After taking 6 months to grow out my gray to see how I'd like it (I didn't!), I started coloring my hair again. I use Robert Craig Chocolate Brown on my temples only (where I have the heaviest concentration gray), then I use henna over the whole head (including the temple area). I like that the henna gives my scattered grays a lovely red hightlight effect. The RC keeps the temples from being bright red bozo streaks from the henna. I'm very happy with this combination.
