First the positive: The coloration has convinced me by their ease of processing and its pleasant smell. Negative: A review that certified the great color, I tried my standard hair color chocolate brown and could not believe my eyes when I washed out the hair: they were red, as if I had got lost in the reds, which truly is a with my dark brown hair feat was. Therefore, a total of 3 star: 5 stars for ease of use 1 star for the way too much red in chocolate brown.
