Hair is made up of protein. Every touch, every treatment, every style you love—it all rewrites your hair’s protein. When protein is damaged, hair’s look and feel is compromised. That’s why Nexxus uses protein science not just to repair hair but to restore its ability to perform. It isn't about one perfect hair day. It's about a lifetime of healthy hair, built strand by strand. Frequent heat styling and chemical processing can break down disulfide bonds and strip essential amino acids, leading to cuticle erosion and damage deep within the hair fiber. This makes strands weak, dull, tangled, harder to style, and less smooth and shiny. KERAPHIX, our extreme damage repair collection, is powered by KRT Keratin Resistance Therapy with liquid crystal serine amino acid to rebuild internal strength from inside out. Repair and resist visible damage from coloring, bleaching, highlighting, styling, heat and more with 24X stronger hair restored to be as strong as virgin hair. This shampoo for damaged hair provides deep moisture to revive dry, brittle strands and KRT technology seals the outer layer to restore elasticity—so hair is shiny, feels soft, resilient, and ready to bounce back with every style. Nexxus, the protein science behind powerful hair since 1979. *System vs. non-conditioning shampoo Based on a breakage study on bleached treated hair with Keraphix Shampoo & Conditioner + Treatment vs. virgin hair.

Frequently Asked Questions
What makes Nexxus KERAPHIX Shampoo feel like a premium salon product compared to drugstore options?
Nexxus KERAPHIX uses patented KRT (Keratin Resistance Therapy) with liquid crystal serine amino acids—a technology developed for professional salons. The shampoo delivers 24X stronger hair vs. non-conditioning shampoo, visible from the first wash. This clinical efficacy, combined with elegant packaging and the Keratin Protein + Black Rice scent, positions it as a luxury professional treatment you control at home.
Is this shampoo's KRT technology considered high-end professional-grade hair repair?
Yes. KRT technology reconstructs disulfide bonds from cuticle to cortex—a deep internal repair approach used in high-end salons. Unlike surface-level conditioning, this formula seals cuticle cracks to prevent future damage while rebuilding strength, delivering salon-caliber results in your own bathroom.
Does the large 33.8 fl oz bottle make for an elegant bathroom vanity display?
Absolutely. The substantial, professional-looking bottle with refined branding elevates bathroom aesthetics. The large format signals investment in quality and creates a curated luxury bathroom look—perfect for a master bath or guest bath where guests notice thoughtful, premium products.
Can I gift this shampoo as a luxury hair care product to someone with color-treated hair?
Yes, it's an excellent luxury gift. The premium positioning, visible results (24X stronger hair), and elegant bottle make it feel special. Pairing it with Keraphix Conditioner creates an elevated gift set that shows thoughtfulness toward someone's hair health—ideal for birthdays or self-care gifts.
Is the bond-reconstruction formula noticeably more sophisticated than standard protein shampoos?
Yes. While standard protein shampoos coat the surface, Nexxus KERAPHIX reconstructs the internal structure of damaged hair through liquid crystal amino acids. This targets the root cause of damage rather than masking it—a sophistication level that delivers dramatic, lasting results versus temporary smoothness.
How often should I use Nexxus KERAPHIX Shampoo to see repair results?
Use daily as your regular shampoo for best results. Most users report visible improvements in hair strength and smoothness after the first wash, with cumulative benefits building over 2–4 weeks. Consistent daily use allows KRT technology to continuously rebuild and protect damaged hair.
Can I use Nexxus KERAPHIX Shampoo if I have color-treated or bleached hair?
Yes, it's specifically formulated for color-treated and bleached hair. The KRT technology repairs damage from coloring and bleaching by reconstructing disulfide bonds, while the Damage Shield helps protect your color investment from future chemical and heat damage.
Does this shampoo work well with heat styling tools like blow dryers and flat irons?
Yes. Keraphix boosts elasticity and manageability before heat styling and seals the cuticle to protect against heat damage. When used daily before blow-drying or flat-ironing, the Damage Shield creates a protective barrier that minimizes breakage and frizz during styling.
What's included in the Nexxus KERAPHIX Shampoo bottle, and what do I need to buy separately?
You receive a 33.8 fl oz (or 13.5 fl oz travel size) bottle of Keraphix Shampoo ready to use—no additional setup needed. For a complete damage-repair regimen, you can pair it with Keraphix Conditioner and Treatment, though the shampoo alone delivers significant benefits. No special applicators or tools required.
Is Nexxus KERAPHIX Shampoo safe for all hair types and colors?
Yes. The formula is safe for all hair colors and works on all hair types—blonde, brunette, red, and black hair all benefit from KRT technology. However, it's specifically optimized for damaged, color-treated, or chemically processed hair seeking repair and strength.
Will this shampoo cause buildup or make my hair feel heavy?
No. Keraphix is specifically formulated with a no-buildup design that delivers deep moisture and repair without residue or heaviness. This means you can use it daily without clarifying shampoos or worry about product accumulation weighing your hair down.
What is KRT (Keratin Resistance Therapy) and how is it different from regular keratin treatments?
KRT (Keratin Resistance Therapy) is Nexxus's patented technology using liquid crystal serine amino acids to reconstruct disulfide bonds from the cuticle to the cortex—the internal structure of your hair. Unlike surface-level keratin coatings, KRT rebuilds hair at a molecular level, creating stronger, more resilient strands that resist future damage.
How long does one 33.8 fl oz bottle of Nexxus KERAPHIX Shampoo last with daily use?
At standard daily use (roughly a quarter-sized amount per wash), a 33.8 fl oz bottle typically lasts 2–3 months. This makes it an economical choice for long-term daily hair care, especially compared to buying smaller bottles repeatedly.
Can I use Nexxus KERAPHIX Shampoo if my hair is already healthy, just to prevent future damage?
Yes. While formulated for damaged hair repair, the Damage Shield technology makes it excellent for prevention too. If you heat style frequently, use color treatments, or bleach your hair, using Keraphix daily protects against future damage—making it a proactive choice for maintaining hair health.
Is Nexxus KERAPHIX Shampoo suitable for curly, wavy, or textured hair?
Yes. The repair and moisture benefits work on all hair textures. Curly and textured hair often experiences more dryness and breakage, making KRT technology's bond reconstruction and elasticity-boosting benefits especially valuable for maintaining curl definition and preventing frizz.
