Olaplex No.0 Intensive Bond Building Treatment 5.2 oz - Prepares, strengthens, and protects hair across coily, curly, straight, and wavy textures

Olaplex No.0 Intensive Bond Building Treatment is a professional-strength pre-treatment designed to prime hair for deeper repair, rebuild broken bonds, and strengthen strands from within. Formulated with patented OLAPLEX Bond Building Technology™, this intensive spray works on a molecular level to restore the integrity of damaged hair caused by chemical, thermal, or mechanical stress. When used as the first step in a two-part system with Olaplex No.3 Hair Perfector, it amplifies repair results by preparing the hair to absorb nourishment more effectively. The lightweight, easy-to-apply liquid saturates each strand for improved texture, resilience, and visible shine, leaving hair feeling softer, smoother, and healthier after every use. Suitable for all hair types, including color-treated and chemically processed hair.
