Equal parts of 10V. Developer + 20V. Developer= 15 Volume Developer
Yes, the appropriate volume developer must be mixed with any Matrix color.
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.
Equal parts of 30 volume + 40 volume developers= 35 Volume Developer.
Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
Redken Camo Color Developer is 20 volume.
Which developer you use will depend on the color you want to achieve. A 20 developer will give you a darker color than a 30 or 40 developer.
Mixing 10 Volume developer and 40 volume developer will never make a 20 volume regardless of how much is mixed. In order to make a 20 volume, equal parts of 10 and 30 volumes will need to be mixed. Mixing 10 and 40 will make 30 volume.
Mixing equal parts of 20 V. and 40 V. developers will give you an approximate 30 volume developer.
