KANEBO Lissage - Vogne Essence Lead 220g Treatment A guiding hair serum that softens and loosens the inner structure of coarse, stiff hair, conditioning it into a smooth, manageable, and supple state. Ideal when you want an extra-soft, silky finish. Formulated with hydrolyzed collagen (moisturizing) and a hair-softening ingredient (succinic acid). Use before applying a rinse-off treatment. How to Use: After shampooing, apply an appropriate amount evenly to the hair. Do not rinse. Layer a rinse-off treatment directly over it.
