If you mix equal parts of 20 vol and 40 vol, you will have 30 vol, which is slightly stronger than 20 vol and slightly weaker than 40 vol. 40 vol should never be applied without help from a professional as it may damage your hair.
Mix equal parts of the 10 vol. and 20 vol. developer to create a 15 vol. developer solution. This will give you a balanced formula that combines the properties of both developers to achieve the desired volume strength.
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.
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.
20 vol is what ya need for color it has "regular" lift just enough to deposit color...30 vol is "extra" or high lift for a more extreme lightening. Be very careful using 30 vol on scalp it is very strong stuff :)
At a pressure of 1,013 bar and a temperature of 0C: 4,61 vol. chlorine in 1 vol. water.
To make a 20 vol peroxide solution from a 40 vol peroxide solution, you need to dilute the 40 vol solution by mixing it with an equal amount of water. This will effectively reduce the concentration of the peroxide solution by half, resulting in a 20 vol solution.
Equal parts distilled water & 40 vol peroxide.
Mix equal parts of the 10 vol. and 20 vol. developer to create a 15 vol. developer solution. This will give you a balanced formula that combines the properties of both developers to achieve the desired volume strength.
sphere volume = (4/3) * pi * r^3 vol = (4/3) * pi * 20^3 20^3 = 20*20*20 = 8000 vol = (4/3) * pi * 8000 vol = 33510.321638291127876934862754981
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.

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

10 anytime your going darker unless you looking for gray coverage, then 20
