List Of Mixing Hair Color With Developer Ideas. The mixing ratio is usually 1:1, 1:1.5 or 1:2 (for an extra strong lightening effect). When used on its own, a developer will lighten the hair, but the color result won’t be good.

Pour in your developer and, using your tint brush, stir until your mixture is thicker and creamier. The most common way is to mix the developer with the hair dye in a bowl, and then apply it to your hair. The right combination of hair dye and developer will ensure that your hair is evenly colored and looking its best.
