A haircolor question? Which will bring better results, mixing a 6.0 with a 7K (copper) or a 7.0 with a 6K?

Answer 1

It depends on how light or dark you want the color. If you have more of the 6.0 than the 7k, it will be lighter than the other formula. How much copper/red do you want in your hair, and how light or dark is the natural or pre-colored hair. It all works together. With out a picture of how you look now, and an idea of where you want to go, I can't help you.

Answer 2

It would look pretty much the same since they are the same level. 7 is one shade lighter than 6.
