The La Puissânce Soft Liss Kit Essential Duo brings together two essential steps for achieving smooth, frizz-free, and manageable hair in your daily routine. This set includes a shampoo and a treatment, both specially formulated for straightened hair or hair frequently exposed to flat irons and blow-drying. Powered by plant-based Maxiliss, phytokeratine, and jojoba oil, the formula gently cleanses while deeply hydrating and helping to repair the hair fiber. It delivers intense shine, softness, and thermal protection against heat styling tools, while helping to prevent hair aging and keep strands looking healthier and straighter. The shampoo and treatment work together to reduce frizz and humidity, strengthen the hair fiber, and maintain a sleek, polished look. Simply apply the shampoo to wet hair, massage gently, and rinse. Follow with the treatment, leave on for 2 to 3 minutes, and rinse thoroughly. Suitable for daily use. Paraben-free and cruelty-free formula.
