Hello. Thank you for writing to us at healthcaremagic Masturbation / self stimulation has no effect whatsoever on hair loss. It is a myth that masturbation accelerates hair loss. Masturbation is an absolutely normal human behavior. Having said that, the act of self stimulation should be in moderation and you should not over indulge in it so that it should not hinder you from carrying out your daily routine activities. Regarding hair loss, androgenetic alopecia is the most common cause of hair loss in males. It is gradual. There is a positive family history in most. Involvement predominantly affects the front and vertex of the scalp. There is gradual thinning and decrease in hair density. There may also be gradual recession of anterior hair line in this type of alopecia. Minoxidil and finsateride have approval for use in this type of alopecia. It is important to start therapy as soon as possible to prevent/ slow down further progression. I suggest you to visit a dermatologist for a confirmatory diagnosis and appropriate treatment. Regards
