Complementary colors work well together, such as a red shade and a brown shade. Avoid mixing together contrasting or opposite shades, such as blonde and black.  You only need to mix colors if you want a particular shade that isn't available or just enjoy creating a custom color. If you want an easier option, you can look for a pre-mixed shade, such as a red-brown, a brown-red, or a blue-black. Contrasting shades will be too dominant to work well together, while similar shades can complement each other nicely. The 2 colors need to be from the same brand. This will ensure that the colors combine well, as the formulas will be similar. It will also ensure that the same ratio of dye to developer is required. Colors that you are mixing together need to have the same developing time to work effectively. Check the instructions on the back of the box to make sure that the time required for each is the same. When you are picking colors to mix together, keep an eye on the number that is with the color formula. The higher the number, the more that it will be able to lighten your hair. Try to keep the 2 colors within the same 2-3 shades. For example, one shade that's slightly darker and one that's slightly lighter than your natural color works well. Make sure that you use the exact same amount of each shade. This will ensure that the color is uniform throughout your hair.  Using a 1:1 ratio of the 2 colors also means that you can easily replicate the color later if needed, such as if you want to dye your roots at a later stage. If you want to mix your dyes in a different ratio, write down the formula you create so that it's easy to replicate. This will be especially helpful when you want to touch up your roots! Use a small set of scales to weigh out the shades if you aren't using a full unit. Mix together the 2 different hair dyes that you have already combined, and then add the developer. Combining 2 shades together will double the amount of hair dye that you have. This means that you will need to calculate the right amount of developer to mix this with.  For example if the ratio for your hair dye to developer is 1:1, then you will either need to double or triple the amount of developer that you use. If you bought boxed hair dye, then your developer is likely already included in the box. You shouldn't need to purchase it separately. Check the product label to see if it's included in your kit. Include the brand and full color and number combination that is written on the dye box. This means that you can replicate easily in the future if you want to dye your hair again, or if you need to touch up the roots. Even if you weren't happy with the final look of your mixed hair dye, writing it down will ensure that you don't accidentally repeat the combination in the future.
