How do the rice protein and keratin fixing balm affect the color result and hair feel?

The rice protein in the cream dye works during the coloring process itself: it helps the hair fiber hold onto more pigment, so the Dark Chocolate 3.0 shade comes out deeper and more luminous rather than flat or dull. This is especially noticeable on mid-lengths and ends that tend to grab color unevenly. After rinsing out the dye, you apply the included fixing balm, which contains keratin (a protein naturally found in hair) and vitamins. Keratin fills in microscopic gaps in the cuticle created by the alkaline dyeing process, so the surface feels smoother and reflects light better — giving that glossy, polished finish the shade is known for. The vitamins in the balm add a light conditioning layer that reduces post-color roughness without weighing the hair down. Together, these two steps mean you get both the color intensity of a permanent dye and a noticeably softer, shinier texture than you would with dye alone. For best results, leave the balm on for the full recommended time before rinsing; skipping it or rinsing too early reduces the smoothing effect.
