Olaplex Nº.5 Bond Maintenance Conditioner 525 mL — Strengthening, Frizz-Reducing Formula for Medium to Coarse Hair

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

Designed for medium to coarse hair textures but effective across coily, curly, straight, and wavy hair, this 525 mL formula delivers intense hydration, easier detangling, and noticeable frizz control while defending against future breakage. It works as part of the Olaplex bond-maintenance system to replenish moisture, restore resilience, and improve manageability without weighing hair down.

How quickly will I see repair and less breakage?

Many users notice softer, smoother hair after the first use and measurable bond reinforcement when used consistently with the Nº.4 shampoo. The concentrated formula targets damaged areas to reduce mechanical and chemical breakage over time.

• Repairs everyday damage in one wash when paired with Nº.4
• Clinically shown to reduce breakage and strengthen hair at a molecular level
• Delivers weightless hydration to prevent future snapping

Will this conditioner work on chemically treated or color hair?

Yes — Olaplex Nº.5 is color-safe and suitable for chemically treated hair. Its bond-reinforcing technology is formulated to protect and restore strands that have been lightened, colored, straightened, or heat-styled.

• Safe for color-treated and processed hair
• Maintains vibrancy while improving texture and gloss
• Helps prevent length loss caused by bleaching or chemical services

How much should I use and what’s the best way to apply it?

This is a concentrated conditioner, so a little goes a long way — roughly 5 mL per application on average. Apply after shampooing to mid-lengths and ends, leave for 1–3 minutes, then rinse thoroughly for optimum results.

• Dispense a small amount, focusing on mid-lengths and ends
• Leave in 1–3 minutes to allow bond-repairing ingredients to work
• Rinse well; for best results use with Nº.4 Bond Maintenance Shampoo

What tangible benefits will I notice in daily styling?

Expect improved detangling, reduced frizz, and increased manageability that simplifies styling routines. The formulation enhances softness and shine, making hair easier to comb, dry, and style with less risk of breakage from brushing or heat tools.

• Clinically proven to give smoother, more manageable hair in one wash
• Improves detangling by up to 90% when used as a system
• Reduces frizz and boosts shine for cleaner styling results

Who is this for? Olaplex Nº.5 Bond Maintenance Conditioner is ideal for anyone with medium to coarse hair seeking stronger, more resilient strands — including those with curly, coily, wavy, or straight hair, and people with color-treated or chemically processed hair. It’s especially useful for anyone struggling with breakage, tangles, or persistent frizz who wants a concentrated, salon-grade conditioner to support daily strength and shine.
