Nexxus Unbreakable Anti-Breakage Conditioner for Fine & Thin Hair — 13.5 oz, DURAPLEX Fortifier

Nexxus Unbreakable Anti-Breakage Conditioner is a strengthening, weightless conditioner formulated to reduce breakage and add volume to fine and thin hair using DURAPLEX FORTIFIER technology.

Fine and thin hair tends to lose protein structure more easily, which makes it fragile, prone to tangles, and susceptible to visible thinning. Nexxus Unbreakable was developed to rebuild hair from the inside out: a formulation that targets the protein matrix and cuticle layer to reinforce strands, reduce hair fall caused by breakage, and deliver everyday fullness without heaviness. The formula pairs bond-supporting actives with flexible polymers and a thickening complex so styling is easier and hair feels stronger over time.

How does this conditioner actually reduce breakage?

The product uses DURAPLEX FORTIFIER technology—a concentrated protein and cuticle-active system that restores internal strength and shields the hair surface. By optimizing pH and rebuilding weakened bonds, the conditioner helps strands tolerate routine styling and handling with less shredding and snapping.

• Contains 9.0% DURAPLEX FORTIFIER technology to reinforce the protein matrix.
• Optimizes hair pH to protect internal structure and elasticity.
• Bond-building ingredients support reformable links so hair recovers from mechanical stress.

Will it add volume to fine, thin hair without weighing it down?

Yes—this conditioner is formulated to deliver weightless lift by combining a thickening complex with flexible polymers. Those ingredients create fuller-looking hair and maintain all-day body while avoiding the heavy finish common with richer conditioners.

• Thickening complex increases strand diameter for a thicker appearance.
• Lightweight conditioning agents smooth the cuticle without buildup.
• Flexible polymers provide lift and long-lasting volume.

How quickly will I notice differences in strength and body?

Many users report immediate improvements in manageability and a reduction in visible breakage on the brush after regular use with the matching Unbreakable shampoo. Structural benefits build over time as the formulation restores protein continuity and cuticle integrity.

• Immediate: smoother cuticle and easier detangling after first use.
• Short term: less hair fall from breakage with consistent use.
• Ongoing: strengthened, fuller-feeling hair as internal bonds rebuild.

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

The conditioner focuses on bond-building and cuticle protection, which supports chemically treated hair by helping restore and maintain structural integrity. It’s designed to be gentle and to work alongside color and smoothing services, though results vary by treatment type.

• Bond-supporting actives help preserve color-treated strands’ resilience.
• Cuticle protection minimizes external abrasion that can fade color.
• Works best when paired with the matching Unbreakable shampoo for system benefits.

Who this is for: Nexxus Unbreakable Anti-Breakage Conditioner is intended for people with fine, thin, or fragile hair who want to reduce hair fall caused by breakage while adding visible thickness and lift. It’s a good match for those who style frequently, seek weightless volume, or use color and chemical services and need a strengthening conditioner that supports bond repair and cuticle protection.
