Olaplex N°.4FINE Volumizing Bond Maintenance Shampoo 250 mL — Lightweight Repair & Root Lift for Fine Hair

Olaplex N°.4FINE Bond Maintenance™ Volumizing Shampoo is an ultra-light shampoo formulated to strengthen, repair and add lasting volume to fine hair without weighing it down.

Designed specifically for finer hair types, this 250 mL shampoo combines Olaplex's bond-building technology with lightweight hydrators and flexible polymers to remove buildup, reduce breakage risk, and create lift at the root. Use it as the cleansing step in a routine with No.5FINE Conditioner for best results; clinically tested performance refers to use within that system.

How does No.4FINE build volume without drying or stiffening fine strands?

No.4FINE uses low-weight volumizing agents and a hydra-balancing formula that lifts hair at the root while maintaining pliability. Instead of coating strands with heavy oils or silicones, it deposits flexible polymers that create body and bounce while leaving hair touchable.

• Flexible polymers add lift and root support without stiffness
• Low Molecular Weight Hyaluronic Acid hydrates without heaviness
• Hydra-Balancing Matrix prevents over-conditioning that can flatten fine hair

Will this shampoo help damaged or chemically treated fine hair?

Olaplex N°.4FINE incorporates bond-maintenance technology to fortify hair structure and reduce susceptibility to breakage. When paired with No.5FINE Conditioner, the system is clinically evaluated to repair and help prevent future damage from styling, environmental exposure, and salon services.

• Formulated to support weakened bonds in bleached or processed hair
• Clinically shown benefits when used as part of the No.4FINE/No.5FINE regimen
• Gentle cleansing removes buildup that can stress fragile ends

How should I use No.4FINE for best results and how often?

Apply to wet hair, lather, and rinse thoroughly; follow with No.5FINE Conditioner for optimal conditioning and volume. Frequency depends on scalp oiliness and styling habits, but most users with fine hair will benefit from regular use two to four times per week to maintain lift and manageability.

• Wet hair thoroughly, apply a quarter-sized amount, massage into scalp and lengths
• Rinse and follow with No.5FINE Conditioner for balanced hydration
• Adjust frequency based on oiliness and styling; ideal for regular cleansing

What key ingredients create the balance between repair, hydration, and volume?

The formula blends Olaplex’s proprietary bond-maintaining actives with lightweight humectants and flexible polymers. Together these ingredients strengthen hair internally, attract moisture externally, and provide perceptible fullness without residue.

• Bond-maintenance technology supports strand integrity and reduces breakage risk
• Low Molecular Weight Hyaluronic Acid restores softness and manageability
• Flexible polymers and hydra-balancing components maximize lift and volume

Who is this for: Olaplex N°.4FINE Bond Maintenance™ Volumizing Shampoo is intended for people with fine to fine-medium hair who want increased body and resilience without heavy conditioning. It suits hair that’s color-treated, highlighted or chemically processed and for anyone seeking a gentle, bond-supporting cleansing step that pairs with No.5FINE for measurable strength, volume, and improved manageability.
