Olaplex Nº.5 Bond Maintenance Conditioner 1000 mL — Strengthening, Frizz-Reducing for Medium to Coarse & Color-Treated Hair

Olaplex Nº.5 Bond Maintenance™ Conditioner is a concentrated strengthening conditioner that repairs everyday damage, reduces frizz, and improves detangling in a single wash.

This professional-strength, 1000 mL conditioner is formulated for medium to coarse hair textures and works by reinforcing weakened bonds to make hair more resilient, hydrated, and manageable. It complements Olaplex’s bond-repairing system and is safe for color-treated and chemically processed hair. The rich formula uses Panthenol and Glycerin to attract and retain moisture while delivering clinically tested improvements in strength, shine, and ease of styling.

How does this conditioner repair damage and strengthen hair?

Nº.5 targets everyday mechanical and environmental damage by reinforcing internal hair bonds to reduce breakage and improve structure. Results are measurable when used with the Olaplex system, showing stronger hair at a molecular level and less breakage over time.

• Rebuilds and reinforces bonds for improved resilience
• Clinically shown to deliver 2X stronger hair at a molecular level
• Reduces breakage up to 60% when used as part of the system

Will it help with frizz, shine, and manageability?

The conditioner smooths hair cuticles and boosts hydration for visible shine and reduced frizz after one application. You’ll notice easier detangling and softer texture that makes styling faster and more predictable.

• Clinically proven to reduce frizz and increase shine
• Improves detangling by up to 90% for less tugging
• Provides weightless hydration for soft, manageable strands

How should I use the 1000 mL size for best results?

After shampooing with Nº.4 Bond Maintenance Shampoo, apply a small amount from mid-lengths to ends, leave on for 1–3 minutes, then rinse thoroughly. Because the formula is highly concentrated, a little goes a long way — the 1000 mL bottle supplies many applications for long-term use.

• Recommended application: 5 mL on average per use
• 1000 mL yields up to ~100 applications at average use
• Use as part of the Olaplex system for clinical benefits

Is this conditioner safe for colored and chemically treated hair?

Yes — Nº.5 is color-safe, vegan, and dermatologist-tested, designed to work on chemically treated hair without stripping color. Its formulation replenishes moisture and helps protect fragile strands that have been lightened, relaxed, or otherwise processed.

• Suitable for color-treated and chemically processed hair
• Vegan and dermatologist-tested for gentle use
• Formulated to maintain softness and vibrancy

Who this is for: Olaplex Nº.5 is aimed at anyone with medium to coarse hair seeking to repair daily wear and strengthen strands—especially people with frizz, tangles, or chemically treated hair who want long-lasting hydration and improved manageability. The 1000 mL professional size is ideal for households, salons, or users who prefer value and fewer refills while maintaining the Olaplex bond repair routine.
