I still don't have much gray hair on my head, though I do color my hair since it's gotten "mousy" and doesn't behave very well. As a result I color it with a color close to my original color. I notice after a few months, that the hair around the front of my ears (sidebangs) is whitish (I'm age 56), and so I color it again. Yeah...I've done the plucking thing too!
My main reason, though, for coloring, is because of the manageability. Coloring gives more body, and I keep my hair rather short.
On a different note! My vaginal hair started turning WHITE in my early 40's, around the time I experienced early menopause....Not a concern for me, but I do notice it is mostly white now!
