I am no longer a gray haired woman!!!
So far the color seems to have worked. I'm more of a strawberry blonde.... with a quasi-bad haircut.
The color guru I see in Red State has known me since we worked together at least 15 years ago... so, when I told her we should go for my "natural" color, she knew exactly what color to mix up.... the color my hair was when I was about 25 :).
