30 volume developer will lighten the hair three levels.
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.
No, it would be preferable to use 20 volume developer when going from dark brown to black hair 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
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.
Pureology is definitely the best for volume and it won't strip your hair color.
It will remove the pigment from your hair and lift your hair color 3 times (lighten it).
To use peroxide volume 30 in hair, mix it with hair dye or bleach according to the product instructions. Apply the mixture evenly to the hair, making sure to avoid the scalp. Leave it on for the recommended processing time, then rinse thoroughly with water and follow up with a conditioning treatment.
It's not the volume of developer that determines processing time. The color line be used, the amount of gray present, whether you're lifting or depositing color, and the texture of the hair all determine processing time.
Yes, this will work, but I recommend using 20 volume developer instead of 30 volume and watch the hair closely.
Volume 10 peroxide is generally used for deposit-only color, while volume 20 peroxide can lighten hair by one to two shades. If you're looking to significantly lighten your hair color, volume 20 is more effective than volume 10. However, the degree of lightening also depends on the hair's starting color and condition. Always consider a strand test to see how your hair reacts.
Adding Ardell Unred to 30 V. developer will not have any affect on the hair. Unred is made to be mixed with both hair color and developer, not developer alone.
A 5 or 10 volume developer are best for darkening, or depositing, hair color.
