Olaplex N°.5 Bond Maintenance Strengthening Conditioner — 1000 mL, bond‑repairing, color‑safe hydration

Olaplex N°.5 Bond Maintenance™ Strengthening Conditioner is a concentrated, bond-repairing conditioner that restores strength, smoothness, and manageability to medium‑coarse hair in a single rinse.

Designed as part of the Olaplex bond‑maintenance system, Nº.5 is a rich conditioner formulated to target everyday damage from styling, heat, and chemical processes. It rebuilds weakened bonds, adds weightless hydration, reduces frizz, and makes detangling faster, while remaining color‑safe and vegan. The 1000 mL size is ideal for salons, frequent users, or anyone who prefers to stock up on a professional‑grade conditioner that lasts.

How will this conditioner improve my hair’s strength and reduce breakage?

Nº.5 contains Olaplex’s bond‑repairing technology plus humectants like panthenol and glycerin to reinforce hair structure while attracting moisture. Together they help hair resist breakage during brushing and styling.

• Rebuilds and reinforces internal bonds for greater resilience.
• Panthenol and glycerin provide hydration that prevents brittleness.
• Clinically shown to reduce breakage when used in the system.

Will it make my hair easier to detangle and style?

This concentrated formula smooths the cuticle and increases slip, so knots come out with less pulling and styling becomes simpler. You’ll notice improved manageability immediately after one application.

• Dramatically improves detangling for faster, gentler comb‑throughs.
• Creates a smoother surface for heat tools and styling products.
• Leaves hair soft without weighed‑down residue.

Is this safe for color‑treated or chemically processed hair?

Yes — Nº.5 is color‑safe and suitable for chemically treated hair. It focuses on repairing and protecting hair integrity while preserving salon color and treating previously processed strands gently.

• Formulated to maintain color vibrancy while repairing bonds.
• Vegan and dermatologist‑tested for broad compatibility.
• Developed to be used alongside Olaplex №.4 shampoo for best results.

How should I use the 1000 mL bottle and how long does it last?

The formula is highly concentrated, so a little goes a long way. After shampooing, apply a small amount to mid‑lengths and ends, leave for 1–3 minutes, then rinse thoroughly. The large 1000 mL size is tailored for frequent use or salon environments.

• Recommended application: 5 mL per use on average.
• 1000 mL provides roughly 100 applications at average use.
• Works best when paired with Nº.4 Bond Maintenance Shampoo and other Olaplex system products.

Who this is for: Olaplex N°.5 Bond Maintenance™ Strengthening Conditioner is aimed at people with medium to coarse hair who want to repair everyday damage, minimize breakage, and simplify detangling without sacrificing shine or color. It’s also a practical choice for stylists, salons, and heavy users who need a concentrated, professional‑grade conditioner in a large, cost‑effective size.
