Olaplex N°.0 Intensive Bond Building Hair Treatment, 155 mL — Priming Repair for Stronger, Manageable Hair

Olaplex N°.0 Intensive Bond Building Hair Treatment is a targeted primer designed to jump-start structural repair before you follow with Olaplex No.3 Hair Perfector (sold separately). Delivered through a precision nozzle for a stream application, N°.0 prepares the hair shaft so the No.3 step can work more effectively, helping to rebuild bonds and improve manageability across coily, curly, wavy, and straight textures.

How does N°.0 prepare hair for deeper repair?

N°.0 is formulated to penetrate and prime each strand so repairing agents in the follow-up treatment can access internal bonds more efficiently. Applied as the first step in a two-part routine, its concentrated formula creates a receptive environment for the No.3 Hair Perfector to act on weakened areas.

• Precision nozzle delivers a focused stream to coat hair from root to tip
• Concentrated primer penetrates the strand to improve product uptake
• Designed specifically to be followed by No.3 for amplified repair

Will N°.0 work on all hair types and damage levels?

Yes — N°.0 is formulated for use on coily, curly, wavy, and straight hair, and can be used on a range of damage from light breakage to chemically or mechanically stressed strands. It is intended to support bond rebuilding and strength regardless of texture, when used as directed with No.3.

• Suitable for chemically treated, heat-styled, and naturally textured hair
• Works on varying damage intensities when used in a two-step routine
• Professional-inspired formula used in salons and at home

How do I use N°.0 with No.3 for best results?

Apply N°.0 to dry hair as the first step, using the nozzle to target the mid-lengths and ends, then follow immediately with No.3 Hair Perfector. Leave both products on for the recommended time to allow bond rebuilding activity, then rinse and proceed with your usual shampoo and conditioner.

• Start on dry hair; apply N°.0 evenly with the applicator nozzle
• Follow immediately with No.3 (sold separately) for enhanced repair
• Allow recommended processing time before rinsing and styling

What results can I expect after using N°.0?

When used in tandem with No.3, N°.0 helps improve hair strength and resilience, leading to less breakage and improved manageability over time. Results will vary with hair condition and consistency of use, but many users notice smoother texture and easier detangling after regular treatments.

• Improved manageability and smoother texture with repeated use
• Reduced visible breakage when incorporated into a two-step routine
• Supports long-term integrity when used as directed

Who is this for: Olaplex N°.0 is intended for anyone seeking a salon-inspired at-home step to prep and strengthen damaged or stressed hair. It’s especially useful for people who color, heat-style, chemically process, or frequently manipulate their hair and who want a targeted primer to amplify the effects of the No.3 Hair Perfector. Ideal for all hair textures and those committed to a short at-home repair routine.
