If a person has male pattern baldness from DHT, would masturbating or excessive masturbation make it worse?

There is no evidence to suggest that masturbation (mild or excessive) or sexual activity causes hair loss.

The simple answer to this is NO. There is no link between masturbation and hair loss. To find out more about your hair loss and seek out a solution to your hair thinning, you should meet a Dermatologist and get a proper diagnosis.

Neither sex nor masturbation causes balding. Men's testicles make testosterone and this is metabolized into DHT, a male hormone 40 times as powerful as testosterone. When a person has genes for balding, the hormone DHT works with the gene to cause balding. The body makes an enzyme that allows for the manufacture of DHT and this enzyme can be blocked with the drug finasteride to often stop and possibly slow down the balding process because this DHT hormone production drops.
