Nexxus Unbreakable Anti-Breakage Shampoo for Fine & Thin Hair, 13.5 oz — Strengthening & Volumizing

Nexxus Unbreakable Anti Breakage Shampoo is a strengthening, weightless shampoo formulated to reduce breakage and add lasting volume to fine, thin hair using DURAPLEX FORTIFIER technology and a thickening complex.

Fine and thin hair has a narrower cortex and fewer protective cuticle layers, making it more susceptible to snapping, tangling, and limpness. Nexxus applies protein science in this formula to rebuild internal strength, protect the cuticle, and create fuller-looking hair without heavy residue. The result is reduced hair fall from breakage, improved elasticity, and lift that stays all day while remaining sulfate- and silicone-free.

How does this shampoo strengthen fragile fine hair?

The formula uses a 2.9% DURAPLEX FORTIFIER technology with a targeted thickening complex to reinforce hair from the inside out. It optimizes pH to help rebuild protein structure in the cortex while cuticle actives smooth and seal the outer layer, reducing the chances of fiber breakage.

• 2.9% DURAPLEX FORTIFIER for internal protein reinforcement
• Cuticle-protecting actives to shield hair from external damage
• pH-optimized formula to support structural resilience and elasticity

Will it add volume without weighing my hair down?

Yes — the shampoo delivers weightless lift using flexible polymers and a thickening complex designed specifically for fine, thin strands. It builds fullness from the core of the fiber so hair appears and feels thicker, while leaving no heavy film or buildup behind.

• Flexible volumizing polymers for all-day lift
• Thickening complex to increase perceived density
• Sulfate- and silicone-free for clean, non-greasy results

How much breakage reduction can I expect and what evidence supports it?

Nexxus reports up to 97% less hair fall due to breakage when used as part of the system versus a non-conditioning shampoo, supported by consumer study results. Independent-feeling benefits include more body and a thicker feel, with a salon-grade protein approach rather than a quick fix.

• 97% less hair fall from breakage (system vs. non-conditioning shampoo)
• 91% of users noticed more body/volume in a consumer study
• 87% of users reported their hair felt thicker after use

Is this shampoo safe for color-treated or chemically processed hair?

The sulfate- and silicone-free formula is gentler on color and on chemically treated hair than many traditional shampoos, while its protein-based fortification supports structural repair. As with any salon-strength product, pair it with compatible conditioners or treatments for best results.

• 0% sulfates and 0% silicones to reduce striping and buildup
• Protein matrix supports repair for chemically altered strands
• Works best within the complete Unbreakable system for optimal protection

Who this is for: This shampoo is made for people with fine, thin hair who want salon-level strengthening and visible volume without heaviness. It's suited to anyone experiencing breakage from styling, brushing, or chemical services and to those seeking a science-driven, protein-focused routine that prioritizes internal hair health alongside surface smoothness.
