COR.restore Leave-In Treatment is formulated to protect, repair, and strengthen coloured hair. Powered by chromaGard™ and AminoChain Technology™, it delivers 11 essential amino acids that help seal the cuticle for a smooth, glass-like finish while locking in moisture, enhancing elasticity, and reducing breakage. The result is hair that feels stronger, sleeker, and visibly healthier. Best suited to damaged, dry, or frizz-prone hair that needs extra strength, hydration and repair.
