Yes, developer (also known as hair developer or peroxide) must be mixed with hair dye or bleach to activate its lightening properties. It usually comes in different volumes (like 10, 20, 30, or 40) that determine the level of lift or lightening. Always follow the instructions provided with the hair color or bleaching product for the correct mixing ratios. Mixing developer with any other products not intended for hair coloring can lead to unpredictable results.

No.
To make 10 volume developer from 20 volume developer, you can mix equal parts of 20 volume developer and distilled water. For example, mix 1 part of 20 volume developer with 1 part distilled water to create 10 volume developer.
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.
Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
No, diluting a 30 vol hair developer with water will not change the volume strength of the developer. To make a 20 vol developer, you would need to mix the 30 vol developer with a neutralizing solution or a lower volume developer.
20 volume
You have to have a actuall hair color to mix with it. Use 2oz of the color and 4oz of the developer and mix. And apply to your hair
To make a 40-volume developer, you would mix equal parts of 20-volume (6%) hydrogen peroxide cream developer with another equal part of 20-volume (6%) hydrogen peroxide cream developer. This will give you a total volume of 40 (12%).
To create a 14 volume developer from 10 volume and 20 volume developers, you can mix them in equal parts. Specifically, combine 1 part of 10 volume developer with 1 part of 20 volume developer. This will yield a 14 volume developer, as the mixture balances the strengths of the two developers.
Mix equal parts of developer and Wella color.
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.
