I have a client who had level 2 roots and really light ends. However she wanted to get rid of the dark roots so her hair was all the same colour. I used Blondor & 12% on her roots along with Olaplex. It left a gold halo all the way round her head..her roots were light & the ends were light but the mid lengths were ginger. I've since used Blondor & 12% another twice and this halo still won't budge...Can anyone give me any suggestions & advice on what I'm doing wrong and how to help?
