Hi, I have a client who has a natural level 7 root and bleach highlights on the ends. She wants to go back to a medium brown. I know that you have to fill the hair but she doesn't have much red tone in her natural hair so I'm really reluctant to pre-pig using red. Do you think it would be ok to use 7/03 in Wella colour touch to fill the hair and then use 5/0 colour touch as my final colour. My thinking is that the red tones in the 5/0 is enough to not make it go that horrible khaki colour but not enough to be a red toned brown? I'm trying to go for a natural brown as possible without using any Ash tones as I know that will turn it green. I just don't want to see over whelming red/orange tones. Also I'm thinking 5/0 because although it may be initially dark, it will fade out really quickly and go slightly lighter, more to a level 6 which is what I'm aiming for. Thanks in advance much appreciated.
