Matrix's Instacure Build-a-Bond Super Sealer Leave-In Conditioner (100 ml) is an innovative hair treatment designed for very damaged hair. Infused with citric acid and squalane, it strengthens hair fibers, smooths strands, and controls frizz for up to 72 hours. It protects against heat up to 230°C (450°F), while detangling and conditioning without weighing hair down. Its leave-in formula works deep down: 1 billion bonds are created per bottle. Apply to towel-dried hair before blow-drying; do not rinse.
