hi there, i have a client that has a natural shade between 3/4 and wants to go to a 6/07 (koleston perfect)
Would i be right in thinking a 9% developer would give me the lift required, or should i use 12%. It is on virgin hair.
Thanks guys not been doing coloring for long and always like a little reinsurance.
