The Kerastase Densifique Densité Shampoo & Conditioner Set is designed for fine, thin, and thinning hair that needs extra volume, strength, and shine. This duo gently cleanses the scalp to remove build-up while nourishing from root to tip, leaving hair visibly thicker, fuller, and more resilient. Formulated with Hyaluronic Acid, it helps improve scalp hydration while strengthening hair fibers for a denser, healthier look. The shampoo purifies and adds body, while the conditioner deeply nourishes, detangles, and enhances softness and shine without weighing hair down. Ideal for those seeking lightweight volume, improved texture, and long-lasting fullness.
