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.
NO. If you mix them in equal parts, that would give you 35 volume. To get 15 volume, mix equal parts of 10 and 20 volume.
20
10 minus -20 is 30.
30 - 10 k = 20
Equal parts of 10 & 30 V. developer will yield 20 v.
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.
No, you cannot make 20 volume developer using 30 volume developer. The concentration of the developer is fixed and cannot be altered by dilution. It is important to use the correct volume developer as specified in the instructions for the best results and to avoid damaging the hair.
Equal parts of 10 & 30 V. developer will yield 20 v.
To create a 30 volume cream developer, you will need to mix equal parts of 10 volume cream developer and 20 volume cream developer. Therefore, you mix 1 part 10 volume developer with 1 part 20 volume developer to achieve a 30 volume solution.
No, diluting a 30 vol hair developer with water will not change the volume strength of the developer. To make a 20 vol developer, you would need to mix the 30 vol developer with a neutralizing solution or a lower volume developer.
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.
To achieve a 30 volume developer solution, you can mix equal parts of a 20 volume developer and a 40 volume developer. This will result in a 30 volume developer solution.
The difference between 10 and 20 volume developer is the strength or potency of the developer. 20 volume developer is stronger and lifts the hair color more effectively than 10 volume developer. The choice between them depends on the desired level of lift and hair color result.
No, you cannot make 30 volume developer out of 40 volume developer. You would need to dilute the 40 volume developer with either distilled water or a lower volume developer to achieve the desired 30 volume strength.
in my time with color i found you can sometimes lift with a 30 volume if your hair is not too dark, the 30 will lift and deposit as to 20 and 10 only depositing the color.
20 or 30 Volume developer is recommended for blonding.
