I have some experience with dyeing my hair. Copper tones, there are many, but not all deliver what they promise. By advertising I hear about the hair color. I thought I was doing something good, and my hair trying to too much chemistry to refrain in their hair. Exactly according to package instructions, I applied the paint. They could be applied well and not dripping. It also smelled better than other hair colors. So far so good. After washing out the color then came the nasty surprise. My natural hair color is dark blond and the lengths are still engravings from the previous color. After dyeing my hair was orange at the base and quite dark in the lengths. It was an extremely strong gradient. My luck in this case was that the color is washed out very quickly. After only one week I could see my approaches again. So much for permanent hair color.
My Conclusion: - Color result not as on the package - Strong gradient -> no uniform result - Color washes out again very quickly
