Nexxus Color Assure Shampoo and Conditioner for Color-Treate

The Verdict

Is Nexxus Color Assure worth your money, or is it just another pretty bottle promising color protection? With 225 ratings averaging 4.5 stars, this system has a loyal following. But here’s what the reviews don’t tell you upfront: this is a protein-forward formula, not a color-depositing one. That distinction matters.

What’s Actually in the Bottles

You’re getting two 13.5-ounce bottles — shampoo and conditioner — built around Nexxus’s signature Proteinfusion blend. That’s keratin, elastin, and amino acids designed to rebuild the hair shaft from within. The shampoo is sulfate-free, which is non-negotiable for color-treated hair. The conditioner is thick, almost luxurious, and spreads easily through wet hair.

The packaging is functional and sturdy — flip-top caps that won’t crack after a month of shower use. No pump, which some users find annoying, but the bottles stand upright reliably.

Real-World Performance

Here’s where this system earns its keep. Multiple reviewers with salon-colored hair report their color lasting significantly longer than with drugstore alternatives. One reviewer noted, “My balayage usually fades by week five. I’m at week eight and still getting compliments.” That’s the color-protection story delivering.

But the protein angle is the sleeper benefit. The Proteinfusion blend genuinely strengthens hair. Several reviewers with fine, brittle, color-damaged hair described noticeable improvement in elasticity and reduced breakage within a month of daily use. This isn’t just color protection — it’s damage repair disguised as a color-care line.

The lather is moderate, not the thick foam you get from sulfate-heavy shampoos. That’s expected and fine. But if you use heavy oils, sea salt sprays, or dry shampoo, you’ll likely need a double cleanse. Budget for that.

What Buyers Keep Praising

• “Best shampoo I’ve used on my highlighted hair. No fading, no brassiness.”
• “The conditioner alone is worth it. My hair feels like I just left the salon.”
• “I have 4C hair and this doesn’t strip my curls or leave them crispy.”

The detangling power of the conditioner gets consistent shout-outs across hair types — from fine and straight to thick and coily.

Where It Falls Short

The fragrance is the most common complaint. It’s a strong, classic salon-type scent that lingers. Some love it; others find it overwhelming. If you’re sensitive to fragrance, this might not be your pick.

The price point also sits above drugstore staples. You’re paying for salon-quality results, but it’s not cheap. And if your primary concern is just maintaining color with zero damage concerns, simpler formulas will do the job for less.

Who Should Buy This

• Color-treated hair with damage: If you’ve bleached, highlighted, or chemically processed your hair, this is a strong choice.
• Thick or curly hair: The conditioner’s slip makes detangling manageable.
• People who want one system that does double duty: Color protection plus strengthening.

Skip it if you’re on a tight budget, prefer fragrance-free products, or have virgin hair with no color or damage concerns.

FAQ

Q: Is this safe for keratin-treated or Brazilian blowout hair? A: Yes. The sulfate-free formula won’t strip keratin treatments. The added proteins can actually support the treatment’s longevity.

Q: How often should I use it? A: Daily use is fine for most hair types. If your hair is fine, every other day works better to avoid protein buildup. Alternate with a clarifying shampoo once a month.

Q: Does it actually prevent color fading, or is that marketing? A: The sulfate-free formula prevents the stripping that causes rapid fading. It won’t stop all fading — nothing does — but reviewers consistently report extended color life.

The Verdict

Buy it if you want salon-level color protection with genuine strengthening benefits and don’t mind paying more for quality.

Skip it if the fragrance bothers you, you have very fine hair that’s easily weighed down, or you’re looking for a budget option.

Rating: 4.6/5 — The Nexxus Color Assure system delivers on its promises with real strengthening benefits. Deducting half a star for the polarizing fragrance and the higher price point. This is a solid investment for color-treated hair that needs more than just surface protection.
