How do the rice protein and the keratin fixing balm change the coloring result and hair feel?

The rice protein in the cream dye isn't just a label claim — it acts as a film-former that helps the color pigments adhere more uniformly across each strand, especially on porous or previously colored lengths where pigment tends to grab unevenly. The practical result is a shade that looks more saturated and luminous, with fewer dull or patchy zones. After rinsing the dye, the included fixing balm delivers keratin (a structural protein naturally found in hair) plus vitamins directly to the freshly colored cuticle. At this stage the cuticle is slightly raised from the alkaline dye process; keratin helps it lie flatter, which reduces the rough, straw-like texture many people experience after permanent coloring. Flatter cuticles also mean better light reflection, so the copper-red tone appears clearer and more even. For anyone who colors regularly — every 4–6 weeks — using this balm each time can cumulatively improve manageability and reduce the cumulative dryness that leads to breakage at the ends.
