Nexxus Keraphix Shampoo for Damaged Hair — 33.8 oz salon-size, protein repair & shine

Nexxus KERAPHIX™ Shampoo is a salon-grade cleanser formulated to rebuild hair protein and visibly repair extreme damage while restoring softness and shine.

Every styling session, color service, and heat tool reshapes the protein structure of your hair. Over time those changes can leave strands weak, rough, and prone to breakage. Nexxus KERAPHIX Shampoo uses targeted protein science — KRT Keratin Resistance Therapy with liquid crystal serine amino acids — to reconstruct internal bonds and seal the outer layer, helping hair recover strength, elasticity, and manageability.

How does this shampoo rebuild damaged hair?

KERAPHIX works by delivering keratin-building ingredients deep into the fiber to replenish lost amino acids and support bond reconstruction from cortex to cuticle. The formula focuses on both internal repair and sealing the outer cuticle to reduce future deterioration.

• Contains 5.9% KRT technology with liquid crystal serine amino acids to target structural rebuilding.
• Reconstructs bonds along the hair shaft to improve tensile strength.
• Seals cuticle cracks to reduce friction, tangling, and surface roughness.

What visible benefits can I expect after using KERAPHIX Shampoo?

From the first full regimen, hair looks and feels healthier: smoother, shinier, and less prone to breakage. In combination with the full Keraphix system, the shampoo helps hair appear stronger and easier to style.

• Targets dryness and brittleness to restore a soft, fluid texture.
• Improves shine by smoothing the cuticle and reducing frizz.
• Helps hair resist damage from coloring, heat, and chemical services.

How should I use this 33.8 oz salon-size bottle for best results?

Apply to wet hair, lather gently, and rinse; for maximum repair follow with Keraphix Conditioner and Liquid Crystallizer treatment as part of the system. Regular use rebuilds internal strength while the conditioner and treatment lock in moisture and protection.

• Use as part of the Keraphix regimen for optimum repair and 24X stronger hair vs. non-conditioning shampoo.
• Leave-in the treatment step (Liquid Crystallizer) as directed for intensive reconstruction.
• Sized at 33.8 oz for frequent use or salon stations, offering extended supply.

Will this shampoo weigh down fine hair or cause buildup?

KERAPHIX Shampoo is formulated to deliver deep moisture without heavy residue when used as directed. It focuses on repairing and sealing damage rather than coating hair, so normal rinsing and routine styling should maintain natural bounce and movement.

• Designed to revive dry, brittle strands without leaving film when rinsed thoroughly.
• Helps restore elasticity so hair remains manageable and style-ready.
• Best paired with the full system; occasional clarifying helps if you use many styling products.

Who is this for: Nexxus KERAPHIX Shampoo in the 33.8 oz size is designed for people with medium-to-severely damaged hair from coloring, lightening, heat, chemical services, or frequent styling. It's ideal for those seeking a salon-grade, science-backed repair regimen to rebuild strength, reduce breakage, and restore softness and shine over time.

Note: Results are based on system use and studies comparing the Keraphix regimen to non-conditioning shampoo; individual outcomes vary.
