Phyto Paris Permanent Color 666 Intense Cherry Light Brown is a professional hair dye that offers rich, long-lasting color with optimal hair care benefits. This permanent hair color in an intense cherry light brown shade combines warm reddish undertones with a sophisticated light brown base for multidimensional color results. The formula contains plant-based ingredients such as soy proteins and vitamin E, which protect the hair during the coloring process while maintaining its natural shine and softness. Each application provides complete gray coverage with consistent, predictable results that last through multiple washes. The ammonia-free formula minimizes scalp irritation and ensures even color distribution from roots to tips. Suitable for all hair types, including normal, dry, and colored hair, this coloring system includes both color cream and developer for professional at-home use. The product develops its vibrant color within 30-45 minutes at room temperature, with precise timing instructions for optimal results. The packaging contains 60 ml of color cream and 60 ml of developer, sufficient for medium-length hair. An allergy test should be conducted 48 hours prior to application according to the instructions. The color maintains its intensity for 4-6 weeks with proper hair care and gradually fades to natural tones without drastic color changes. Phyto's commitment to botanical ingredients ensures that this hair coloring respects the hair's natural balance while providing reliable, salon-quality color performance.
