Hi MSCherokee
Well, I haven't a gray hair yet. It's not for lack of trying.
Host/Comedian Jay Leno is now mostly gray with a dark strip. When he first hosted the Tonight show it was reversed. Dark with a gray strip.
What does that mean? I don't know. That is just what I have to offer on the subject. Hopefully more helpful responses will follow.
BTW, where in OH are you? I'm just east of Cleveland.
