Olaplex – No.0 Bond Builder 155ml

Olaplex No.0 Intensive Bond Building Treatment (155ml): The At-Home Professional Repair Booster

The Olaplex No.0 Intensive Bond Building Treatment is a highly potent, restorative hair primer designed to maximize the efficacy of the best-selling No.3 Hair Perfector. Packaged in a 155ml bottle with an easy-to-use nozzle for precise application, the No.0 is inspired by the first step of the professional in-salon Olaplex treatment, bringing the deep, transformative power of bond-building home.

This treatment contains the highest concentration of the patented OLAPLEX Bond Building Technology™ (Bis-Aminopropyl Diglycol Dimaleate) in any at-home Olaplex liquid product. It acts as a primer, saturating the hair to ensure maximum absorption of the No.3 Hair Perfector that is layered on top. This two-step system (No.0 followed by No.3) is clinically proven to deliver the most intensive at-home repair possible.

Scientifically Proven Deep Repair:

The No.0 is specifically designed to target and rebuild the shattered disulfide bonds within the hair structure, which are weakened by thermal, mechanical, and chemical damage. When used as a two-part system with the No.3, the results are dramatic:

• 68% More Repair
• 3 times Stronger Hair
• Significantly improved conditioning, smoothness, and detangling.

This powerful liquid is essential for all hair types, particularly those with visible and severe damage, dryness, and brittleness. It is the core treatment to restore the hair’s healthy appearance, strength, and shine.

How to Use the Two-Part System:

The No.0 is not intended for use alone; it is the crucial first step in a powerful repair system:

1. Prime: Apply No.0 slowly to dry hair, distributing evenly from root to tip in small sections. Saturate the hair until it is damp, not drenched. Leave on for 10 minutes.
2. Intensify: Do not rinse the No.0. Layer a generous amount of No.3 Hair Perfector directly over the No.0. Comb through to ensure full saturation. Leave on for an additional 10 minutes (for a total minimum treatment time of 20 minutes).
3. Cleanse & Condition: Rinse thoroughly, then shampoo and condition with Olaplex No.4 and No.5.

Use this system once a week, or 2-3 times per week for very damaged hair. The formula is color-safe, vegan, cruelty-free, and free from sulfates, parabens, and gluten, ensuring the cleanest and most potent repair treatment available for home use.
