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
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.
To dilute 20 volume hydrogen peroxide to make a 3% solution, mix 1 part of 20 volume hydrogen peroxide with about 6 parts water. This will result in a 3% concentration of hydrogen peroxide. Remember to handle hydrogen peroxide carefully and wear appropriate protective gear.
This means that for every volume of hydrogen peroxide used, 20 volumes of oxygen will be produced. For example, if 1 ml of hydrogen peroxide is used/decomposes, 20 ml of oxygen will be formed.
20 volume peroxide comes from a beauty supply store. Try Sally's.
The strength of a solution may be described as a percentage or volume, where 1% hydrogen peroxide releases 3.3 volumes of oxygen during decomposition.Thus, a 3% solution is equivalent to 10 volume and a 6% solution to 20 volume, etc. Answer taken from Wikipedia 19/01/2009

Equal parts distilled water & 40 vol peroxide.
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.
10 anytime your going darker unless you looking for gray coverage, then 20
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, 10 is half as weak as 20 volume.. if you mix them equal parts you'll get a weak 15 volume...if you need 30 volume and only have 10,20 mix your color with just less than 2 parts 20 as in 1 oz color 1 3/4 oz 20 volume this will give you just less than 40 but it will be soupy...just spend the money and get 30. hope this helps.

it's 1:1.5 (dye to peroxide) for the ash blondes :)
Yes, you can dilute 40 volume peroxide by mixing equal parts of 40 volume peroxide and water to achieve a 20 volume solution. For example, mix 1 part 40 volume peroxide with 1 part water to create a 20 volume peroxide solution.
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.
To dilute 20 volume hydrogen peroxide to make a 3% solution, mix 1 part of 20 volume hydrogen peroxide with about 6 parts water. This will result in a 3% concentration of hydrogen peroxide. Remember to handle hydrogen peroxide carefully and wear appropriate protective gear.
If you mean OREOR® Creme Developer and other brands the main difference is the name on the bottle. For the most part the ONLY difference between developers is what strength (Volume) the developer is. Standard developer is 20 Vol. (6% peroxide) they have Extra Lift 30 Vol. (9% Peroxide) High Lift 40 Vol. (12% Peroxide) And Low Lift 10 Vol. (3% peroxide) and No Lift 5 Vol. (1.5% peroxide) and each is used for a different purpose - Gray coverage, high lift tints, bleaching, streaking/highlighting, tint backs, semi permanent colors and toning. And as long as the correct Volume is used they are interchangeable. That being said: Dedicated Developers are recommended because they have the correct consistency (thickness) special conditioners and or buffers and correct pH for the product being used. All of which can improve or enhance the product performance. For example: most Creme Haircolors DO NOT have a thickening agent in them like most liquid or gel colors so, if you use a developer that is too thin or liquid it will make the product runny. Also, if your color requires a certain pH to give the proper result using any other developer may result in less than ideal hair condition or may cause premature fading. Hope This Helps. Good-Luck!!
