So, my hair has been dyed to a level 8/9 copper and I want to go back to level 7 copper with permanent color. Should I use a 10volume developer, or a 20 volume, or mix both to make 15 volume?
What option would give me the least fading possible and maximum color deposit?
Thanks for the help
 
A demi permanent would give you the most deposit and longevity because its not opening the cuticle so much
