Nexxus KERAPHIX Damage Repair Shampoo 33.8 fl oz — Keratin-Powered Strength & Shine

Nexxus KERAPHIX Shampoo is a keratin-powered cleansing treatment that rebuilds and shields damaged hair to restore strength, softness and shine.

Built on Nexxus protein science, this full-size 33.8 fl oz formula uses KRT (Keratin Resistance Therapy) and liquid crystal amino acids to target hair weakened by coloring, bleaching, heat, and styling. Rather than masking symptoms, the shampoo helps reconstruct internal bonds and seal the cuticle so strands become more resilient and easier to manage. It’s intended for use as part of the Keraphix regimen to visibly reduce breakage and improve hair texture with continued use.

How does this shampoo rebuild hair that’s been chemically treated?

The formula delivers concentrated keratin-related ingredients and crystalline amino acids that work inside the fiber to reconnect strands and reinforce areas where protein has been lost. When used in the Keraphix system, it supports the rebuilding of cuticle-to-cortex structure to improve tensile strength.

• Contains 5.9% KRT technology with liquid crystal serine amino acid to target internal repair.
• Reconstructs weakened bonds caused by bleaching, coloring, and chemical services.
• Helps restore hair to a stronger, more resilient state comparable to less damaged hair when used as a system.

What immediate benefits will I notice after one wash?

This shampoo is formulated to cleanse while delivering instant visible change: hair feels smoother, detangles more easily, and looks glossier after the first use. The surfactants are balanced to add moisture without leaving heavy residue, so hair appears less frizzy and more reflective.

• Instant smoothing effect that reduces surface roughness and tangling.
• Deep moisture to revive dry, brittle strands without buildup.
• Seals cuticle cracks to improve shine and manageability quickly.

Will it help protect hair from future heat and styling damage?

While no shampoo can fully prevent all future damage, its repair-and-seal approach helps strengthen strands so they better resist stress from heat and styling. The cuticle-sealing action reduces vulnerability to breakage and split ends, making hair easier to style with less force.

• Creates a protective outer layer that reduces friction during styling.
• Improves elasticity so hair bends and returns with less snapping.
• Designed to work alongside Keraphix conditioner and treatment for enhanced protection.

How should I incorporate this into my routine for best results?

Use this shampoo as part of the full KERAPHIX regimen—shampoo, conditioner, and the Liquid Crystallizer treatment—to maximize rebuilding and protection. Apply to wet hair, lather, rinse, and follow with conditioner; use the concentrated treatment periodically for intensive repair on heavily processed areas.

• Use regularly for ongoing reinforcement of protein and cuticle health.
• Pair with Keraphix Conditioner and Liquid Crystallizer for optimal outcomes.
• Suitable for frequent stylers who want to restore strength while cleansing.

Who is this for: Nexxus KERAPHIX Shampoo is geared toward people with chemically processed, heat-stressed, or visibly damaged hair who want a science-driven approach to repair. It’s appropriate for those seeking both immediate smoothing and longer-term restoration when used consistently in the Keraphix system. If you want a shampoo that focuses on rebuilding internal strength, reducing breakage, and improving manageability, this professional-strength option is designed to help.
