My client had a full head of highlights bleach + 6% with Majerel 8.0 in between foils 2 weeks ago. She has now contacted me and has said that she feels it is a bit too blonde for her and would like to add more of the base colour, level 8. Can I just go in with more foils with the 8 or should i go in a shade darker. Also would i be better off using Dia Richesse instead of Majerel. thanx
