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. Hair color fading is tied to the integrity of your hair’s protein structure. Every exposure to physical, thermal, or chemical stress weakens keratin structures, making hair more vulnerable over time. Color treatments—like bleach, highlights, and dyes—with high pH can raise the cuticle and expose the inner cortex, leaving hair vulnerable to breakage and tonal irregularity. Over time, this damage compromises optical clarity and allows color molecules to diffuse when hair is exposed to water, accelerating fade. As a result, colored hair can appear dull, flat, and lifeless. Color Assure, our vibrancy and anti-fade collection, is powered by CHROMABOND SEALER technology with citric acid to lock color molecules inside the protein matrix and seal the cuticle barrier. This advanced shampoo for color treated hair and conditioner for colored hair system combines citric acid bond strengtheners with ionic sealing technology to repair color-induced damage and create a smooth, reflective surface—so your color stays vibrant, multidimensional, and radiant for up to 40 washes. Nexxus, the protein science behind powerful hair since 1979.\u003cbr\u003e\u003cbr\u003eItems Details\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eFeatures \u0026amp; Specs\u003cbr\u003eItem Form: Liquid\u003cbr\u003eHair Type: Color Treated\u003cbr\u003eScent Name: Fragranced\u003cbr\u003eOther Special Features of the Product: with ProteinFusion\u003cbr\u003eProduct Benefits: Color Care, Color Protection, Nourishing, Shining\u003cbr\u003eSuitable Hair Color: All Hair Colors\u003c\/section\u003e\u003csection class=\"geo-faq\"\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat makes ChromaBond Sealer technology a premium feature compared to standard color shampoos?\u003c\/h3\u003e\n\u003cp\u003eChromaBond Sealer is a proprietary 3.3% technology with citric acid that locks color molecules inside a protein matrix at the molecular level. This science-backed approach is more sophisticated than basic color-safe formulas—it's the kind of advanced technology you'd expect in high-end salon products.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eDoes the ProteinFusion technology justify the premium price for treating highlighted or bleached hair?\u003c\/h3\u003e\n\u003cp\u003eCompletely. ProteinFusion targets keratin repair at the structural level, addressing damage from the inside out. Combined with ionic sealing and citric acid bond-strengthening, this multi-layer repair system delivers the kind of comprehensive restoration typically found in luxury salon lines, not drugstore alternatives.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eIs the ionic sealing complex what makes this shampoo feel like a salon-quality product?\u003c\/h3\u003e\n\u003cp\u003eYes. The ionic sealing complex creates a hydrophobic protective layer around each strand, the same technology used in premium salon formulations. This delivers that high-end salon feel and results you're paying for—visible shine, softness, and color vibrancy that commands attention.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhy is the larger 33.8 oz size considered the luxury choice for color maintenance?\u003c\/h3\u003e\n\u003cp\u003eThe larger size reflects a commitment to quality and consistency. Premium buyers appreciate the convenience of fewer repurchases, the cost efficiency of bulk sizing, and the assurance that they can maintain their salon color ritual without interruption—hallmarks of luxury grooming.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eDoes 94% user validation of color protection mean this is truly effective, or is that marketing?\u003c\/h3\u003e\n\u003cp\u003eThat's consumer-validated efficacy from a real home-use test—not a lab claim. Ninety-four percent of actual users confirmed color protection, making this one of the most substantiated color shampoos available. For luxury buyers who value transparency, this is the kind of proof that justifies premium pricing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eHow often should I use Nexxus Color Assure shampoo for best color protection results?\u003c\/h3\u003e\n\u003cp\u003eUse it as your daily shampoo. The formula is gentle enough for everyday cleansing while continuously protecting and repairing color-treated hair. For best results, use it every time you wash to maintain the color-locking benefits of the ChromaBond Sealer technology throughout the 40-wash protection window.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat's the best way to apply this shampoo to get maximum color protection?\u003c\/h3\u003e\n\u003cp\u003eWet your hair thoroughly, apply a quarter-sized amount to your scalp and roots, massage gently for 1–2 minutes to activate the cleansing and sealing technology, then rinse completely. For color-treated lengths and ends, apply a small amount and let it sit for 30 seconds before rinsing to maximize the citric acid bond-strengthening effect.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eCan I use this shampoo on all hair types, or just color-treated hair?\u003c\/h3\u003e\n\u003cp\u003eIt's specifically formulated for color-treated, highlighted, and bleached hair. While the sulfate-free formula is gentle enough for any hair type, the color protection benefits and damage-repair technology are optimized for chemically processed hair. If you have untreated hair, a general sulfate-free shampoo may be more cost-effective.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eDoes this shampoo work with all hair colors, or is it better for certain shades?\u003c\/h3\u003e\n\u003cp\u003eNexxus Color Assure protects all hair colors—blondes, brunettes, reds, and everything in between. The ChromaBond Sealer technology locks color molecules regardless of shade. The 40-wash protection window applies equally across all color types, so you'll see consistent results whether you have highlights, balayage, or solid color.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat's included in the bottle, and do I need to buy a conditioner separately?\u003c\/h3\u003e\n\u003cp\u003eEach bottle contains 13.5 oz or 33.8 oz of Nexxus Color Assure Shampoo. A conditioner is not included in this product. For best results with color protection, we recommend pairing it with a color-safe conditioner, though the shampoo's ProteinFusion technology does provide some conditioning benefits on its own.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eIs there any setup required, or can I use it right out of the box?\u003c\/h3\u003e\n\u003cp\u003eNo setup required.

However, if you have a known sensitivity to citric acid, keratin, or other ingredients, review the full ingredient list before use.

While the formula is color-safe and damage-repairing, it is not medicated and may not address specific scalp health concerns. A dermatologist can recommend the best option for your situation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat's the difference between color-safe shampoo and regular shampoo?\u003c\/h3\u003e\n\u003cp\u003eRegular shampoos typically contain sulfates, which are harsh surfactants that strip color molecules from hair, causing fade. Color-safe shampoos like Nexxus Color Assure are sulfate-free and use gentler cleansing agents. Additionally, this formula includes ChromaBond Sealer technology and citric acid to actively lock in and protect color, rather than just avoiding damage.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Knacklos","offers":[{"title":"Fragranced - 13.5 Fl Oz (Pack of 1)","offer_id":43560945516634,"sku":"XI4B000TGA2TE","price":130.0,"currency_code":"USD","in_stock":false},{"title":"Fragranced - 33.8 Fl Oz (Pack of 1)","offer_id":43560945549402,"sku":"VFIB001EO5WYU","price":29.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/7969\/9034\/files\/3-3-chromabond-sealer-technology-with-citric-acid-to-lock-co.jpg?v=1782512792","url":"https:\/\/knacklos.myshopify.com\/products\/nexxus-color-assure-shampoo-premium-chromabond-sealer-technology-for-salon-grade-vibrancy","provider":"Knacklos","version":"1.0","type":"link"}
