What is the difference between 10 and 20 volume creme developer?
Equal parts of 30V + 40V= 35V.
Mixing equal parts of 20 V. and 40 V. developers will give you an approximate 30 volume developer.
Quick question how long do you let it sit there before doing the dye?
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.

Any brand cream developer can be used with a color as long as it is mixed according to the manufacturer's directions and it is the appropriate volume.
