There is only one way that masturbation can cause your hair to fall out: if you believe it so much that, psychologically, it manifests in your body and occurs. Masturbation and sex have the same effects on the body. An orgasm is exactly the same whether it was caused by a partner or yourself. Your body does not know, or care, which one caused the orgasm to happen. Please do not believe all the silly rumors about the dangers of masturbation. Masturbating 3 or 4 times a day is excessive and may cause the skin to become sore or irritated so practice it in moderation. Otherwise, there is nothing wrong with masturbating.
