Mixing equal parts of 20 V. and 40 V. developers will give you an approximate 30 volume developer.
Mixing 20 volume creme developer with 40 volume creme developer can result in an intermediate strength developer solution, depending on the ratio of each. However, it is not recommended to mix different volume developers as it may alter the desired results and could potentially be harmful to the hair. It's best to use the developer strength recommended for the specific hair coloring product being used.
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. It's best to stick to the developer recommended for your hair coloring product for best results.
Mixing a 20 volume creme developer with a dye that already contains developer may result in an overly strong developer concentration, which can be damaging to your hair. It's generally recommended to use developer specific to the dye you're using to ensure proper color development and hair health.
Equal parts of 10V. Developer + 20V. Developer= 15 Volume Developer
Mixing 20 volume creme developer with 30 volume creme developer will result in an in-between strength, usually around 25 volume. This may alter the expected outcome of your hair color or chemical process, so it's best to use the correct developer strength recommended for your specific hair product.

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.
Mixing 20 and 30 volume creme developer will create an unknown volume of developer that falls between 20 and 30. This mixture may alter the expected results when used with hair color products, potentially resulting in unpredictable color outcomes or hair damage. It is generally recommended to use the developer volume specified by the hair color product for the best results.
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.
To achieve a 30 volume developer solution, you can mix equal parts of a 20 volume developer and a 40 volume developer. This will result in a 30 volume developer solution.
The volume of the developer simply tells you how many levels it will lift your hair so since you are using 30 volume, it will lift your natural color 3 levels higher to help the permanent color show better. The volume/color ratio is 1:1 which means however many oz. of haircolor you use, you put the same number of oz of developer. For example: 2oz permanent haircolor: 2oz of developer I hope this helps you! Source: I am a cosmetologist
Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
To make a 10 volume developer solution from a 20 volume developer solution, you can dilute the 20 volume developer with an equal amount of distilled water. This will effectively reduce the concentration of the developer solution by half, resulting in a 10 volume developer. For example, if you have 100 ml of 20 volume developer, you would mix it with 100 ml of distilled water to create 200 ml of 10 volume developer.
