopped fapping. Yes, indeed. There are several threads on different forums telling similar experiences and not to mention that almost half of those belong to the NoFap communities and the NoFap Subreddit.
I used to believe that fapping only causes hair loss in men, but now after stopping to fap myself, I have discovered that not only was it giving me hair loss, but was responsible for increasing my testosterone levels to borderline, decreasing my estrogen levels and last but not the least, this addiction of mine was also responsible for giving me a PCOS.
The great news is that I am free of all that since I stopped fapping.
