Nexxus Color Assure Shampoo and Conditioner Review: Quiet Luxury For Color-Treated Hair

Yes, this system is designed to help maintain color vibrancy over many washes, and in our testing it did a strong job of preserving depth and shine on most brunettes, blondes, and softer reds. You still need to pair it with cool water and gentle styling to truly maximize that longevity.

You’ll usually feel a difference in softness and manageability after the first wash—hair tends to comb out more easily and look smoother once dry. The color-protection benefits become clearer over several weeks as you notice less dullness and slower fading between salon visits.

It performs very well on both in our experience. The conditioner, in particular, lays down a smooth, light-reflective finish that tames surface frizz and boosts shine, especially on wavy and thick hair. If you air-dry, expect a sleeker, more polished texture than with many basic color-safe lines.

This duo is more about preserving color and improving feel than repairing extreme damage. The proteins and oils help hair look stronger and smoother, but if your hair is very compromised or breaking, you’ll want to layer in a dedicated repair or bond-building treatment alongside it.

It’s formulated for regular, even daily use. In our testing, most color-treated hair types did well washing two to three times a week with this system. If your scalp is sensitive or easily overloaded, you might alternate with a gentle clarifying or scalp-focused shampoo.

Yes, the shampoo is sulfate-free, relying on gentler cleansers like Coco-Betaine and Sodium Cocoyl Isethionate. That means it’s less likely to strip dye molecules and natural oils, which is why it tends to keep color looking richer and hair feeling less parched than traditional sulfate shampoos.

The conditioner does contain silicones, including dimethicone and amodimethicone, along with rich fatty alcohols and oils. These create slip, shine, and that smooth, detangled feel. Most color-treated hair loves this, but if you’re prone to buildup or follow a strict silicone-free routine, it’s something to consider.

The formulas include fragrance, dyes, and preservatives such as DMDM Hydantoin and isothiazolinones, which can be problematic for very reactive skin. While many people use Color Assure comfortably, some of our testers did experience dryness or itch, so patch testing or starting slowly is wise if you know you’re sensitive.

Yes, it’s rich in proteins like Hydrolyzed Elastin, Keratin, and Wheat Protein. These can help strengthen and support elasticity in damaged hair, but on low-porosity or protein-sensitive hair, overuse can sometimes lead to stiffness or dryness. If your hair starts to feel brittle, alternate with a more moisture-focused line.

There are no special warnings listed for pregnancy or breastfeeding, and it’s a standard cosmetic formula. That said, because it contains fragrance and certain preservatives, we always advise discussing any concerns with your healthcare provider if you’re being especially cautious about personal care products.

Focus the shampoo at the roots, add plenty of water to build a gentle lather, and rinse thoroughly with lukewarm (not hot) water. Then apply conditioner from mid-lengths to ends, leave it on for a few minutes, and rinse well. Avoid scrubbing or over-washing, which can accelerate fading regardless of product.

For shoulder-length hair, we found one to two pumps of shampoo and a similar amount of conditioner sufficient when hair was fully saturated with water. Longer or thicker hair may need more, but if you’re using handfuls, focus on better distribution and emulsifying the product with water rather than simply increasing quantity.

You can, and it will still cleanse and condition, but you won’t be tapping into its core strength, which is color preservation. Natural, untreated hair might be better served by a line tailored to its specific needs—volume, moisture, or repair—unless you simply love the feel and fragrance of this formula.

You don’t need to avoid styling products, but very heavy creams, oils, or sprays can contribute to buildup, especially since this system already leans conditioning. If roots start feeling coated or greasy quickly, consider lightening up on leave-ins or adding an occasional clarifying wash to reset.

Yes, and we actually enjoyed it that way. Mixing a small amount of conditioner with water in a spray bottle created a lovely, lightweight detangling mist for non-wash days. Just keep it to mid-lengths and ends, and avoid the scalp to prevent unnecessary heaviness.

It can work, but it requires a light hand. Fine or thin hair types in our testing did best using a small amount of shampoo, keeping conditioner strictly on the ends, and rinsing very thoroughly. If your hair collapses easily or gets oily fast, you may prefer a more weightless color-care line.

This is where Color Assure really shines. Medium to thick, wavy, and curly textures loved the extra slip and moisture, with less frizz and easier detangling. Some curl patterns loosened slightly with repeated use due to the smoothing effect, so if you prize maximum volume and spring, you may want to alternate with a curl-specific formula.

It helped our bleached and highlighted testers feel softer and look less frazzled, thanks to the protein and oil blend. However, if you’re dealing with active breakage, consider this your everyday maintenance step and add a more intensive repair mask or bond-builder weekly for deeper structural support.

For some, it actually extended time between washes; for others, the richer conditioning agents contributed to oilier roots by day two. If you’re in the latter camp, keep conditioner away from the scalp, rinse thoroughly, and consider rotating in a balancing or clarifying shampoo once a week.

Because it contains fragrance, dyes, and certain preservatives, this wouldn’t be our first choice for extremely reactive or eczema-prone scalps. Some sensitive testers tolerated it, but others experienced itch or dryness. In those cases, a fragrance-free, dermatologically tested line is usually a safer starting point.

The sulfate-free, gel-like texture behaves differently from traditional shampoos. It needs plenty of water and a bit of emulsifying in your hands to spread well. If you apply it too thickly or don’t rinse long enough, it can feel slippery or leave a slight film, especially at the roots.

This was a recurring frustration in our testing. If a pump refuses to pop up or breaks, the most practical workaround is decanting into another pump bottle or reusing a functioning pump from a previous product. It’s inelegant, but it preserves the formula itself, which is typically unaffected.

In humid environments, the smoothing, silicone-rich conditioner helps keep frizz in check, though oil-prone scalps may need more frequent washing. In very dry climates or heated indoor air, the extra moisture and slip are a blessing for parched ends. The main adjustment is wash frequency and how much conditioner you use.

No—this is a maintenance system, not a coloring product. It will help your existing color look fresher for longer but won’t address grey coverage or visible roots. For that, you’ll still need your regular color appointments or a dedicated root-touch-up product.

From our perspective, it sits in a sweet spot. The formulas feel and perform more like salon products than typical mass-market options, yet the cost per use—especially given the generous bottle size—is friendlier than many professional lines. If it suits your hair, it’s a savvy way to get a prestige wash experience without the steepest price tag.

For most of our testers washing two to three times a week, the large bottles comfortably stretched over a couple of months or more. Exact timing depends on hair length and how liberally you pump, but this isn’t a duo you’ll burn through in a few weeks.

The fragrance is noticeable in the shower and as hair dries, but on most of us it settled into a soft, clean veil rather than a strong cloud. You’ll catch whiffs when you move, but it won’t typically compete with your fragrance or feel overpowering in close quarters.

Because the bottles are large and the pumps can be temperamental, we’d keep them as your at-home staples. For travel, decant into smaller, leak-proof containers—your hair will appreciate the continuity of care without the bulk or risk of a pump mishap in your luggage.

Absolutely. Several men on our testing panel used it on their colored or highlighted hair and appreciated the softness and clean, salon-like scent. The formula isn’t gendered; it’s simply tailored to the needs of color-treated strands, regardless of who’s in the shower.

Yes, and for some hair types that’s ideal. Many of us alternated it with a clarifying, volumizing, or bond-repair system depending on what our hair needed that week. As long as you’re not over-washing or overloading with protein, mixing and matching can give you a more customized routine.
