Olaplex N°.5 Bond Maintenance Strengthening Conditioner 250 mL — Color‑Safe, Bond‑Building Repair

Olaplex N°.5 Bond Maintenance™ Strengthening Conditioner is a concentrated, color-safe conditioner that rebuilds and hydrates hair bonds to reduce breakage and leave hair smoother, shinier, and more manageable.

Formulated with Olaplex’s patented bond-building chemistry, this moisturizing conditioner targets internal hair strength while restoring softness and shine. It’s designed for all hair types, safe for color-treated and chemically processed hair, and free from sulfates, parabens, and phthalates. A little goes a long way thanks to the concentrated formula — a 250 mL bottle delivers many applications and works best as part of the Olaplex Bond Maintenance system.

How does this conditioner strengthen hair without weighing it down?

N°.5 uses Olaplex’s Bis-Aminopropyl Diglycol Dimaleate to help rebuild broken disulfide bonds inside the hair shaft, while humectants and lightweight emollients restore moisture and smoothness. The result is reinforced strands that remain bouncy and light rather than flattened by heavy oils.

• Bond-building active repairs internal structure.
• Panthenol and glycerin attract and retain moisture.
• Silicone derivatives and esters smooth cuticles for shine without heaviness.

What improvements can I expect after one use and with continued use?

In a single wash many users notice easier detangling, reduced frizz, and improved slip for combing. With regular use as part of the Nº.4/ Nº.5 system, Olaplex reports clinically measured improvement in breakage reduction and long-term strength at a molecular level.

• Instant: better manageability, softer texture, and increased shine.
• Ongoing: less breakage, fuller-looking hair, and improved resilience.
• Clinically tested when paired with Olaplex Bond Maintenance shampoo.

Is this conditioner suitable for color-treated or chemically processed hair?

Yes — the formula is color-safe and formulated to support chemically treated hair by rebuilding bond integrity and replenishing moisture without stripping color or adding harsh sulfates. It’s also vegan and dermatologist tested.

• Sulfate-, paraben-, and phthalate-free for gentle care.
• Color-safe ingredients protect salon-treated hair tones.
• Recommended for all hair types including chemically treated textures.

How do I use Nº.5 to get the best results?

Use after shampooing with Olaplex Nº.4 Bond Maintenance Shampoo for optimal performance. Apply a small, concentrated amount to mid-lengths and ends, leave on for 1–3 minutes, then rinse thoroughly. Adjust amount by hair length and porosity.

• Dispense a small amount; product is highly concentrated.
• Apply to towel-dried mid-lengths and ends; avoid heavy root application.
• Leave 1–3 minutes for best absorption; rinse well.

Who is this for: Olaplex N°.5 is ideal for anyone seeking to repair everyday damage and strengthen hair from within — from color-treated and heat-styled hair to natural textures needing extra resilience. If you want a concentrated, salon-grade conditioner that improves detangling, reduces breakage risk, and enhances shine without weighing hair down, this product fits into daily or weekly maintenance routines and pairs effectively with other Olaplex Bond Maintenance products.
