This Level 5 fundamental shade provides true-to-color, natural light brown results with beautiful warmth and dimension.

The revolutionary formula replaces traditional ammonia with an oil-based delivery system, providing a pleasant, odorless coloring experience while offering up to 48% more shine, 43% less hair porosity, +20% scalp hydration, and 6 weeks of anti-dryness effect . The vegan, wax-free formula features a fluid texture that is faster and easier to apply, mix, and rinse compared to previous iNOA formulations.

Mix at a 1:1 ratio (1 tube color to 1 part developer) with iNOA Oil Developer 10-volume (3%), 20-volume (6%), or 30-volume (9%), depending on desired lift . For white hair coverage up to 70%, use the target shade alone; for 70-100% white hair, mix ½ target shade with ½ fundamental family shade at the same level for optimal coverage . Development time is 35 minutes at room temperature.

The tube is made of 95% recycled aluminum for reduced environmental impact . This product is intended for professional use only.
