To create a 30 volume developer solution with a 40 and 30 volume developer, you can mix equal parts of each developer together. For example, mix 1 part 40 volume developer with 1 part 30 volume developer. This will result in a 35 volume developer solution, which is close to 30 volume. It is important to perform a strand test before using the mixed developer on your hair to ensure it is the desired strength.
