If women are okay with gray hair so should men be. I don't think hiding the gray hair does any good, the reasons for not hiring older people from what I understand the preference for younger culture because they don't have experience and are gullible and also the pay is lower. Dying one's hair ain't gonna solve those requirements by the hiring companies. And in addition, some people start graying as early as their 20s and never bother to dye it.
We're talking about physical perception, that's why people go out of their way to get plastic surgery, braces, wear makeup, etc, to impress other people. You can say how things should be, and what the ideal world should be. But the fact remains, physical appearance helps immensely, whether that person is qualified or not. Why do people put on a suit for a silly interview? Why can't I just come in with flip flops and shorts? Yeh the world sucks, you play the game in a way that gives yourself the best chance to win.
