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.
Equal parts of 10 & 30 V. developer will yield 20 v.
Equal parts of 10 & 30 V. developer will yield 20 v.
It won't make it 30. The way developer works is 10 is no lift deposit only and makes hair semi permanent. 20 is 7-10 shades of lift with deposit and makes hair colour permanent.

No, doubling the 20 volume creme developer will not give you the same results as using 40 volume creme developer. The strength of the developer impacts how much lift or color deposit it provides, so it's best to use the recommended developer for your desired outcome.
2.6 oz of developer.
Not much.
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.
Redken Shades EQ should be mixed with Redken Shades EQ Processing Solution. This line does not require 30 volume developer.
this sight sucks
When using Matrix SoColor with a 20 volume cream developer, the typical mixing ratio is 1:1, meaning you would use equal parts of the color and the developer.

Always refer to the specific instructions on the product for any variations or adjustments needed based on desired results.
