Olaplex Nº.5 Bond Maintenance Conditioner 1000 mL — Strengthening, Frizz‑Reducing Repair for Color‑Treated Hair

Olaplex Nº.5 Bond Maintenance™ Conditioner is a concentrated strengthening conditioner that repairs everyday damage, reinforces hair bonds, and smooths frizz in a single wash.

Designed for medium to coarse hair textures but suitable for all types, this high-capacity 1000 mL conditioner delivers targeted hydration, easier detangling, and improved manageability without weighing hair down. Its bond-building formula works with Olaplex science to restore resilience while replenishing moisture and softness. Clinically tested and safe for color- and chemically treated hair, Nº.5 helps protect hair length and fullness when used as part of the Olaplex system.

How does Nº.5 repair and strengthen hair in one wash?

The conditioner contains Olaplex’s bond-reinforcing actives plus humectants like panthenol and glycerin to rebuild and hydrate the hair fiber. Within a single application it helps reduce breakage and improves tensile strength at a molecular level.

• Reinforces internal bonds for stronger hair fibers
• Panthenol and glycerin attract and lock in moisture
• Clinically shown to reduce breakage and boost strength

Will it smooth frizz and make detangling easier?

Yes—Nº.5 smooths the cuticle and adds slip for faster, gentler detangling, which reduces stress on strands. The formula helps control frizz and increases manageability immediately after rinsing.

• Dramatically improves detangling — up to 90% easier when used in-system
• Reduces frizz and enhances shine for a sleeker finish
• Leaves hair softer and more manageable in one use

How concentrated is the 1000 mL size and how should I use it?

The 1000 mL refill-sized bottle is highly concentrated so a small amount goes a long way. Apply after shampooing to mid-lengths and ends, leave for 1–3 minutes, then rinse thoroughly for best results.

• 1000 mL yields roughly 100 applications based on a 5 mL serving
• Dispense and apply to damp hair after Nº.4 Bond Maintenance Shampoo
• Leave on 1–3 minutes for optimal conditioning, then rinse

Is this product safe for colored or chemically treated hair?

Nº.5 is color-safe and formulated to be compatible with chemically treated hair. It’s dermatologist tested and vegan, designed to protect treated hair while helping maintain color integrity and manageability.

• Color-safe and suitable for chemically treated hair
• Dermatologist tested and vegan-friendly formulation
• Helps defend against future breakage to preserve hair length and fullness

Who is this for: Olaplex Nº.5 Bond Maintenance Conditioner is ideal for anyone wanting to repair everyday damage and strengthen hair—from coily and curly to straight and wavy textures—especially people with medium to coarse hair or those who regularly color or chemically treat their hair. It’s also a strong choice for households and salons seeking a concentrated, high-volume refill that delivers visible smoothing, improved detangling, and reinforced bonds with regular use.
