Olia Hårfarge 1.0 Night Black
Product Insights
Olia Hair Color 1.0 Night Black, a permanent hair dye from L'Oreal Norge AS, delivers an intense, long-lasting black shade. The formula is ammonia-free, gluten-free, and includes conditioning agents that help maintain hair softness and shine after coloring. Nevertheless, it contains the typical hair-dye sensitizer p-phenylenediamine (PPD) and other fragrance compounds that can irritate sensitive scalps, so a patch test is essential.
Comparative Analysis
Positioned as an ammonia-free, gluten-free permanent hair dye that offers deep black coverage with built-in conditioning, Olia 1.0 Night Black differentiates itself in the crowded market through L'Oreal's patented pigment technology and a focus on reduced scalp irritation.
