Hair strengthening treatment Olaplex No. 0 Intensive Bond Builder, 155 ml

Olaplex No. 0 Intensive Bond Builder, 155 ml is a salon-grade preparatory treatment formulated to rebuild and reinforce the internal bonds of damaged, chemically treated and weakened hair. Supplied in a 155 ml bottle, this concentrated primer delivers the highest take-home dose of patented Olaplex technology to prime hair for deeper repair when used before an at-home or in-salon follow-up treatment. It is intended to improve strength, manageability and resilience while preparing hair to absorb the active ingredients of the next step in a two-part routine.

Advantages

This intensive bond builder delivers a concentrated dose of bond-repairing technology to restore structural integrity and reduce breakage. It is designed to work as the first step in a two-part system to maximise repair, increasing hair strength and improving texture without the use of list-style application complexity. The formula is suitable for repeated use as part of a restorative regimen and is compatible with colour-treated hair.

Suitable for

• Damaged or chemically treated hair (bleached, coloured, relaxed)
• Weak, brittle or porous hair that needs strengthening
• Preparatory step before intensive in-salon or at-home treatments
• Users seeking improved manageability and reduced breakage

Key specifications

• Format: concentrated liquid treatment in a 155 ml bottle
• Function: bond rebuilding and hair strengthening
• Primary effects: improved tensile strength, reduced breakage, enhanced manageability
• Compatibility: suitable for colour-treated and chemically processed hair
• Usage system: designed as step one in a two-step repair routine

How to use

Apply evenly to dry hair, working from roots to ends to fully saturate strands. Leave on for the recommended processing time to allow the active bond-building ingredients to penetrate the hair structure, then follow with the designated follow-up treatment as directed for optimal repair results. Typical use frequency depends on hair condition; a single bottle generally provides multiple applications depending on hair length and density.

Usage recommendations

For best results, use Olaplex No. 0 as the preparatory step immediately before the follow-up bond perfector. Adjust application amount according to hair length and density; shorter or finer hair requires less product while longer or denser hair requires more. Follow the time and pairing instructions exactly to maximise repair and strengthen hair fibers.
