Redken

Acidic Bonding Concentrate 24/7 Night & Day Serum

This leave-in serum is designed to visibly strengthen and shield hair from daily aggressors using a blend of squalane and citric acid. The lightweight formula provides grease-free moisture and enhances light reflection for a shinier, more lustrous appearance. It acts as a protective layer to limit breakage and can be applied day or night to provide high-grade protection and a natural reboot.
