10 volume is if you want to go dark with color but with bleach 10 vol gives you one level of lift but if it seems slow to you use 20 volume, never use 30 vol or 40 vol on scalp it will irritate it.
you can't mix developer with developer to make another developer
Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
Yes, combining ''equal parts'' of 30 V. and 10 V. developers will make 20 V. developer.
Equal parts of 10V. Developer + 20V. Developer= 15 Volume Developer
you make equal parts if your using a 4 ounce formula with a 2oz color bottle you would use 1oz of 20 volume developer then 1oz water then 2ounces of color
Yes. 10 vol developer is 25% peroxide.

It depends on the volume of developer. 10 vol = 20 mins 20 vol = 30 mins 30 vol = 40 mins 40 vol = 45 min

It should turn brown if you use a Level 5N or lower with a 10 vol. cream developer.
You can easily make 20 vol from 30 by mixing it with 33.3% distilled water, but I wouldn't try making 20 vols from 10 unless you have a laboratory and the correct equipment to distill accurately. One can also use equal parts of 30 vol and 10 vol. You can easily use two identical glasses and eye out equal amounts. Add them together. Viola. Peroxide is unstable so be sure to store your new concentration peroxide in a capped brown plastic bottle. Also be sure to label it 20 vol.
Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
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.
10
Yes, if mixed equally, a 10V + 30V= 20 Volume developer.
Yes, combining ''equal parts'' of 30 V. and 10 V. developers will make 20 V. developer.
