Kerastase’s Anti Rigidity Decalclfying Repairing Conditioner targets the heavy, rigid feel caused by calcium build-up, using citric acid to gently decalcify so hair looks cleaner, lighter, and more responsive. Wisteria amino acids help repair and reinforce the fiber, supporting Premire strength for strands that feel healthier and less prone to stiffness. The lightweight, hydrating formula restores suppleness, smooths the cuticle, and visibly reduces frizz while adding shine without weighing hair down. Fine to medium-thick hair gets the most noticeable lift, though all types benefit from improved manageability from root to tip, with a softer touch and easier styling. With continued use, hair stays flexible and polished, trading dull rigidity for a smooth, resilient finish.
