The typical ratio for mixing hair dye is 1:1, meaning equal parts of color cream dye and developer cream. The volume of the developer cream (measured in percentages like 10, 20, 30, 40 vol) does affect how much lift/lightening you will achieve. In general, the higher the volume of developer, the more lift you can expect, but it can also cause more damage to the hair.
