Good idea, but unfortunately that won't work. There's no way to make a 40 volume, you will need to buy that separately.
Mixing equal parts of 20 V. and 40 V. developers will give you an approximate 30 volume developer.
Mixing a 30 volume creme developer with a 40 volume creme developer is not recommended as it can alter the desired outcome of your hair color process. The resulting mixture may have an unpredictable volume, potentially causing damage to your hair and scalp.

Mixing 20 volume creme developer with 40 volume creme developer can result in an intermediate strength developer solution, depending on the ratio of each.

It's best to use the developer strength recommended for the specific hair coloring product being used.
It is not recommended to double the volume of developer to achieve the desired strength. Using a 10-volume developer when a 20-volume developer is needed can result in uneven hair color or ineffective processing. It is best to use the correct developer volume for the hair color you are using.

The ratio of 40 volume creme developer to permanent hair color is typically 1:1. This means you would use the same amount of developer as you do hair color. For example, if you mix 2 ounces of hair color, you would also use 2 ounces of 40 volume creme developer.
