Garnier Olia Permanent Coloring 1.10 Black Sapphire offers a deep and sophisticated black thanks to its innovative oil-powered formula, ammonia-free. Enriched with four natural flower oils, this dye guarantees not only an intense color with a sapphire reflection but also a nourishing treatment that makes the hair fiber visibly softer and smoother. The coverage of white hair is a full 100%, for a uniform and long-lasting result of up to eight weeks. The application is simple and clean: the handy mixer and included gloves allow for precise dosing of the mixture and protect the scalp from potential irritations. The smart packaging reduces the risk of leaks, while the delicate floral fragrance transforms the application phase into a true moment of sensory well-being. Ideal for those who want an intense black with a professional effect, Black Sapphire enhances every hair type, giving extreme shine and sparkling reflections. Perfect for a touch-up at home, it ensures salon-quality results without compromise.
