A creamy, luxurious daily shampoo designed to transform everyday haircare into a moment of pure indulgence, leaving hair irresistibly soft, and shiny. Infused with nourishing Roucou oil— a precious extract from the Amazonian Achiote plant, known for its high concentration of antioxidants, beta-carotene, and vitamin A, which help reduce damage from external aggressors and treatments, contributing to a silky hair effect.
Ideal for any hair type, especially frizzy, damaged, or even healthy hair in need of extra care, the soft, velvety lather gently cleanses while delivering intense hydration and boosting natural shine. The rich, detangling texture leaves strands silky, manageable, and visibly full-bodied, with a strong cosmetic effect that can be felt from the very first use.
Each wash leaves hair delicately scented with a warm, lasting fragrance—for an aromatic experience that lingers.
Hair feels pampered, radiant, and deeply loved—soft, shiny, and ready to shine.
