Dying my hair back to it's natural color?

I have had good luck with Garnier Nutrisse haircolor, if your hair is a natural dark brown, then make sure you stay away from anything that has the word golden in it.. that could turn your hair red. If the word ash is in the name it tends to be kind of blah.. try to stick with the natural colors. Without seeing your hair, I can't be for sure, look through the swatches if there are any at the store, or look on the top of the box, I have found it to be a good indicator to go on, remember, whatever color you choose will be a little darker to begin with but will lighten up with a few washings. Make sure you get a good conditioner too, because color treated hair does require more moisture. Good luck!
