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

Olaplex Nº.5FINE Bond Maintenance™ Lightweight Volumizing Conditioner is a weightless, bond-repairing conditioner that instantly adds lift, improves manageability, and helps reduce breakage for fine hair.

Designed specifically for fine textures, this concentrated conditioner targets everyday damage while keeping hair light and bouncy. It combines Olaplex’s patented bond-building technology with low-molecular-weight hydrators and flexible polymers to restore strength, smoothness, and root lift without weighing strands down. Use it after Nº.4FINE Bond Maintenance Shampoo for best results; a little goes a long way, so a single 250 mL bottle can deliver many applications.

How does Nº.5FINE repair damage without heavy conditioning?

Rather than coating the hair with heavy oils, Nº.5FINE rebuilds damaged disulfide bonds at a molecular level to restore structural integrity. Lightweight humectants and flexible polymers provide slip and hydration without flattening fine hair, so strands feel softer but retain volume.

• Patented OLAPLEX bond-building ingredient targets weakened bonds.
• Low molecular weight hyaluronic acid hydrates without heaviness.
• Flexible polymers boost root lift and body for instant volume.

Will this conditioner add real volume all day?

Yes — the formula is clinically shown to increase visible volume instantly and maintain lift through the day when used as part of the Nº.4FINE + Nº.5FINE system. The lightweight texture provides support at the roots while smoothing mid-lengths and ends for an overall fuller look.

• Clinically proven to double visible volume instantly and sustain lift.
• Builds body at the root without sticky residue or weight.
• Helps hair hold style better thanks to flexible polymers.

How does it help with detangling and manageability?

The conditioner delivers immediate slip to ease combing and reduce friction, which limits mid-shaft and end breakage during styling. Hair becomes smoother and more manageable in a single wash, making daily grooming quicker and less damaging.

• Improves detangling by up to 90% in clinical testing when used in the system.
• Reduces breakage and enhances resilience for easier styling.
• Leaves hair soft and controllable without excess weight.

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

Nº.5FINE is formulated to be color-safe and compatible with chemically treated hair. It’s dermatologist-tested and vegan, making it suitable for a wide range of hair care routines that need both repair and lift.

• Color-safe formulation preserves treated hair tones.
• Vegan and dermatologist tested for broad compatibility.
• Works across porosity levels and curl patterns, from straight to coily.

How to use: after cleansing with Nº.4FINE Bond Maintenance Shampoo, apply to clean, wet hair from mid-lengths to ends. Leave on 1–3 minutes, then rinse thoroughly. For best outcomes, use as part of the Nº.4FINE + Nº.5FINE system; average application size is small, so a 250 mL bottle offers numerous uses.

Who is this for? Nº.5FINE is crafted for people with fine hair seeking weightless hydration, added body, and reduced breakage. It's ideal for those who want visibly fuller strands without heavy conditioning—suitable for straight, wavy, curly, or coily textures and safe for color or chemical treatments.
