Worried about hair loss ㅠㅠ

As you get older, isn't hair loss something everyone worries about?

I'm not yet at the point of being bald, but I'm still worried about the increasing hair loss.

I used to pride myself on being quite smart in my youth.ㅜ

Now, I can feel that the crown area is gradually looking a bit more sparse.

Are there any good foods or injections to reduce hair loss?
