Nexxus KERAPHIX Repair Shampoo 33.8 fl oz — Keratin Damage Repair, Strengthening & Shine

Nexxus KERAPHIX Shampoo is a keratin-powered repair shampoo designed to rebuild weakened hair fibers and help restore strength, softness, and shine after chemical or heat damage.

Every time hair is colored, heat-styled, or chemically treated, protein structure can be altered and strands become fragile, rough, and prone to breakage. Nexxus KERAPHIX uses Keratin Resistance Therapy (KRT) with liquid crystal amino acids to target damage from cuticle to cortex, delivering deep moisture while sealing and reconstructing bonds so hair becomes more resilient and easier to style.

How quickly will I see improvement in damaged hair?

Visible change can appear after a single wash: the formula offers instant smoothing and helps seal cuticle cracks that cause roughness and tangling. Ongoing use with the full KERAPHIX regimen builds internal strength to reduce breakage over time.

• Immediate: smoother, more manageable feel after one use
• Short term: reduced tangles and increased shine within a few washes
• Long term: rebuilt protein bonds and measurable strength when used regularly as a system

What is Keratin Resistance Therapy and why does it matter?

KRT is a protein-focused technology that helps reconstruct hair’s internal network using liquid crystal amino acids. Instead of only coating the surface, it works to replenish and realign protein where disulfide bonds and amino acids have been depleted by chemical or heat processes.

• Targets cortex and cuticle for deeper repair
• Contains concentrated keratin-derived amino acids for rebuilding
• Helps hair resist future damage after bonds are strengthened

Will this shampoo make my hair feel heavy or leave buildup?

KERAPHIX is formulated to deliver rich moisture and softness without weighing hair down when used as directed. The shampoo cleanses while infusing reconstructive proteins and sealing the outer layer; follow with the matching conditioner and periodic treatment for balanced results.

• Deep hydration that avoids greasy residue
• Seals the cuticle to improve smoothness and manageability
• Best paired with Keraphix Conditioner and Liquid Crystallizer for full effect

How does this help styling and daily manageability?

By restoring elasticity and reducing breakage, hair becomes easier to detangle, shape, and style. Improved strength means strands hold up better under heat and frequent styling, creating a smoother base for any look.

• Increases elasticity so hair bends and recovers rather than snaps
• Enhances softness and slip for easier comb-through and styling
• Helps hair appear shinier and less frizzy under heat or humidity

Who is this for: Nexxus KERAPHIX Shampoo is intended for people with chemically-treated, heat-styled, or visibly weakened hair who want to rebuild protein strength and improve texture. It’s suited to those seeking salon-level repair in a daily-use shampoo format and performs best when used together with the KERAPHIX Conditioner and Liquid Crystallizer treatment as a complete regimen.

Note: Results vary by hair type and condition. The KERAPHIX system is designed to repair visible damage and enhance hair resilience but does not replace professional advice for severe scalp or hair disorders.
