After long-term exercise, the androgen in the body rises sharply, and the hormone is then transformed into DHT, a toxic substance that can damage hair follicles, which leads to hair loss.

Because under normal circumstances, human hormones are at a relatively peaceful level, but after long-term exercise or strenuous exercise, hormone secretion will increase, muscles will become stronger, and male charm will also be shown.

But hair loss may also occur at the same time.

I hope my answer can help you!
