according to this actual study, masturbation can indeed increase levels of DHT which causes hair loss.

A few things that should be pointed out:

• The study was performed over 30 years ago, with the article dating to 1976.
• There are no controls on sexually active men here.

I suspect that an active sex life will keep testosterone levels up and as DHT is a metabolic end point for testosterone metabolism, that means that DHT will rise. With that said, this does not mean that hair loss will result, and that is the point. The presence of DHT working on the genetically sensitive individual is what causes hair loss and I don’t believe that masturbation or regular sex will impact the rate of hair loss. Once again, I strongly believe that masturbating does not cause hair loss.
