It must be distilled water but yes. You can combine equal parts distilled water and 40 volume to get 20 volume developer.
mix 1 part of developer 30 with 0.5 part of water
Yes. 10 vol developer is 25% peroxide.
Applying hair color to WET hair will dilute the color somewhat OR add more developer than what is instructed to the mixture. For example, if a color mixture requires 2 oz. of color + 2 Oz of developer, add 3 oz of developer to dilute it.
The ratio is 1:1. So, 1oz of developer to 1oz of color.
The volume of the developer simply tells you how many levels it will lift your hair so since you are using 30 volume, it will lift your natural color 3 levels higher to help the permanent color show better. The volume/color ratio is 1:1 which means however many oz. of haircolor you use, you put the same number of oz of developer. For example: 2oz permanent haircolor: 2oz of developer I hope this helps you! Source: I am a cosmetologist
How many ounces of green soap do i dilute with water
i have the loreal technique preference permanent haircolor "natural black #3" and i dont know how much of 20 volume creme to mix it with.
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 dilute a solution, add water to it. To concentrate a solution, take water out of it.
Dilute acid is already a solution.
more dilute not less dilute. "Less Dilute" means more concentrated.
Water can dilute an ETG test. However, you will have to drink a large amount of water for the dilution process.
