I have a client who has been having L'oreal Supreme 7.34 for some time and the time has now come to change to Inoa Supreme because of it being discontinued. Unfortunately I haven't been able to get 7.34 in Inoa Supreme so am changing the colour to 7.32. On reading the instructions it says to do a colour change you need to do the roots in the new supreme colour and then the mid lengths and ends in an inoa reflects shade. I am a little confused as called L'oreal and they told me to just put the new colour over the whole head but am very concerned about the mid lengths and ends and am thinking they could come out darker than the roots and don't think the instructions are totally clear as why not say for colour change do a whole head tint. Has anyone any experience of doing a colour change in Inoa Supreme?...
