Yes, you can use a 30 volume developer instead of a 20 volume developer, but it will lighten the hair more dramatically and may lead to more damage. A 30 volume developer is typically used for significant lifts, while a 20 volume developer offers a gentler option for less lift and is better for covering gray hair. Be sure to adjust your processing time and consider the condition of the hair to avoid potential damage.
No, doubling the 20 volume creme developer will not give you the same results as using 40 volume creme developer. The strength of the developer impacts how much lift or color deposit it provides, so it's best to use the recommended developer for your desired outcome.
20 vol
The difference between the volumes of developers is that 20 volume gives 2 shades of lift, and 30 gives 3 shades of lift. If you are coloring you your hair darker than your natural hair you want 20 volume and also if your only going up 2 shades of your natural color you would use 20.
To cover gray hair and dye brown hair dark blonde, it's recommended to use a 20 volume creme developer. This strength provides enough lift to lighten the hair slightly while also covering gray effectively. Be sure to follow the instructions on the hair dye kit for best results.

When used alone, developer will do nothing to the hair. It is made to be mixed with a hair color.
Mixing a 20 volume creme developer with a 30 volume creme developer will result in an intermediate volume of developer, likely somewhere between 20 and 30 volumes. The resulting volume will depend on the specific ratios of the two developers that are mixed together. It is important to note that altering the volume of developer can affect the outcome of hair color or chemical treatments, so it is recommended to use the developer volume specified in the product instructions for best results.
