Well the blonde got pretty brassy and the roots dark grey after 3.5months, which wasnt looking good, especially not for wanting to transistion the color to grey naturally. I found a silver that would stop the brassy blonde and give me a even color. So this morning I coloured my hair, silver grey, it is darker than I expected, but softer and no longer brassy, so now the hair will transistion more easily to silver grey.

Below is the before and after color.
