John, all that I can say is the following: Leave it natural man! Don't get me wrong, the just for men works for some brothers, but believe me, I use to have grey hair all up on my dome, I never thought about dying it just because it works if you are confident with it. Its distinguished, denotes wisdom. I've got red hair in parts of my black beard, I do not doubt that it is only a matter of time before I end up grey their as well, but when I'm rocking the Goat in those future days, I will probably rock it the O-Natural way... Bold, Natural, Sly... Thats the way I like to play it.
