20 Volume Peroxide (or developer) is required for coloring white hair. It lifts & deposits in one step.
To make a 40-volume developer, you would mix equal parts of 20-volume (6%) hydrogen peroxide cream developer with another equal part of 20-volume (6%) hydrogen peroxide cream developer. This will give you a total volume of 40 (12%).
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.
Powder bleach alone will not lighten hair without cream peroxide. Cream peroxide is necessary to activate the bleaching process and lighten hair effectively. Mixing powder bleach with cream peroxide creates a powerful bleaching agent that can lighten hair several shades.
Mixing 10 volume cream developer with 40 volume cream developer could result in an unpredictable reaction, potentially altering the intended chemical properties of the developer. This could affect the color result and the effectiveness of the hair color product. It is best to use the developer recommended by the hair color product manufacturer for optimal results.
No. Rinse is a temporary color. 40 volume developer is used for high lift color, lifting more than 4 levels. When you apply 40vol to your hair, you are lifting the cuticle layer of the hair, difusing pigment inside the cortex and preparing for lift. This causes a certain amount of damage to the hair. It would not be a good idea to use this for a rinse. I would suggest seeing a professional if you want good results. There is a reason professionals go to school to learn these things :)

Which developer you use will depend on the color you want to achieve. A 20 developer will give you a darker color than a 30 or 40 developer.
If the target color is only one level lighter, use 20 volume. If it's more than one level, use 30 volume. 40 volume is generally not recommended and should only be used by experienced professional hair colorists.

no, manufacturers instrustions tells you not to
Every company has a different quantity of peroxide that they mix with their colours. You will need to find that out.

A creme developer is used on the hair to help lift and tone the color. The developer will speed up the lightening process of the hair and is typically used when bleaching or highlighting the hair.

Salon Care 10 volume cream developer does nothing for the hair when used alone. When mixed with a color, it will deposit color into the hair and when mixed with a lightener, it will lighten 1.5 levels.

Does peroxide cream developer ever go bad? I have used the same one for over 3 years.
