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.
Almost always the mixture is equal parts developer and color. For example, 2 ounces of color + 2 ounces of developer.
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.
I believe 1.5 parts would be 1.5 ounces of developer to 4 ounces of color, which doesn't seem like enough developer. Double check the directions. Usually haircolor is either 1:1 or 1:2 ratio. I've never heard of 4:1.5 ratio.
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%).
Equal parts of 10 & 30 V. developer will yield 20 v.
Equal parts of 10 & 30 V. developer will yield 20 v.
Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
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.
Equal parts of 30 volume + 40 volume developers= 35 Volume Developer.
It won't make it 30. The way developer works is 10 is no lift deposit only and makes hair semi permanent. 20 is 7-10 shades of lift with deposit and makes hair colour permanent. You have to buy 30 volume developer from a sallys beauty supply but 30 is very dangerous for the hair it can damage it severly I recommend sticking to just 20 volume
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.
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.
It must be distilled water but yes. You can combine equal parts distilled water and 40 volume to get 20 volume developer.
To make 10 volume developer from 20 volume developer, you can mix equal parts of 20 volume developer and distilled water. For example, mix 1 part of 20 volume developer with 1 part distilled water to create 10 volume developer.
Redken Camo color is designed to be mixed with equal parts of 10-volume (3%) peroxide developer for natural-looking results.
