Yes, it is possible.
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.
I am a hairstylist and have never heard of peroxide 6 percent. Normally peroxides come in 10vol 20vol 30vol and 40vol. If you are going darker or trying to cover greys you use a 10vol. If you are trying to achieve a lighter look you would use the other three volumes 20-30-40. The difference between them is how long you want your hair to process and what level of lightness you want to achieve. The higher the volume (30-40vol) processes your hair faster and can get it lighter. I would recommend using a 20 volume to start if you want to lighten. It is a safe way to start out. 6% peroxide is also known as 20 volume developer as 3% is 10 volume, 9% is 30 volume, and 12% is 40 volume. Also......for gray coverage...always use 20 volume. 10 volume will NOT cover gray hair.
Mix equal parts of 50V.+10V. to yield 40 V. developer
Their physical properties are similar except for that hydrogen peroxide is 40% denser.
Equal parts distilled water & 40 vol peroxide.
Equal parts distilled water & 40 vol peroxide.
3 parts 40 vol to 1 part water

It depends on the volume of developer. 10 vol = 20 mins 20 vol = 30 mins 30 vol = 40 mins 40 vol = 45 min
No and its surely poison sharjk says I have used it for a year i seem to think it is whitening my teeth but i use 40 vol
flashlightning 30 vol. or 40 vol.

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!!
No! I am a licensed cosmetologist, and no hair color will cover gray with 40 vol. you must use 20 vol only if you want 100% gray coverage. Period!!!!!!!!!!!
