It depends on how dark your current color is and how light you want to go. Try using 30 volume. It's strong enough to do the job but won't kill your hair the same way a stronger developer would, as long as it's used properly. If you're hesitant, try seeing a stylist.
I would use at least 20 volume, since you're going for a lighter color. Good luck!
you use 20 volume developer on gray hair
you need a 10 or 20 developer. Nothing higher. Since your going from light to dark you dont need to use a strong developer to lift color out.
for pre colured hair if dark brown you can use 2 no less colur with 30 vol and streaking powder
depends on if you are going lighter or darker. If darker use a 10 if lighter use a 20
Use a 5N (Neutral) + 10 Volume developer. If there are any grays present, mix color with 20 Volume instead.
No, it would be preferable to use 20 volume developer when going from dark brown to black hair color.
I would recommend a darkish highlight or something that stands out.
If your hair is naturally dark brown and has not been colored, use 20 volume.If your hair is colored dark brown, you will have difficulties trying to lighten it to the desired level and may need to visit a hair salon for a corrective color consultation.
30 volume developer, or peroxide, will successfully lift naturally dark brown hair, resulting in nice highlights.
Mixing any volume developer with shampoo will have absolutely no affect on the hair. If you're interested in lightening the hair, the developer will need to be mixed with bleach.
It should turn brown if you use a Level 5N or lower with a 10 vol. cream developer.
Depending upon the desired amount of lift, 20 or 30 volume developer should be used when lightening the hair. 20 V. will lift 2 levels and 30 V. will lift three levels on virgin hair. 40 Volume is not recommended.
