hi! I dyed my hair with l'oreal colorista #denimhair semi-permanent hair dye. it's a dark greenish blue colour now, after more than 1 month. I wanna dye it brown (idk when but before january). will a 3.0 dye cover it? at the roots it's already gone but it's cool, it looks like a balayage. should i wash the ends "harder" so it fades away before dying it? thank xx(the photos are not mine, they just look alike my hair)
At the current shade would suggest nothing lighter to cover then using a dark reddish brown. The red tones in dark reddish brown to balance/help neutralize the green/blue. When trying ot cover a natural color over a vibrant color always suggest fading the blue/green in this case as much as possible. The lighter the blue/green is before dying the easier will be to cover the blue/green. These are my suggestions and opinion.
