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

This specially engineered conditioner combines Olaplex’s patented bond-building technology with lightweight volumizing polymers and low molecular weight hyaluronic acid to strengthen and hydrate fine textures without weighing them down. Designed to work on straight, wavy, curly, and coily fine hair, Nº.5FINE focuses on reinforcing hair structure, improving detangling, and delivering noticeable root lift after one wash when used alone or as part of the Nº.4FINE + Nº.5FINE system.

How quickly will I see more volume and lift?

Most users notice immediate lift and increased body after the first application because the flexible polymers provide root lift while the concentrated formula coats strands without heaviness. Results are clinically supported for instant and all-day volume when used as directed.

• Doubles visible volume instantly and maintains lift throughout the day.
• Flexible polymers add root support without sticky residue.
• Lightweight texture prevents collapse on fine strands.

Can this conditioner repair damage without weighing my hair down?

Yes—Olaplex’s patented Bond Building Technology targets compromised disulfide bonds to reinforce hair strength at a molecular level while the Hydra-Balancing Matrix and low molecular weight hyaluronic acid deliver hydration that won’t sit heavily on fine hair. The result is stronger, softer hair with reduced breakage and improved resilience.

• Rebuilds bonds to reduce breakage and protect length.
• Low molecular weight hyaluronic acid adds weightless moisture.
• Clinically shown to repair everyday damage in one wash.

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

Apply to clean, wet hair after shampooing with Nº.4FINE or any suitable cleanser. Work from mid-lengths to ends, leave on for 1–3 minutes, then rinse thoroughly. A little goes a long way due to the concentrated formula—use sparingly on finer textures.

• Recommended: pair with Nº.4FINE Bond Maintenance Shampoo for optimal benefits.
• 250 mL yields up to ~50 applications based on average 5 mL use.
• Suitable for color-treated and chemically processed fine hair.

Is this safe for different curl patterns and treated hair?

Nº.5FINE is formulated for straight, wavy, curly, and coily fine hair across all porosity levels and is color-safe and dermatologist tested. It’s vegan and appropriate for chemically treated hair when used as part of a gentle maintenance routine.

• Dermatologist tested and vegan-friendly.
• Color-safe for treated or highlighted hair.
• Works across porosity levels to balance hydration and manageability.

Who is this for: Olaplex Nº.5FINE is ideal for anyone with fine hair seeking more body and resilience without extra weight—whether your hair is straight, wavy, curly, or coily, natural or chemically treated. Choose this conditioner if you want to reduce breakage, improve detangling, and enjoy lasting root lift with a refined, lightweight finish.
