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.
Usually 30 volume peroxide is mixed with lightener for blonding purposes. Or for lifting 3 levels with color.
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).
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
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.
A 5 or 10 volume developer are best for darkening, or depositing, hair color.
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.
No, it lifts your natural hair color by use of the developer. The higher the volume of the developer the more lift you will get in your hair.
