Garnier Olia No Ammonia Permanent Hair Color is a revolutionary hair dye that transforms the coloring experience by combining vibrant, long-lasting color with a nourishing, ammonia-free formula. Unlike traditional hair dyes, Olia utilizes a unique blend of 60% natural flower oils including sunflower, camellia, and passion flower oils to color deep into the hair fiber without the use of ammonia. This oil-powered delivery system not only ensures rich, radiant color but also leaves hair feeling visibly healthier, hydrated, and up to three times shinier than untreated hair.
