Olaplex N°.0 Intensive Bond Building Hair Treatment 155 mL — Primer for No.3, Strengthens & Reduces Breakage

Olaplex N°.0 is a salon-grade, at-home primer treatment that jump-starts bond repair and strengthens hair when used before No.3 Hair Perfector.

Olaplex N°.0 Intensive Bond Building Hair Treatment is formulated to prepare the hair for deeper reconstruction and protection. Designed with a precision nozzle for a targeted stream application, this 155 mL bottle delivers a concentrated liquid that penetrates the hair shaft to prime strands for the follow-up No.3 treatment (sold separately). The system is meant to work across coily, curly, wavy, and straight hair textures to boost overall resilience and improve manageability after styling and chemical services.

How does N°.0 prepare hair for the No.3 treatment?

N°.0 acts as the first step in a two-part repair system by delivering an intense, concentrated formula that opens the way for deeper repair from No.3. It lays down active ingredients that allow the following hair perfector to work more efficiently inside the strand.

• Targets strands with a thin, streamable formula for even coverage
• Primes the hair structure to accept No.3's concentrated reparative ingredients
• Used immediately before No.3 for best results

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

When used as directed—N°.0 followed by No.3—you can expect hair that feels stronger and appears more resilient. Improvements will vary by hair condition, but most users report better detangling, reduced breakage during styling, and enhanced manageability.

• Noticeable improvement in comb-through ease and softness
• Helps reduce breakage from mechanical stress like brushing and styling
• Supports smoother, more uniform texture after treatment

How do I use N°.0 correctly for best performance?

Apply N°.0 to dry hair from roots to ends using the precise nozzle, saturating each section so the concentrated formula reaches the strand core. Leave it on for the recommended time, then apply No.3 over top; follow with rinsing and regular shampooing if directed on the bottle.

• Work on dry hair and saturate strands thoroughly
• Apply No.3 directly after N°.0 for at-home two-step repair
• Follow Olaplex directions for timing and rinsing

Will N°.0 work on color-treated, heat-damaged, or textured hair?

N°.0 is formulated for all hair types and can be used on color-treated, heat-stressed, chemically processed, or naturally textured hair. It doesn’t change color but supports strand integrity to help hair better withstand future styling and chemical services.

• Safe for color-treated and chemically processed hair when used as directed
• Useful for heat-damaged hair to improve strength and manageability
• Suitable for straight, wavy, curly, and coily textures

Who is this for? Olaplex N°.0 is ideal for anyone looking to fortify compromised hair before at-home repair—especially those with visible breakage, weakened strands from coloring or heat tools, or anyone wanting a professional-style primer to boost the effectiveness of No.3 Hair Perfector. If you’re maintaining salon-treated hair, frequently use hot tools, or need targeted bond support, N°.0 provides a concentrated first step to a stronger, more resilient finish.
