Give your hair a professional strength reset with Olaplex No.0 Intensive Bond Builder, a potent, spray-on treatment designed to revive dry, weakened strands from root to end.

Powered by Olaplex’s patented Bond Building Technology™, this priming formula helps repair visible signs of damage by rebuilding broken bonds within the hair. The lightweight liquid saturates each strand for maximum absorption, boosting hydration, improving strength, and supporting smoother, shinier, healthier-looking hair.

Suitable for all hair types, No.0 is your essential first step for an at home, salon grade repair ritual.

Use 1–2 times per week, depending on your hair’s level of damage, for visibly stronger, more resilient strands.
