Nexxus Ultralight Smooth Conditioner for Frizzy Hair 13.5 oz — weightless frizz control, adds shine

Nexxus ULTRALIGHT SMOOTH® Conditioner is a weightless smoothing treatment that seals the cuticle, restores surface lipids, and fights frizz up to 72 hours without weighing hair down.

Designed for hair that becomes puffy, rough, or reactive in humid conditions, this 13.5 oz conditioner uses targeted protein science to rebuild and protect each strand. Instead of masking frizz with heavy oils, the formula relies on Biomimetic 18-MEA and protein-strength actives to recreate hair’s natural lipid layer, form an invisible hydrophobic shield, and add internal resilience. The result is smoother texture, instant shine, and manageable movement that keeps hair soft and buoyant.

How does this conditioner reduce frizz without making hair flat?

Rather than coating strands with heavy silicones, the formula laminates the cuticle and restores the hair’s own lipids to create a lightweight barrier. That hydrophobic layer repels humidity and smooths the surface so strands slide together, producing sleekness without limpness.

• Biomimetic 18-MEA rebuilds the natural lipid film for moisture resistance.
• A weightless shield forms an invisible lamination over each strand.
• Leaves body and bounce by avoiding heavy conditioning agents.

What immediate benefits will I see after one use?

Right after rinsing, hair looks glossier and feels softer because the cuticle is sealed and light-reflecting surfaces are restored. You’ll notice reduced surface roughness, easier detangling, and an overall sleeker appearance that handles styling more predictably.

• Instant shine from a sealed, smoother cuticle.
• Reduced tangles and easier comb-through.
• Soft, touchable texture with visible smoothing.

How long does the frizz protection last and what conditions does it handle?

The system is formulated to defend against humidity-induced swelling for up to 72 hours under normal environmental exposure. It targets common protein-related issues—cuticle disruption, lipid loss, and increased porosity—to limit water absorption and maintain a controlled, smooth structure.

• Up to 72 hours of frizz defense when used in the ULTRALIGHT SMOOTH system.
• Reduces hair’s responsiveness to humidity by restoring lipid barriers.
• Helps keep style intact from day to day with less re-styling required.

Does this conditioner strengthen hair or just smooth the surface?

It does both: surface lamination for immediate smoothness and protein-strength actives that help repair internal structure over time. The proteins work to reinforce weak points along the strand so hair becomes more resilient while staying light and flexible.

• Protein actives support internal repair and lasting strength.
• Surface lamination maintains a sleek exterior and reduces breakage from friction.
• Continuous use improves manageability and durability of styles.

Who is this for: Nexxus ULTRALIGHT SMOOTH® Conditioner is aimed at people with frizz-prone, dry, or porous hair who want humidity resistance without sacrificing volume. It suits chemically treated, heat-styled, or naturally wavy and curly textures that need smoothing plus restorative protein support. Use as part of the ULTRALIGHT SMOOTH system for best results, or pair with your preferred Nexxus shampoo for a balanced routine that minimizes frizz while preserving movement and shine.
