I have no personal feelings for oragainst Keanu Reeves hair butfrom observing a recent photo of him , could see that he definitely has areceding hairline and there were noticeable gray hairs in his beard. So ,chances are that he'd have at least a little gray on his head. Probably uses alittle tint or color - no harm in that. I'm sure it's common among men in thecelebrity world.
