It will lift colour three levels above a base 6 (dark blonde) and it lighten hair two levels below a base 4 (brown).
10 Volume developer has a minimal amount of lift and is not recommended for lightening hair. Try using 20 or 30 volume instead.
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.
No, developer alone, (despite the volume), will NOT lighten hair. It will only open the cuticle. In order for lightening to occur, either cream, powder, or oil bleach must be added.
Equal parts of 10V. Developer + 20V. Developer= 15 Volume Developer
Equal parts of 30 volume + 40 volume developers= 35 Volume Developer.
Equal parts of 5 volume developer + 15 volume will yield approximately 10 volume.
Yeah i use 30 percent volume when i have 40, measure it just say it weighed 1kg. take away 25% of it. :)
Redken Camo Color Developer is 20 volume.
you can't mix developer with developer to make another developer
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.
40 Volume developer is not recommended to use when bleaching hair as it is very strong and can cause major damage if not done by a professional. 20-30 volume would be better and safer for home use.
Mixing equal parts of 20 V. and 40 V. developers will give you an approximate 30 volume developer.
