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

Rice protein in the color cream works during the processing time. Its film-forming properties coat the hair fiber, creating a more uniform surface that allows oxidative color pigments to deposit evenly and lock in more effectively. The practical outcome: the shade looks more luminous and resists fading from washing slightly better than a formula without protein, especially on hair that feels rough or porous before coloring.

The fixing balm is applied after the color is rinsed out. At that stage the cuticle is still open and the hair is at its most vulnerable. Keratin — a protein naturally present in hair — fills microscopic gaps in the cuticle layer, while the vitamins and conditioning agents add slip and reduce friction. This means the hair feels less straw-like, combs more easily wet or dry, and reflects light more evenly, which is why the dark blonde tone appears more polished from root to tip.

For best results, leave the balm on for the full recommended time (usually 3–5 minutes) rather than rinsing immediately. If you color regularly, using a keratin-rich mask once a week between colorings extends the smooth feel and color vibrancy.
