I disagree to a degree. Some older people look a little strange with no gray. An example would have been Roy Orbison (no disrespect meant at all) with the face of a great-grandfather and jet black hair in his final years. Me - I'm in my upper 40's and my hair hasn't turned gray yet (a little weird - my younger brother has a lot of gray) but my beard is gray like a dalmation when I allow it: mostly white with lots of brown patches. That looks bizarre so I use Just For Men for beards. I think anything that looks natural and professional is okay, and I'm looking forward to some nice balanced gray to give me that "distinguished" look.
