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. 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.

Frequently Asked Questions
Will this shampoo help me maintain my salon color so I can spend less time and money at appointments?
Yes. Nexxus Color Assure is formulated to protect color for up to 40 washes, extending the time between salon visits. The ChromaBond Sealer technology locks color molecules inside your hair's protein matrix, so you can enjoy your salon results longer and invest your time in what matters most to you.
Does the sulfate-free formula mean my colored hair stays healthier during my daily shower routine?
Absolutely. Sulfates are harsh surfactants that strip color molecules from hair. By using 0% sulfates, Nexxus Color Assure cleanses gently while preserving the pigment your stylist applied, keeping your hair healthier and your color more vibrant through every wash.
Can this shampoo actually repair damage from bleach and highlights while protecting color?
Yes. The bond-strengthening citric acid in this formula repairs cuticle damage caused by chemical processing while the ionic sealing complex creates a protective layer around each strand. You get dual benefits—damage repair and color protection—in one step of your routine.
Is the 33.8 oz size worth buying for my daily wellness routine, or should I get the smaller bottle?
The 33.8 oz size is ideal for daily users who want to streamline their routine and reduce repurchasing. At a better cost per ounce, it means fewer trips to restock and more consistent color protection throughout your week. It's the mindful choice for committed color care.
How does this shampoo fit into a low-maintenance hair care ritual for color-treated hair?
Nexxus Color Assure simplifies your routine. One shampoo delivers cleansing, color protection, and damage repair—no need for multiple products. Use it daily in the shower, and you're actively protecting your investment in salon color without extra steps or fuss.
How often should I use Nexxus Color Assure shampoo for best color protection results?
Use 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.
What's the best way to apply this shampoo to get maximum color protection?
Wet 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.
Can I use this shampoo on all hair types, or just color-treated hair?
It'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.
Does this shampoo work with all hair colors, or is it better for certain shades?
Nexxus 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.
What's included in the bottle, and do I need to buy a conditioner separately?
Each 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.
Is there any setup required, or can I use it right out of the box?
No setup required. Simply unscrew the cap and use as you would any shampoo. The bottle is ready to use immediately upon delivery. We recommend starting with your next shower to begin the 40-wash color protection cycle.
Will this shampoo cause any irritation to sensitive scalps or skin?
Nexxus Color Assure is sulfate-free and formulated to be gentle on color-treated hair and scalps. However, if you have a known sensitivity to citric acid, keratin, or other ingredients, review the full ingredient list before use. As with any new hair care product, perform a patch test if you have a sensitive scalp.
Is this shampoo safe to use if I have scalp conditions like dandruff or psoriasis?
The sulfate-free formula is gentler than conventional shampoos, but if you have an active scalp condition, consult your dermatologist 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.
What's the difference between color-safe shampoo and regular shampoo?
Regular 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.
