I'm 21 years old and jerk off 3 times a day for 5 years. My hair in the middle is going down (Photo)

In my opinion, masturbation is not the cause of your hair loss. You need to visit a hair expert and determine the etiology. They will do a good history and a magnified examination. Should you have a genetic hair loss, there are good treatments. Minoxidil and finasteride as well as low-level laser are FDA-approved for this indication. We have had excellent results in treating young patients with platelet rich plasma. We have seen an increase in hair thickness, decrease hair loss and some hair regrowth. Hope this helps. Good luck.

It is not clear why you believe masturbation is causing your hair loss. You should see a doctor if you're concerned.

It is normal to masturbate and this will not impact your hair loss. Your biggest enemy is the
progressive thinning leading to a balding pattern that is not evident at this
point in time. The degree of thinning that you are showing would suggest that
you should see a doctor who most likely will get Bulk Measurements of your hair
to determine the degree of the thinning that you are presently having. If the
diagnosis is early genetic hair loss, then the best treatment would be the drug
finasteride which is highly effective in men of your age and may not only stop
the hair loss but possibly reverse it. If you are developing a more advanced
balding pattern the best test to get will determine the Bulk Measurements of
your hair and this will show, over a one-year time frame, how effective the
treatment will be. Once you know this information, then you and your doctor
need to develop a MASTER PLAN which will define what you need to do over the
years to come.See video below
