Nexxus KERAPHIX Shampoo & Conditioner Set 33.8 oz 2‑Pack — Damaged Hair Repair, Keratin Strengthening

Nexxus KERAPHIX™ Shampoo + Conditioner Set is a salon-strength repair duo designed to rebuild weakened strands and restore softness, shine, and resilience to damaged hair.

This two-piece system combines KRT Keratin Resistance Therapy with liquid crystal serine amino acids to target damage from coloring, bleaching, heat styling and chemical services. The formula works both at the surface and deep inside the fiber to reconstruct bonds that give hair its structure, improving elasticity and reducing breakage while adding moisture and manageability. Packaged in generously sized 33.8 oz bottles, this set is intended for regular use to progressively strengthen hair back toward a healthier state.

How does the KERAPHIX system rebuild hair strength?

The set uses KRT technology—keratin-focused peptides and liquid crystal amino acids—to penetrate the cortex and support the cuticle, helping strands resist future breakage. Shampoo begins the process by cleansing and delivering reparative actives; the conditioner seals and reinforces the reconstructed bonds while smoothing the outer layer.

• KRT Keratin Resistance Therapy targets bond repair from cuticle to cortex.
• Liquid crystal serine amino acids help replenish amino-acid content lost through treatments.
• Shampoo delivers 5.9% KRT actives for initial reconstruction and cleansing.
• Conditioner provides 12.6% KRT actives for deeper reinforcement and sealing.

Will this set help hair damaged by color and heat styling?

Yes—KERAPHIX is formulated specifically for damage caused by chemical processing and frequent heat. By restoring amino acids and rebuilding internal structure, it reduces visible signs of stress like dullness, roughness, and split-prone strands, while helping hair look smoother and shinier.

• Designed to address discoloration-related fiber weakening from coloring and bleaching.
• Reconstructs disulfide and peptide bonds weakened by heat tools.
• Improves manageability so styling requires less tension and heat over time.

How will my hair feel and behave after using the shampoo and conditioner?

With consistent use, hair becomes softer, more elastic, and easier to detangle and style. The conditioner delivers moisture without heavy buildup, so strands feel fluid and look glossy rather than flat or weighed down.

• Noticeable softness and smoother cuticle surface after conditioning.
• Improved elasticity reduces breakage during brushing and styling.
• Provides shine and slip for effortless comb-through and styling readiness.

How should I integrate this set into my routine for best results?

Use the shampoo to gently cleanse and apply the conditioner focusing on mid-lengths to ends to lock in moisture and repair where damage concentrates. For severely compromised hair, repeat use and consider pairing with a KERAPHIX treatment mask for periodic deep rebuilding.

• Shampoo: apply to wet hair, lather, rinse; repeat if needed for heavy product or buildup.
• Conditioner: leave on 1–3 minutes for standard repair, longer for extra conditioning.
• Supplemental weekly treatment boosts repair for highly processed or brittle hair.

Who is this for: Nexxus KERAPHIX Shampoo + Conditioner Set suits people with chemically treated, heat-styled, or otherwise weakened hair seeking a science-backed program to restore strength and manageability. It’s ideal for anyone wanting salon-grade protein repair in larger, value-size bottles for frequent use. Avoid if you prefer protein-free formulations or have very fine hair that becomes limp from heavy conditioners; in those cases, use sparingly and concentrate conditioner on ends only.
