I've never colored my hair and I don't intend to start now. It has a certain amount of gray and is slowly getting grayer.
The thing that bothers me most with some of the gray hair is the texture not the color being different from my normal hair.
Another funny thing it seems to be a process of going gray, as I can find a hair that goes from brown to gray and back to brown again.
I don't keep up with hair fashion anyway as I've had my hair long & braided for many years. When I had it shorter ...many years ago... it always looked like I had be in a wind storm as my hair is very fine.
My hair has always grown very fast. Not sure how fast it grows now but as a teenager it grew about 6 to 8 inches in a year. I could go from fairly short hair to longish hair in one year. So for ease & neatness & being cheap, I braid. And for those reasons I wouldn't bother dying my hair either.
