no, manufacturers instrustions tells you not to
20 Volume Peroxide (or developer) is required for coloring white hair. It lifts & deposits in one step.
No, No you cannot. .... no you can't- but you can mix 10 with 30 volume! These strengths would equal 20 :)
Yes, cream peroxide is developer.
Does peroxide cream developer ever go bad? I have used the same one for over 3 years.
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.
Cream developer alone will not lighten your black hair. You will need to use a bleach or lightener with the cream developer to lighten it.
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
Cream peroxide developer is used by hairstylists. It helps to lighten the hair so that a brighter shade of dye can hold better. The number 30 refers to the level of intensity.
30 Volume Cream Developer is generally used for high-lift color, blonding, and bleaching.
If mixed equally, you will get 30 Volume.
Every company has a different quantity of peroxide that they mix with their colours. You will need to find that out.
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.
