I currently use Robert Craig hair color which somewhat "coats" my hair without lift. I am about 70% gray on front and sides, and 50% in back. My hair is dark brown, thick and long and I have used a mix of coffee brown and golden brown. I don't want to continue to use it, and I would like to try yours. I have about one inch of new gray growth and would love to know where do I begin? Can I put your color over Robert Craig?
