Redhead going white and gunmetal-gray in patches.

I use mahogany henna about once a month. $3 worth (half of a $6 box) is good for one application on my thin baby-fine hair. Nice thing about the henna is that it leaves golden highlights where my white hair is, rich red highlights where my red hair is, and deep mahogany highlights where the gunmetal-gray is. So it doesn't really change the look of my hair, just the color tone. And it gradually washes out over the course of the month, so as my hair grows there really aren't any "roots" to speak of.

Tried letting it go natural a few times, and I looked like I had bald patches. My hair is just too thin. When my whole head is white or white-with-scattered-red-strands (like my Grandma's, our hair is similar) I'll let it be.
