L'Oreal Paris Prodigy Hair Colour in 1 Obsidian offers an intense, deep black shade that delivers a rich, multidimensional color with a natural-looking finish. The ammonia-free formula uses innovative Micro-oil technology, including nourishing Argan oil, to infuse color into each strand while enhancing shine and smoothness. This color lasts up to 8 weeks, providing 100% gray coverage and a vibrant, radiant finish. The formula not only delivers long-lasting color but also improves hair texture, leaving it feeling soft, nourished, and looking healthy without harsh, brassy undertones.
