Olaplex Nº.5FINE Lightweight Volumizing Conditioner 100 mL — Bond-Repairing, Weightless Volume for Fine Hair

Olaplex Nº.5FINE Bond Maintenance™ Lightweight Volumizing Conditioner is a weightless, bond-repairing conditioner that instantly adds body, detangles, and defends fine hair from everyday breakage.

This concentrated 100 mL conditioner is formulated for fine textures—whether straight, wavy, curly, or coily—and works with Olaplex bond-building technology to strengthen hair while delivering lift at the roots without heaviness. In one rinse it restores moisture, smooths strands, and improves manageability, making styling easier and helping protect hair length and fullness over time.

How does Nº.5FINE add volume without weighing hair down?

Nº.5FINE combines lightweight polymers with a hydra-balancing matrix so hair gets lift at the root and soft, airy body through the lengths. The formula is concentrated, so a small amount spreads easily and avoids buildup.

• Flexible polymers create immediate root lift and all-day volume.
• Low molecular weight hyaluronic acid hydrates without heaviness.
• Hydra-Balancing Matrix prevents over-conditioning common in fine hair.
• Concentrated formula means fewer product applications and less residue.

Will this conditioner repair damage and reduce breakage?

Yes—Olaplex’s patented bond-building technology works on a molecular level to rebuild and strengthen disulfide bonds, which helps repair routine damage and reduces future breakage when used regularly. Clinical testing shows measurable improvements after just one wash when paired with the matching shampoo.

• Patented bond-building ingredients strengthen hair internally.
• Clinically shown to reduce breakage and improve molecular strength.
• Repairs everyday wear from brushing, styling, and environmental stressors.
• Best results when used as part of the Nº.4FINE + Nº.5FINE system.

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

Apply a small amount to clean, wet hair from mid-lengths to ends after shampooing. Leave the conditioner on for 1–3 minutes, then rinse thoroughly—no heavy leave-in step necessary. Because the formula is concentrated, a little goes a long way.

• Use after Nº.4FINE Bond Maintenance Shampoo for optimal benefits.
• Apply 5 mL on average per use—100 mL can deliver up to 25 applications.
• Leave on 1–3 minutes then rinse; safe for color-treated and chemically processed hair.
• Suitable for all porosity levels and hair patterns from straight to coily.

Is this product safe for colored or chemically treated fine hair?

Nº.5FINE is color-safe, dermatologist tested, and vegan, so it’s formulated to support chemically treated hair while helping preserve color and integrity. The lightweight hydration helps protect treated strands without flattening them.

• Color-safe formulation that won’t strip dye.
• Dermatologist tested for gentler performance on sensitive scalps.
• Vegan and free of ingredients that typically weigh down fine hair.
• Works across straight, wavy, curly, and coily textures.

Who is this for? If you have fine hair and want more body, easier detangling, and scientifically backed repair without adding weight, Nº.5FINE is designed for you. It’s ideal for anyone seeking daily strength and lift—those with natural or styled fine textures, color-treated strands, and people who prioritize lightweight hydration and damage defense in their haircare routine.
