My boyfriend is 22 and is quite noticeably balding on the top of his head. I’ve never said anything about it because I figured he was probably already aware and bringing it up would just come off as rude and hurtful. I really don’t care — sure, I like his hair, but that’s a very minuscule part of what makes him attractive to me.
Recently, though, he mentioned to me that he took creatine briefly while trying to bulk up for a role in a play where he had a shirtless scene. He said he stopped taking it pretty quickly after his doctor advised him to avoid that stuff. He said “I heard it can make you lose your hair and my hairline is already going a bit.”
Take a read of these post: https://baldingblog.com/combover-madness/ and here: https://baldingblog.com/goodbye-combover-hello-hair-with-photos/. Many men practice denial all the way from early thinning to complete balding as suggested here. Some eventually with the help of a wife or child, find out. I, for example, didn’t know my crown was bald until my oldest son (about 18 at the time) commented on my bald spot in the back of my head. When I became a hair transplant surgeon, my wife told me that it would be bad for business if I had a bald spot, so I fixed it. Some men just don’t pay attention while other deny it.
