L’Oréal Paris Excellence Crème Permanent Hair Colour 5.5 Light Mahogany Brown is a rich, radiant shade that blends warm brown with subtle mahogany undertones for a vibrant, multi-dimensional finish. Designed for 100% grey coverage, this permanent hair dye is powered by L’Oréal’s Triple Care System — a pre-colour serum to protect delicate strands, a Pro-Keratin-infused colouring crème for deep, even colour, and a post-colour conditioning mask enriched with ceramides to nourish and strengthen hair after colouring. The ammonia-free formula ensures a gentle application while enhancing shine, softness, and resilience. Ideal for those seeking a warm, elegant tone with salon-quality results, it delivers long-lasting colour that keeps hair looking healthy and luminous for up to 8 weeks.
