30 vol is stronger
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.
Mix with 20 or 30 Volume Cream.
Equal parts of 10 & 30 V. developer will yield 20 v.
creme developer is thicker and more conditioning Also.......Clear developer is mainly used when coloring out of a bottle and cream is used when coloring with a bowl & brush.
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.
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
No, No you cannot. .... no you can't- but you can mix 10 with 30 volume! These strengths would equal 20 :)
Equal parts of 10V. Developer + 20V. Developer= 15 Volume Developer
What is the difference between 10 and 20 volume creme developer?
Redken Camo Color Developer is 20 volume.
you can't mix developer with developer to make another developer
you can but it will make your hair extremely orange or brassy. It would be better for you to use bleach with the 20 volume developer..20 volume does the least amount of damage to your hair..just be sure to build the strength of your hair back up with conditioning treatments.
