Olaplex N°.5FINE Volumizing Bond Maintenance Conditioner — 1000 mL Concentrated Repair & Root Lift for Fine Hair

This concentrated 1000 mL professional-size bottle delivers a gentle yet powerful conditioning step specially designed for fine hair textures. It combines Olaplex’s patented bond-building technology with low molecular weight hyaluronic acid and flexible polymers to rebuild weakened disulfide bonds, hydrate without weighing hair down, and create long-lasting volume from the roots. Suitable for straight, wavy, curly, or coily fine hair and safe for color-treated or chemically processed strands, N°.5FINE targets everyday damage while preserving lightness and bounce.

How does this conditioner add volume without making fine hair heavy?

The formula uses lightweight polymers that lift at the root and a hydra-balancing matrix that conditions mid-lengths and ends without excess weight. Rather than coating hair with heavy oils, it deposits structure-building ingredients where needed to maintain movement and body all day.

• Flexible polymers create immediate root lift and fuller-looking hair.
• Hydra-balancing matrix provides hydration while preventing limpness.
• Low molecular weight hyaluronic acid moisturizes without heaviness.
• Concentrated formula means small amounts cover more surface area.

Will it repair damage and make hair stronger in one use?

N°.5FINE is formulated to begin repairing visible wear caused by styling and environmental stress after a single application thanks to Olaplex’s bond-building ingredient. While one use improves manageability and smoothness, continual use as part of the Nº.4FINE shampoo system increases measurable strength and reduces breakage over time.

• Patented bond-building technology helps rebuild disulfide bonds.
• Clinically tested benefits include reduced breakage and improved strength when used as a system.
• Instant detangling and smoother cuticle appearance after one wash.
• Designed for daily wear and chemically treated hair.

How should I use the 1000 mL supply to get the best results?

Use after cleansing with Nº.4FINE Bond Maintenance Shampoo on clean, wet hair. Apply a small amount from mid-lengths to ends, leave for 1–3 minutes, then rinse. Because the formula is concentrated, the 1000 mL size stretches farther—ideal for salons or home users who prefer a large refill.

• Apply to wet hair after shampooing, focusing on mid-lengths and ends.
• Leave on 1–3 minutes for optimum absorption, then rinse thoroughly.
• Small application sizes = up to ~100 uses from the 1000 mL bottle.
• Best results when paired with Nº.4FINE shampoo as a system.

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

Yes—N°.5FINE is color-safe and formulated to support chemically treated strands while addressing the specific needs of fine textures. It’s dermatologist tested and vegan, offering protection and hydration that won’t compromise color or chemical services.

• Color-safe formulation preserves salon color vibrancy.
• Suitable for straight, wavy, curly, or coily fine hair types.
• Vegan and dermatologist tested for gentle performance.
• Helps defend against future breakage when used regularly.

Who is this for: Olaplex N°.5FINE Bond Maintenance Volumizing Conditioner in the 1000 mL size is ideal for people with fine hair who want stronger, more voluminous-looking strands without heavy conditioners. It suits salon professionals, households seeking a long-lasting refill, and anyone with fine, color-treated, or chemically processed hair wanting improved detangling, root lift, and lightweight hydration.
