I’ve been using this regularly for 4 years now, after wanting a truly natural alternative to chemical dyes. I love the colour, my hair is naturally dark brown and I use this to cover greys, but it also enhances my natural colour beautifully - better than any expensive fake dye ever did. And no hint of red! Does take time, 3-4 hours developing for grey coverage, but you get used to it after using a couple of times, I also just use half a box every second and third time to manage greys, which cuts costs a bit. Wouldn’t use anything else now.
