I am wearing a 1B piece and need to darken it to match my black sides and back and mainly to get rid of the brown hue under lights and sun but at the same time dont want it too black or else it'll stand out. If I leave the black dye in 1/4 of the time stated on the box will it be enough to get rid of the brown hue under lights? Also does anyone here use Semi-Permanent black dye? Can u suggest some brands please.
