Wella Illumina 4/60 ml hair color is a professional hair dye designed to achieve naturally looking, dimensional color results. This permanent hair color offers rich, long-lasting coverage with a focus on maintaining hair health and shine. The 60 ml tube contains enough product for a complete application on medium-length hair. Formulated with advanced color technology, it ensures even color distribution and reliable gray coverage while preserving the natural hair structure and condition. The Illumina series is known for its radiant finish, enhancing the natural light reflection of the hair and creating depth and dimension instead of flat, opaque color. This shade 4 represents a medium brown tone with natural undertones, suitable for various skin complexions. The ammonia-based formula allows for effective color penetration, while the integrated care system helps protect the hair during the coloring process. Application requires mixing with the appropriate developer according to professional guidelines for optimal results. The creamy consistency ensures easy application and minimal dripping during use. Suitable for both salon professionals and experienced at-home users who understand the correct hair coloring techniques. Always perform a strand test 48 hours before full application to check for color compatibility and potential allergic reactions. Store the product in a cool, dry place away from direct sunlight to maintain product integrity.
