First and foremost, the root argument of whether masturbation is beneficial or harmful for overall health is in itself highly debatable. Think of masturbation as a chemical reaction that unleashes a plethora of hormones and proteins and activates millions of neurotransmitters.
What Causes Hair Loss?
Genetic hair loss or alopecia is caused by the interaction between your genes, your testosterone (and DHT levels), time, and stress. 5α-dihydrotestosterone (DHT) is a male sex hormone, an androgen whose imbalance or metabolic changes can cause hair loss.
Normally, after ejaculation, the body triggers a testosterone-to-DHT conversion in the prostate and testicles. When DHT circulates and reaches the scalp and if your scalp is DHT-sensitive, excess DHT buildup can affect the hair follicles and their roots.
Other important factors include stress and steroid-related toxins that increase the activity of 5-alpha reductase, leading to greater testosterone-DHT conversion. Excessive amounts of the amino acid L-arginine, in conjunction with a high level of androgen hormone, can over excite the nervous system causing excessive testosterone-to-DHT conversion that triggers a stress response.
Should You Stop Masturbating?
Ancient Ayurvedic texts detail semen (shukra) as being the purest form of the 7 bodily tissues (or dhatus). It is considered a source of the life energy (Ojas) that directly reflects on our immunity and aura. Many spiritually inclined people who undertake celibacy consider loss of this energy via sex or masturbation as a waste of vital life energy.
Masturbation is considered to assist in the healthy rejuvenation process of semen and if done without guilt, misconceptions and excess, it should help relieve stress, provide pleasure and recharge the sexual organs.
Considering all aspects, excess of any activity will create unhealthy imbalances in the mind, body, and soul. No activity or habit should overrule our senses, causing a serious lack of mind control. Guilt and misinformation can lead to stress than can adversely impact hair fall.
Hair fall is due to a combination of multiple factors including genetics, the effect of medications, DHT sensitivity, etc. And masturbation, within natural limits and for recreation, is NOT its root cause.
