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

Olaplex Nº.5 Bond Maintenance™ Conditioner is a concentrated, bond-building conditioner that strengthens hair, reduces breakage, and leaves strands smoother, shinier, and more manageable after every wash.

This sulfate-, paraben- and phthalate-free conditioner uses Olaplex’s patented bond-building technology to restore internal strength and moisture to all hair types. Formulated to work on chemically treated, heat-styled, curly, wavy, coily, and straight hair, Nº.5 replenishes hydration, improves detangling, and helps defend against future damage while remaining color-safe and vegan.

How quickly will I notice reduced breakage and improved manageability?

Many users report visible improvement after a single use, especially when paired with Olaplex Nº.4 shampoo. The formula targets compromised bonds within the hair shaft to increase resilience and reduce snapping during styling and brushing.

• Clinically shown to repair everyday damage in one wash
• Improves detangling—up to 90% easier when used as directed
• Leaves hair smoother and more manageable immediately
• Recommended to apply to mid-lengths and ends for best results

What are the key ingredients and how do they benefit my hair?

Nº.5 combines Olaplex’s signature bond-building molecule with moisturizing and strengthening agents that work together to hydrate and protect. Humectants, oils, and conditioning polymers help restore softness without weighing hair down.

• Bis-Aminopropyl Diglycol Dimaleate — Olaplex’s bond-builder for structural repair
• Panthenol and glycerin — attract and retain moisture to reduce brittleness
• Avocado, grape seed and other botanical oils — add shine and smooth the cuticle
• Light conditioning silicones and polymers — enhance slip for easier detangling

How should I use Nº.5 for the best results and how concentrated is it?

After cleansing with Nº.4 or your preferred shampoo, apply a small amount of Nº.5 to damp mid-lengths and ends, leave on for 1–3 minutes, then rinse thoroughly. The conditioner is concentrated—only a little is needed, making the 250 mL size long-lasting for regular use.

• Apply to towel-dried hair after shampooing; focus on mid-lengths and ends
• Leave for 1–3 minutes for optimal absorption, then rinse well
• 250 mL typically yields many applications—use roughly 5 mL per wash
• For maximum benefit, use as a system with Nº.4 Bond Maintenance Shampoo

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

Yes — Nº.5 is color-safe and formulated to be gentle on chemically processed hair while helping to rebuild weakened bonds. It’s dermatologist-tested and free from sulfates, parabens, and phthalates, making it compatible with many salon services and home treatments.

• Color-safe and suitable for bleached, dyed, or relaxed hair
• Vegan formulation with no sulfates, parabens, or phthalates
• Dermatologist-tested for broad hair-type compatibility
• Pairs well with Olaplex treatments and professional salon services

Who this is for: Olaplex Nº.5 Bond Maintenance Conditioner is designed for anyone looking to strengthen and hydrate hair—ideal for people with damaged, chemically treated, heat-styled, frizzy, curly, wavy, or straight hair who want improved manageability, reduced breakage, and increased shine. If you want a concentrated, science-backed conditioner that protects and repairs while remaining color-safe and vegan, Nº.5 fits into both daily routines and weekly restorative care.
