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

Nexxus Unbreakable Anti Breakage Conditioner is a strengthening, weightless conditioner formulated to reduce breakage and add measurable fullness to fine or thin hair using DURAPLEX FORTIFIER technology and a thickening complex.

Fine and thin hair has a slimmer cortex and fewer protective cuticle layers, which makes it more susceptible to snapping, tangling, and limp styles. Nexxus applies decades of protein science to rebuild hair structure from the inside out: this conditioner optimizes pH, delivers bond-reforming proteins, and shields cuticles while providing lift without heaviness. The result is improved elasticity, reduced hair fall from breakage, and hair that appears thicker and more resilient over time.

How does this conditioner reduce breakage for delicate hair?

The formula includes DURAPLEX FORTIFIER technology, a protein-enriched matrix that targets weakened areas of the strand and reinforces internal structure. By building internal strength and protecting the cuticle, the conditioner helps hair resist snapping during styling and brushing. Use consistently with the matching shampoo for the best system results.

• Contains 9.0% DURAPLEX FORTIFIER Technology for bond support
• Optimizes hair pH to strengthen the core of each strand
• Cuticle-protecting actives reduce external abrasion and friction
• Proven reduction in hair fall when used as a system versus non-conditioning shampoo

Will this make my fine hair look fuller without weighing it down?

Yes—this conditioner combines lightweight polymers and a thickening complex that lift and plump strands without heaviness. It deposits just enough conditioning to smooth and add body while preserving natural movement. The finishing effect is more visible fullness and lasting volume that doesn’t collapse by midday.

• Weightless volumizing polymers add lift at the root and body along the shaft
• Thickening complex creates fuller-looking strands from within
• Maintains manageable texture so styling remains easy
• Consumer-tested: majority notice more body and thickness

Can this product restore style resilience and allow restyling?

The DURAPLEX system includes bond-building components that help hair reform when styled heat or mechanical stress causes temporary disruption. That means styles can be refreshed and reshaped more easily because the conditioner supports reformable bonds rather than introducing heavy, static coatings. Expect smoother, more elastic hair that tolerates daily styling better.

• Bond-building technology supports reformable internal connections
• Improves elasticity so hair bounces back after tension
• Leaves cuticle smooth for easier detangling and restyling

How should I use the conditioner for optimal results?

For best performance, use as part of the Nexxus Unbreakable system: shampoo first to cleanse and prepare the cortex, then apply conditioner focusing on mid-lengths to ends. Leave in for a few minutes to allow protein and cuticle actives to penetrate, then rinse thoroughly. Regular use helps maintain strength and visible fullness over time.

• Pair with the Unbreakable shampoo to maximize anti-breakage benefits
• Apply from mid-shaft to ends; avoid heavy application at roots
• Leave on for several minutes before rinsing for deeper conditioning
• Use consistently to see reduced hair fall and improved body

Who is this for: Nexxus Unbreakable Anti Breakage Conditioner is designed for people with fine, thin, or fragile hair who want to reduce breakage, add weightless volume, and improve strand resilience. It’s ideal for anyone who frequently styles, brushes, or chemically treats hair and needs a strength-building conditioner that won’t weigh hair down. Salon-tested protein science offers a daily-strengthening option for those aiming to rebuild hair from within while keeping natural movement and shine.
