Coworker with hair loss. Should I get involved?

Are you being serious? No, you should not approach him about his hair loss. He might not care at all, in which case you will be perceived as nosy and rude. If he is self conscious about it, he doesn't want you bringing attention to it. He has the Internet, if he's worried about it there is a plethora of publicly available information for him to find on his own.
