I've been trying to respond since Friday but the site was wonky.
Have you looked into Color by Robert Craig? It seems to fit all your criteria. Hair Color and Hair Care by Robert Craig Salon Products, Ltd.
Whatever brand you choose, be sure to select a color that is 2-3 shades lighter than your natural color, as most all brands go darker on curly hair. I would suggest a dark brown to start, you can always go darker but it's hard to lighten up a mistake.
