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.
The only way to make a 20 volume would be to mix equal parts of 30 and 10 volumes.
Yes, if mixed equally, a 10V + 30V= 20 Volume developer.
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.
The volume can be found by multiplying the three dimensions (depth, width and height) together. So the volume here is: 10 x 10 x 20 = 2000 square feet.
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.
Mixing 10 and 20 volume developers in equal amounts will yield a 15 volume developer.
The only way to make a 20 volume would be to mix equal parts of 30 and 10 volumes.
Equal parts of 10 & 30 V. developer will yield 20 v.
you can't mix developer with developer to make another developer
Yes, if mixed equally, a 10V + 30V= 20 Volume developer.
Yes, combining ''equal parts'' of 30 V. and 10 V. developers will make 20 V. developer.
Mixing equal parts of 20 V. and 40 V. developers will give you an approximate 30 volume developer.
What is the difference between 10 and 20 volume creme developer?
No, 20 volume developer will not darken hair by 3 shades. It will lift & deposit when darkening or lift 2 levels when going lighter. If you're interested in darkening hair by 3 shades, choose a color that's 3 shades darker than you want to be. You can either mix with 10 volume or 20 volume. Mixing the dark color with 20 volume will be the most favorable as this will deposit deeper (due to the lifting of the hair's cuticle layer). This will help the color not to fade as quickly as it would if 10 volume were used.
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.
