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.

Is it 30vol or 20 vol you mix with a permanent color?
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 :)
What is the difference between 10 and 20 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.

How do you use peroxide 6 percent on 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.
Can you use 40vol peroxide and shampoo to strip your reddish brown dye out your hair?
Mixing any volume developer with shampoo will have absolutely no affect on the hair. If you're interested in lightening the hair, the developer will need to be mixed with bleach.

Why does the amount of hydrogen peroxide used determine how light your hair color is?
Its not the volume as in the amount, Its the volume as in the percentage 10vol would be less than 40vol. higher the vol the lighter and faster it lightens..remember faster is not always better..damage damage damage........

Can you make 20 vol peroxide from 30 vol and 10 vol?
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.
