Bodybuilders and male models. Why is there no hair? Do they shave every day? Doesn't shaving often make your hair grow more and more?

This is caused by genetic factors.

It is said that men of the purest Han descent have smooth skin and less hair. Men of Mongolian descent have more hair. It is inevitable that our country was once occupied by Mongols. Think of Japan ...)

You can take estrogen if you don't want to shave, but don't eat too much.
