L’Oréal Paris Excellence Crème Permanent Hair Colour 4.1 Profound Brown is a salon-inspired at-home hair dye that delivers a rich, cool-toned 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 natural and vibrant for up to 8 weeks.
