Nexxus Ultralight Smooth Smoothing Conditioner 13.5 oz — Frizz Deflector Technology, Weightless Hydration for Dry Hair

Nexxus Ultralight Smooth Smoothing Conditioner is a lightweight, protein-powered conditioner that seals the cuticle and repels humidity to leave dry, frizz-prone hair smoother and shinier without weighing it down.

Built on Nexxus protein science, this 13.5 oz conditioner uses Frizz Deflector technology with Biomimetic 18‑MEA to restore the hair’s lipid surface and create a hydrophobic, weightless barrier. It targets the specific protein- and lipid-related breakdowns that make hair porous and prone to frizz, laminating the cuticle for instant shine and delivering internal protein actives to improve strength over time. The formula is aimed at dry, frizz-prone hair types that need smoothness and movement rather than heavy conditioning.

How does this conditioner reduce frizz without feeling heavy?

The conditioner forms an invisible, ultralight shield that smooths the cuticle and repels moisture, so hair resists humidity while keeping natural bounce. Instead of coating strands with heavy oils, it rebuilds a lipid-like surface to create a hydrophobic finish.

• Biomimetic 18‑MEA laminates the cuticle for a sleek surface
• Weightless film prevents moisture absorption that causes swelling
• Leaves hair soft and bouncy rather than flat or greasy

Will it make dry or damaged hair stronger over time?

Yes—this formula combines surface-repairing lipids with protein strength actives to address both the outer cuticle and the inner cortex. Regular use supports improved resilience and helps hair perform better through styling and environmental stress.

• Protein actives penetrate to reinforce strands from within
• Cuticle sealing reduces future abrasion and moisture damage
• Designed for repeated use as part of a smoothing regimen

How long does frizz control last and how is it measured?

Nexxus reports frizz protection for up to 72 hours when used as part of the Ultralight Smooth system, achieved by blocking humidity and maintaining the cuticle seal. Longevity depends on hair type, styling, and environmental exposure.

• System approach (shampoo + conditioner) boosts performance
• Cuticle lamination reduces immediate moisture uptake
• Results vary with climate, activity, and product frequency

Is this suitable for my hair type and styling routine?

This conditioner is formulated for dry, frizz-prone, or chemically processed hair that needs smoothness without weight. It works well for those who blow-dry, air-dry, or use heat tools and want a sleeker finish without buildup.

• Best for dry, porous, or frizz-prone hair textures
• Light enough for fine to medium hair when used sparingly
• Compatible with heat styling and finishes well under serums or oils
