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

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

This lightweight yet highly concentrated conditioner is formulated for medium to coarse hair textures and designed to work with the Olaplex bond-building system. It nourishes and detangles while replenishing hydration and boosting shine without weighing hair down. Safe for color-treated and chemically processed hair, the formula targets brittleness and frizz to improve manageability after one use.

How quickly will I see stronger, less damaged hair?

Many users notice improved manageability and smoother strands after the first rinse, thanks to bond-reinforcing actives and humectants that hydrate and cushion hair fibers. Clinical testing in system use shows meaningful reductions in breakage and measurable increases in strength at a molecular level.

• Works in one wash when paired with Olaplex Nº.4 shampoo
• Contains panthenol and glycerin to draw and retain moisture
• Formulation designed to rebuild and reinforce weakened bonds

Will this conditioner help with frizz and shine?

The conditioner smooths cuticles and increases surface reflectivity to visibly reduce frizz and enhance shine. Its lightweight conditioning agents hydrate without creating heavy residue, so hair looks polished but still bouncy.

• Clinically shown to reduce frizz and boost shine
• Weightless hydration promotes a soft, smooth finish
• Color-safe ingredients preserve salon treatments

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

After shampooing with Nº.4 Bond Maintenance Shampoo, apply a small amount of Nº.5 from mid-lengths to ends, leave on for 1–3 minutes, then rinse. Because the formula is concentrated, a little goes a long way—standard 100 mL sizing can deliver many applications.

• Apply after shampooing to damp hair, focusing on damaged areas
• Leave for 1–3 minutes before rinsing thoroughly
• Use regularly as part of the Olaplex system for best protection

Is this product safe for chemically treated or colored hair?

Yes—this conditioner is formulated to be color-safe and suitable for chemically processed hair. It is dermatologist-tested and vegan, designed to maintain color vibrancy while addressing structural damage and breakage.

• Vegan and dermatologist-tested formulation
• Safe for color-treated and chemically processed hair
• Helps protect length and fullness by reducing breakage

Who is this for: Olaplex Nº.5 Bond Maintenance Conditioner is aimed at anyone with medium to coarse hair textures seeking to repair everyday damage, cut down on breakage, and improve detangling and manageability.
