Olaplex N°.0 Intensive Bond Building Hair Treatment 155 mL — Concentrated Primer for Strength & Repair

This professional-inspired 155 mL treatment is formulated to jump-start internal repair and protect hair integrity across coily, curly, wavy, and straight textures. Designed as the first step in a two-part system when paired with Olaplex No.3 Hair Perfector (sold separately), N°.0 uses a precise nozzle for a targeted stream application so the formula saturates strands and primes them to receive maximum restorative benefits.

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

N°.0 lays the groundwork by penetrating the hair shaft and addressing weakened bonds, creating optimal conditions for No.3 to work more effectively. It’s intended to be used immediately before No.3 to amplify repair results.

• Concentrated formula targets internal bond repair
• Stream nozzle lets you apply product at the roots and along the strand
• Prepares hair to absorb the follow-up treatment more thoroughly

What results can I expect after using N°.0 with No.3?

When used as directed—N°.0 followed by No.3—you should notice improved strength, reduced breakage, and smoother texture. Results depend on hair condition and frequency of use, with best effects seen after multiple treatments.

• Increased strand resilience against breakage
• Smoother, more manageable surface texture
• Noticeable improvement after repeated two-step sessions

How do I use N°.0 in my at-home routine?

Apply to dry hair, working the stream nozzle to saturate each section. Leave on for the recommended time, then apply No.3 Hair Perfector (sold separately) on top; rinse and follow with your regular shampoo and conditioner routine.

• Use on dry, detangled hair for best absorption
• Apply throughout lengths and ends, not just roots
• Follow immediately with No.3 for a two-step intensive repair

Is N°.0 suitable for my hair type?

N°.0 is formulated for all hair textures—coily, curly, wavy, and straight—and addresses damage from coloring, heat styling, chemical services, and everyday wear. It acts as a universal primer to strengthen and protect strands before deeper repair.

• Safe for color-treated and chemically processed hair
• Works on thin to thick and fine to coarse strands
• Ideal when combined with No.3 for targeted repair

Who is this for: Olaplex N°.0 is aimed at anyone experiencing hair damage, fragility, or rough texture who wants a salon-grade primer for at-home repair. It’s especially useful for people who regularly color or heat-style their hair and those looking to boost the performance of Olaplex No.3 Hair Perfector as part of an at-home restorative regimen.
