Olaplex Nº.5FINE Lightweight Volumizing Conditioner for Fine Hair — 250 mL, Bond-Building & Root Lift

This conditioner is formulated specifically for fine hair textures—straight, wavy, curly, or coily—and combines Olaplex’s patented bond-building technology with lightweight hydrators and flexible polymers to deliver body without weighing hair down. It replenishes moisture, improves manageability and detangling, and defends against future breakage while providing instant volume that lasts through the day. Dermatologist tested, vegan, and color-safe, Nº.5FINE pairs best with Nº.4FINE shampoo for a complete system.

How does this conditioner create volume without heaviness?

Nº.5FINE uses flexible polymers to lift and hold hair at the root while a hydra-balancing matrix supplies moisture below the surface so strands stay light and bouncy. The formulation is concentrated so a small amount gives noticeable body without coating the hair.

• Flexible polymers add lift and root support.
• Hydra-balancing matrix hydrates without residue.
• Low molecular weight hyaluronic acid hydrates strands from within.
• Concentrated formula means less product, less buildup.

Will it actually repair damage and reduce breakage?

Olaplex’s patented bond-building technology works at a molecular level to rebuild disulfide bonds that contribute to hair strength. In clinical testing, the system improved hair resilience and reduced breakage when used as directed, helping hair feel stronger and look fuller over time.

• Patented bond-building ingredient restores internal strand strength.
• Clinically shown to reduce breakage and reinforce hair structure.
• Repairs everyday mechanical and environmental damage in one wash.
• Safe for color-treated and chemically processed hair.

How do I use Nº.5FINE to get the best results?

For optimal performance, use after cleansing with Nº.4FINE Bond Maintenance Shampoo. Apply a small amount to clean, wet hair from mid-lengths to ends, leave on 1–3 minutes, then rinse thoroughly. Because the formula is concentrated, a little goes a long way.

• Recommended pairing: Nº.4FINE shampoo for system benefits.
• Application: mid-lengths to ends, 1–3 minutes dwell time.
• Usage estimates: 250 mL yields up to ~50 applications (5 mL each).
• Rinse well; style as usual to reveal lasting lift and manageability.

What results can I expect after one wash?

From the first use, hair becomes easier to detangle, feels softer, and gains immediate volume and lift at the root. Continued use as part of the Nº.4FINE + Nº.5FINE regimen supports stronger, more resilient hair over time without weighing fine strands down.

• Instant, clinically proven increase in volume and lift.
• Smoother, more manageable hair with improved detangling.
• Weightless hydration for softness without limpness.
• Supports length retention by reducing breakage.

Who is this for? Nº.5FINE is tailored for people with fine-textured hair—whether straight, wavy, curly, or coily—who want more body, easier styling, and strengthened strands without the heaviness of traditional conditioners. It suits anyone seeking color-safe, vegan haircare that repairs everyday damage and defends against future breakage while delivering noticeable lift and manageability in a single wash.
