CHI Bond & Repair

The CHI Bond & Repair line is an advanced repair system for hair damaged by chemical treatments, heat styling, or everyday wear and tear. Its key ingredient, Keratrix™ (along with other bonding agents), penetrates deep into the hair fiber to help rebuild the internal bonds between amino acids, strengthening hair’s resilience, elasticity, and durability.

From shampoos and masks to leave-in treatments and oils, the products in this line reinforce the cuticle, seal the hair surface, and protect against breakage and damage. The lightweight oil also provides thermal protection up to 450 °F (≈ 232 °C), helping to minimize heat-related stress from styling tools such as straighteners and blow-dryers.
