Hi. I have a news client who has shoulder length white hair. She has grown out colour on the ends. She would like golden low lites. I use L’Oréal. I am thinking to use 9.0+ 9.3, 8.0, and perhaps 7.0+7.03( would the 7 mix be to dark? I haven’t worked with such white hair before. Many thanks. I will upload a photo.
