My natural hair was an ugly dishwater blond and I've colored it for years. A group of women I went to high school with go on a trip together every year and I always take photos and one of us is gray. Every time I show my photos to someone, they ask who the older lady is? My Mom went gray and it was a yucky color so I know what mine would look like. My MIL had beautiful silver gray hair and if I could have that I'd go natural. I think darker hair seems to go to a prettier shade of gray.
