I have used Henna to dye my hair for 2 months. I do not have much white hair, but a few at the very eye catching area (just above the forehead and near the ears). I like the reddish colour of Henna on my black hair, but the white hair turned gold (which made it even more eye catching). I used indigo to mix with Henna last night. My hair turned black and the white hair disappeared. When I look at it carefully, it is actually dark brown or even a little bit green. It becomes invisible with the black hair. I think I will use Henna next time and see whether it will go back to the reddish colour, hopefully without the few pieces of golden hair.
