Trace minerals (calcium, zinc, potassium, etc.) are essential to proper health and functioning of the body. Typically trace minerals are stored in the body and then used when needed; excess trace minerals are pissed down the toilet if stores are exceeded. One one of the most important factors to hair loss in the lack of trace minerals, and through masturbation these trace minerals are ejaculated and then the stored amount are then used to regenerate the sperm and spinal fluid (30% of semen fluid stored in the prostate alone). Imagine if your body lacks proper trace mineral stores in the body, and you are constantly masturbating and replenishing your semen/fluid with whatever trace mineral stores your body has left. As trace minerals are needed through your whole body...you will indeed be causing harm as these necessary minerals will NOT be available for other bodily/cell functions. So in theory, there should be a correlation to hair loss when semen is discarded through masturbation. Nutrition is also an important factor. For example, phytates inhibit trace mineral absorption, and such phytates are included in oats, seeds, nuts, grains, etc. Surely animal based foods like meat or eggs have high levels of trace minerals, but on the contrary such foods increase Dihydrotestosterone (or DHT) levels which also inhibit hair growth causing hair loss. For those that eat a plant based diet, it is best to figure out the correct combo in foods which will fill your body with trace minerals, and while doing so keep doing that nofap so not deplete your trace mineral stores. A good alternative is to take a good trace mineral supplement while doing NoFap. But be very careful and do your research...as such supplements usually contain aluminium, lead, and arsenic. On the contrary for those eating a plant based diet, you can consume mineral absorption enhancers like garlic or onions with your trace mineral supplement, considering you will be eating phytates. A garlic or onion pill/extract will do the trick. Sorry for my first post being like this, as it is something that has been on my mind, and something I'm giving to others to think about as well if interested.
