I'll be 50 this year and don't have a whole lot of gray, yet. My mother has this beautiful white hair, of course that grew in after her Chemo 25 years ago.
I have naturally blond hair, but it has gotten a darker the past few years so a good friend of mine weave's it for me, to "lighten" my life up a little!! With my blond, I don't think the gray shows up a whole lot.
