Finally, one day, I was ready. The more the gray came in, the more I loved it. I was at the point to commit to the full-on gray, and the lighter shades had set the stage with my natural grays woven into low lights, like a welcome mat. I just went for it.
I wanted to be 100% me, full-on Gray. This transition was not easy.
