Olaplex Nº.5 Bond Maintenance Conditioner 100 mL — Strengthening, Frizz-Reducing Repair for Medium-to-Coarse Hair

Olaplex Nº.5 Bond Maintenance™ Conditioner is a concentrated repairing conditioner that restores strength, reduces frizz, and improves detangling in one rinse for medium-to-coarse hair.

This rich conditioner from Olaplex targets weakened areas of the hair with bond-building technology while delivering hydration and slip for easier comb-through. Formulated to be color-safe, vegan, and dermatologist tested, Nº.5 works after cleansing to seal moisture, enhance shine, and protect against everyday mechanical damage and breakage without weighing hair down.

How quickly will I see reduced breakage and stronger hair?

Visible improvements appear after one wash when used as part of the Olaplex Bond Maintenance system. The patented bond-reinforcing ingredient helps rebuild structural weakness, while panthenol and glycerin hydrate and fortify strands to resist split ends and snapping during styling.

• Repairs everyday damage in one use when combined with the matching shampoo.
• Clinically shown to increase molecular strength and lower breakage.
• Helps hair retain length and fullness over repeated use.

Will this conditioner work for my hair type and color-treated hair?

Nº.5 is formulated for medium to coarse textures and is compatible with color-treated and chemically processed hair. Its weightless conditioning system adds moisture and slip without stripping color or leaving a heavy residue, making it suitable for coily, curly, wavy, and straight patterns that need reinforcement.

• Color-safe and dermatologist tested for use on treated hair.
• Designed to perform on textured, frizzy, or chemically altered strands.
• Recommended for anyone seeking stronger, more manageable hair.

How should I use Nº.5 for best results?

After shampooing with Olaplex Nº.4 Bond Maintenance Shampoo, apply a small amount of Nº.5 to mid-lengths and ends. Leave it on for 1–3 minutes before rinsing; the concentrated formula means a little goes a long way—about 5 mL per application on average.

• Use with Nº.4 for optimal repair and clinical benefits.
• 100 mL bottle yields up to ~25 applications based on average use.
• Rinse thoroughly and style as usual; repeat at each wash.

What measurable benefits can I expect from regular use?

Clinical testing with the Olaplex system demonstrates significant gains in manageability, hydration, and shine while reducing frizz and breakage. Regular use helps hair feel softer, detangle more easily, and appear fuller and healthier over time.

• Clinically shown to boost shine and reduce frizz.
• Up to 90% easier detangling and 90% more weightless hydration in tests.
• Results strengthen and protect hair structure with continued use.

Who is this for: Olaplex Nº.5 Bond Maintenance Conditioner is ideal for people with medium-to-coarse hair seeking to repair daily wear and tear, smooth frizz, and improve manageability—especially those with color-treated or chemically processed hair.
