Olaplex No. 0 Intensive Bond Building Hair Treatment – Prime, Strengthen & Repair Hair (155 mL)

Olaplex No. 0 Intensive Bond Building Hair Treatment

Prime your hair with this salon-inspired pre-treatment to set the stage for deeper repair. The highly concentrated formula targets damaged bonds, helping hair feel stronger and more resilient as the first step in Olaplex's two-part system with No. 3 Hair Perfector.

Designed for quick, targeted application, the bottle's nozzle delivers a precise stream where you need it most, so you can focus on areas that show the most wear—ends, mid-lengths, or highlighted sections.

How it works with No. 3

Use Olaplex No. 0 as the primer before introducing No. 3 Hair Perfector. Together, they form a pathway to improved structure and manageability across all hair types: coily, curly, straight, and wavy.

• Prime your hair for your deepest at-home repair with this salon-inspired pre-treatment that boosts the effects of No. 3 Hair Perfector.
• KEY BENEFITS: Intensifies repair results with No. 3; strengthens hair and reduces breakage; rebuilds hair bonds at a molecular level.

Clinical notes (as part of the Olaplex system)

• When used as part of a three-part system (No. 0, No. 3, No. 4) in just one use, improvements include up to 68% more repair, easier detangling, and smoother hair.
• In the same system, a 65% reduction in breakage has been observed, along with improved conditioning.

Usage tips

Apply to dry hair, from roots to ends, then proceed with No. 3 Hair Perfector. Leave No. 0 on for 10 minutes, then rinse and continue with your treatment routine. The nozzle design supports fast, efficient pre-treatment before styling or finishing steps.

Who should consider it

Ideal for all hair types—coily, curly, straight, and wavy—seeking a proactive step to help your at-home bond-building routine feel targeted and precise. If you want a salon-inspired pre-treatment that complements your No. 3 regimen, this is worth considering.
