10
darker!
depends on if you are going lighter or darker from your original hair color. if lighter do a 20 if darker do a 10
Which developer you use will depend on the color you want to achieve. A 20 developer will give you a darker color than a 30 or 40 developer.
Mixing 20 and 30 volume creme developer will create an unknown volume of developer that falls between 20 and 30. This mixture may alter the expected results when used with hair color products, potentially resulting in unpredictable color outcomes or hair damage. It is generally recommended to use the developer volume specified by the hair color product for the best results.
To lift or make lighter you want to use, 30, and 40 Valium developer. To darker you use 10 and 20 Valium developer. Also to go lighter use a hair dryer. For darker room temperature. Colour should never be left in the hair longer then the time recommended, it over processes and the fades much fast.
It is not recommended to dilute hair developer by adding water as it can alter the effectiveness of the product. It's best to use the developer at its intended volume for optimal results.
For 1 part hair color and 2 parts developer, you should mix them in a 1:2 ratio. This means using twice as much developer as hair color. Ensure you measure accurately and mix well for best results in coloring your hair.
Mixing hair bleach with water will dilute the bleach, reducing its effectiveness in lightening the hair. The mixture may not lighten the hair as desired and could lead to uneven or patchy results. It is generally recommended to use hair bleach with the appropriate developer for best results.
I would say it depends on your hair type and what kind of developer you used
It appears there may be a typographical error in your question. Assuming you are asking about using a hair color cream with a clear developer, it is important to note that the developer plays a crucial role in activating the hair color molecules and determining the final color result. Using a clear developer with a hair color cream may not provide the desired results as the developer needs to have a specific volume (strength) to effectively lighten or deposit color on the hair. It is recommended to use the developer specifically recommended for the hair color cream you are using to achieve the best and desired outcome.
The ratio of 40 volume creme developer to permanent hair color is typically 1:1. This means you would use the same amount of developer as you do hair color. For example, if you mix 2 ounces of hair color, you would also use 2 ounces of 40 volume creme developer.
A 10 volume creme developer is a type of hydrogen peroxide solution used in hair coloring or bleaching to lift the hair color by one level. It is a gentle developer that is suitable for deposit-only color, toning, or color correction with minimal lifting. The "volume" refers to the strength or concentration of the peroxide in the developer.
