After Midnight is our deepest, darkest blue hair dye—a rich, intense shade that transforms hair into a striking midnight blue. This color works beautifully on virgin, unbleached hair to create dark blue highlights, but achieves its most stunning results on pre-lightened hair. For best results, we recommend lightening your hair to level 9 blonde or lighter before application. If your hair has yellow tones, tone it first to prevent unwanted hues and ensure the true depth of After Midnight comes through. The darker your starting shade, the more the blue will read as highlights rather than full saturation. Perfect for those seeking a bold, moody blue that commands attention.
