Olaplex Nº.5 Bond Maintenance Conditioner 250 mL — Strengthens Hair, Reduces Breakage & Frizz

Olaplex Nº.5 Bond Maintenance™ Conditioner is a concentrated, bond-building conditioner that strengthens hair, reduces breakage, and improves shine and manageability with every wash.

Backed by Olaplex's patented bond-building chemistry, Nº.5 is a moisturizing, color-safe conditioner formulated to restore internal hair strength while smoothing and detangling strands. Its concentrated formula is sulfate-, paraben- and phthalate-free and designed for all hair types — from coily and curly to straight and wavy. Use it after the matching Olaplex shampoo for best results; a little product goes a long way, making the 250 mL size ideal for regular home use.

How does Nº.5 help reduce breakage and improve strength?

Nº.5 contains Olaplex's active bis-aminopropyl diglycol dimaleate ingredient that works at the hair bond level to reinforce structural integrity. In combination with moisturizing agents like panthenol and glycerin, the conditioner supports elasticity and reduces the chance of breakage during styling and brushing.

• Reinforces internal bonds to increase resilience
• Panthenol and glycerin attract and retain moisture
• Formulated to support stronger hair when used as part of the Olaplex system

Will this conditioner work on color-treated or chemically processed hair?

Yes — Nº.5 is color-safe and suitable for chemically treated hair. Its sulfate-free and paraben-free formulation helps protect color while repairing mechanical and chemical damage without stripping pigment or moisture.

• Safe for use after coloring, bleaching, or perms
• Helps preserve color while improving texture and shine
• Designed for sensitive salon-treated strands

How should I use Olaplex Nº.5 for best results?

After shampooing with Olaplex Nº.4 or your preferred cleanser, dispense a small amount and apply from mid-lengths to ends. Leave on for 1–3 minutes for quick conditioning, or longer if extra detangling and slip are needed, then rinse thoroughly.

• A little goes a long way—average 5 mL per application
• 250 mL typically provides around 50 applications
• Use regularly as part of the Nº.4 + Nº.5 system for maximum benefit

What tangible benefits can I expect after using Nº.5?

Nº.5 is formulated to provide smoother, shinier, and more manageable hair while helping decrease frizz and ease detangling. Clinical testing reported improvements in shine, hydration, and reduced friction, especially when used alongside Olaplex shampoo.

• Improves detangling and reduces styling time
• Leaves hair feeling softer and appearing glossier
• Helps reduce frizz and increases manageability in one wash

Who is this for: Olaplex Nº.5 is designed for anyone seeking stronger, more manageable hair — including people with coarse, curly, chemically treated, color-treated, or fine hair. It suits daily or weekly routines and is ideal for those who want a concentrated conditioner that repairs, hydrates, and defends against future breakage without weighing hair down.
