This is a professional-grade, semi-permanent hair color formulated by L'Oreal Professional under the DiaLight system. It is designed to deliver rich, visible tone-on-tone results without significant lift, offering a gentle way to refresh, enhance, or modify existing hair color while caring for the hair fiber. Ideal for all hair types needing a gentle, long-lasting color deposit, this formulation is perfect for blending grays or adding dimension to natural or colored hair. The semi-permanent nature ensures gradual fading without harsh root lines.
