L’Oréal Paris Excellence Crème Permanent Hair Colour 5.1 Profound Light Brown is a salon-quality at-home hair dye that delivers a cool-toned, natural-looking light brown shade with 100% grey coverage. It’s powered by L’Oréal’s Triple Care System, which includes 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. This ammonia-free formula ensures a gentle application while enhancing shine, softness, and resilience. The result is long-lasting, multi-tonal colour that looks radiant and healthy for up to 8 weeks.
