1:2 of peroxide and water
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.

Yes, you can dilute 30 volume peroxide to 20 volume by mixing 2 parts of the 30 volume solution with 1 part of distilled water. This will reduce the concentration of the peroxide while maintaining the desired volume strength. Be sure to mix well before use.
No, the higher the developer number, the more drastic of a color change it will provide when mixed with dye. 20 volume is generally used to change the hair about two shades, if you would like it more dark or light, use a 30 or 40 to get about 4 shades away from the gray.
It is not recommended to double the volume of developer to achieve the desired strength. Using a 10-volume developer when a 20-volume developer is needed can result in uneven hair color or ineffective processing. It is best to use the correct developer volume for the hair color you are using.
Equal parts of 10 & 30 V. developer will yield 20 v.

Yes, you can create a 20 volume solution by mixing 30 volume and 10 volume solutions. To achieve this, you need to mix the two in specific proportions. For example, mixing 1 part of 30 volume with 2 parts of 10 volume will yield a solution that approximates 20 volume. This is because the mixing of hydrogen peroxide concentrations results in an intermediate volume based on the ratios used.

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.

To prepare 3% hydrogen peroxide from 30% hydrogen peroxide, you need to dilute the 30% solution with water. The formula to calculate the dilution is C1V1 = C2V2, where C1 is the initial concentration (30%), V1 is the volume of the initial solution, C2 is the final concentration (3%), and V2 is the final volume of the solution you want to prepare. By plugging in the values, you can determine the volume of 30% hydrogen peroxide needed and the volume of water needed to achieve a 3% solution.

At least a 20 Volume, 6% peroxide should be used for lifting. Although, the hair tone can still be changed with 10 Volume, 3%. Using this however, you will not see much lift.
To make a 20 volume developer using 10 volume and 30 volume, mix equal parts of each (1 part 10 volume and 1 part 30 volume). This creates a balanced solution that averages out to approximately 20 volume. Alternatively, if you have 10 volume and 40 volume, mix 2 parts of 10 volume with 1 part of 40 volume to achieve the same result. Adjust the ratios to maintain the average desired volume if using different combinations.
30 volume developer, or peroxide, will successfully lift naturally dark brown hair, resulting in nice highlights.
The only way to make a 20 volume would be to mix equal parts of 30 and 10 volumes.
