Nexxus Ultralight Smooth Shampoo & Conditioner Duo, 13.5 oz Each — Weightless Frizz‑Blocking, Sulfate‑Free

Nexxus Ultralight Smooth Shampoo & Conditioner is a salon-grade, protein-infused system that gently cleanses and forms an invisible, weightless barrier to help block frizz and smooth hair without weighing it down.

Designed for hair that reacts to humidity and needs lightweight smoothing, this duo uses a PROTEINFUSION blend of almond protein and white jasmine to strengthen strands from the inside while Bio-mimetic 18-MEA recreates a hydrophobic surface on the cuticle. The formula is silicone- and sulfate-free, so it cleanses and seals without heavy residue, leaving hair glossy, touchable, and more manageable when used as a system.

How does this system reduce frizz in humid weather?

Ultralight Smooth combines a cuticle-laminating technology with moisture-balancing proteins to help repel humidity and limit hair fiber swelling that causes frizz. When used together, the shampoo and conditioner create a thin, invisible layer around each strand that deflects moisture from the environment.

• Bio-mimetic 18-MEA mimics natural lipids to seal the cuticle.
• Weightless barrier reduces fiber expansion in up to high humidity.
• System use (shampoo + conditioner) maximizes frizz-blocking performance.

Will it clean hair without making it heavy or flat?

The sulfate-free shampoo cleanses oils and buildup while preserving the lightweight feel of hair. Proteins and hydration agents in the conditioner replenish and seal without leaving a heavy film, so hair retains bounce and movement after rinsing.

• Sulfate-free formula removes impurities gently.
• Conditioner provides hydration without weight.
• Leaves hair soft, shiny, and full of movement rather than limp.

What are the key ingredients and how do they work together?

The formula pairs almond-derived protein and white jasmine with a biomimetic lipid (18-MEA) to address both internal strength and external protection. Proteins help fortify weakened fibers while the lipid-like ingredient smooths the cuticle to improve shine and reduce friction.

• Almond protein supports internal strand strength and resilience.
• White jasmine contributes to conditioning and sensory experience.
• Bio-mimetic 18-MEA helps recreate hair’s natural hydrophobic surface for smoother cuticles.

How should I use the Ultralight Smooth system for best results?

Start by massaging the shampoo into wet hair to create a rich lather, rinse, then apply the conditioner from root to tip and leave it on for a few minutes before rinsing. For enhanced control, follow with Ultralight Smooth Frizz Defy Hair Serum to target flyaways and boost longevity.

• STEP 1: Wash with Nexxus Ultralight Smooth Shampoo; rinse thoroughly.
• STEP 2: Apply Nexxus Ultralight Smooth Conditioner; leave in briefly then rinse.
• STEP 3: Finish with the matching Frizz Defy Serum for extra control.

Who is this for: Nexxus Ultralight Smooth is best suited for people with dry, frizz-prone hair who want salon-quality smoothing without weight. It benefits those seeking stronger fibers, a sleeker finish, and humidity resistance while avoiding silicones and sulfates. Ideal for fine-to-medium hair textures that need hydration and polish without losing natural bounce.
