I have highly bleached (nearly platinum) blonde hair. My natural color is a dark blonde to light brown. I want to dye my hair a medium auburn color. I have a few different box colors I picked up and wonder if there is a combination that will work. I have a Natural Instincts Dark Blonde, a Garnier Nutrisse Med Golden Mahogany Brown, and a Garner Nutrisse Ultra Color Light Intense Auburn. I was thinking of using the Dark blonde N9 as a filler and than the Golden Mahogany as the second step. Will this work since Dark Blonde is a Neutral?
