If you’ve ever dyed your hair and watched that vibrant hue fade too fast, you need to give Nexxus Color Assure Shampoo a whirl. I’ve been there, chasing that salon-fresh glow, and this stuff is a game-changer.
It’s crafted to keep your color popping for weeks, and trust me, it delivers. With a blend of fancy proteins and a sulfate-free formula, it’s like a spa day for your colored locks.
Stick with me as I spill the tea on my experience, the good, the not-so-great, and how to make your hair color last longer than your last Netflix binge.
My Journey With Nexxus Color Assure Shampoo

Picture this: I’d just left the salon with a fiery copper hue that had me feeling like a total rockstar.
My stylist warned me that vibrant shades like this can slip away fast if I didn’t baby my hair.
So, I grabbed Nexxus Color Assure Shampoo and Conditioner, hoping they’d keep my color as bold as my confidence.
Spoiler alert: they mostly did.
The first time I used it, I was hit with this luxurious scent—think high-end salon vibes, not overpowering floral nonsense.
It’s like stepping into a fancy spa without leaving your bathroom.
I lathered up, and the shampoo felt creamy, coating my hair without that squeaky-clean stripping sensation I’ve gotten from cheaper brands.
My hair felt clean but not parched, which was a win since I’ve got naturally wavy strands that can turn into a frizzy mess if I’m not careful.
The conditioner, though?
Oh, it’s the star of the show. It glided on like silk, and as I worked it through my ends, my hair already felt softer. After rinsing, my copper shade looked just as vivid as day one, with a glossy shine that had me flipping my hair in the mirror like I was in a shampoo commercial.
I followed the bottle’s advice—shampoo, condition, rinse—and noticed my color stayed punchy even after a couple of weeks. Usually, I’d see some dulling by then, but not this time.
One thing I’ll say: the shampoo can feel a tad drying if you overdo it. I learned to use just a dime-sized amount for my shoulder-length hair, and that was plenty. The conditioner, on the other hand, I slathered on generously, letting it sit for a minute before rinsing.
My hair felt smooth, tangle-free, and honestly, it smelled so good I caught my partner sniffing my head like a weirdo. By week three, my color was still turning heads, and I was hooked. It’s not perfect—more on that later—but it’s the best I’ve tried for keeping my dye job fresh.
What Makes Nexxus Color Assure Shine?
- Long-Lasting Color Protection

Let’s talk about the big win: this shampoo keeps your color vibrant for ages.
Nexxus claims up to 40 washes, and while I didn’t count every shampoo session like a math nerd, my copper stayed bold for over a month.
That’s huge, especially for reds, which usually fade faster than my patience in traffic.
The sulfate-free formula doesn’t strip your dye, and the ProteinFusion blend—fancy talk for elastin protein and quinoa—seems to lock in the color like a vault.
I noticed less fading compared to other brands I’ve used, and my hair still had that just-dyed glow weeks later.
- Silky, Nourished Hair
You know that feeling when your hair is so soft you can’t stop touching it? That’s what the conditioner does. It’s like a tall glass of water for thirsty, color-treated hair. After every wash, my strands felt smooth and hydrated, not weighed down or greasy.
The shampoo cleans thoroughly without leaving my hair brittle, and together, they make my wavy locks behave better than usual. No frizz, no dryness—just healthy-looking hair that moves like it’s in a breeze, even when I’m stuck inside.
- Salon-Quality Vibes
There’s something about Nexxus that screams “I spent way more at the salon than I did.” The scent, the texture, the way it lathers—it all feels luxe. It’s no surprise, since Nexxus was born in salons and leans on science to back up its claims.
The White Orchid infusion adds a touch of pampering, and I swear it makes my bathroom feel like a high-end spa. If you’re someone who loves that fresh-from-the-stylist vibe, this duo delivers it in spades.
- Gentle on Your Scalp
If your scalp throws a tantrum with harsh shampoos, you’ll like this. Being sulfate- and silicone-free, it’s gentle enough for daily use, though I stick to every other day to keep my color intact.
My scalp never felt itchy or irritated, which is a miracle for someone who’s battled flakes in the past. It cleans without overdoing it, so my oily roots stayed in check without drying out my ends.
The Downsides of Nexxus Color Assure
- Shampoo Can Feel Drying

I’ll keep it real: the shampoo isn’t perfect.
Sometimes, it left my hair feeling a bit coarse during the wash, like it was stripping just a touch too much moisture.
It’s not a dealbreaker, but if you’ve got super dry or curly hair, you might notice it more.
I got around it by using less product and following up with a generous scoop of conditioner, but it’s something to watch.
Pairing it with a different shampoo now and then helped, too.
- Conditioner Might Be Too Heavy for Some
The conditioner is my holy grail, but it’s not for everyone. If your hair is fine or gets oily fast, you might find it a bit heavy. I heard from a friend with thin hair that she had to wash more often because her roots looked greasy by day two.
For me, it was fine since my waves soak up moisture, but if you’re prone to limp locks, go easy on the amount or rinse it out quicker.
- Pricey for Everyday Use
Let’s talk dollars. Nexxus isn’t cheap. A bottle costs more than your average drugstore pick, and if you’re washing a lot, you’ll burn through it faster than you’d like. I stretched mine by alternating with a cheaper shampoo once a week, but it’s still an investment.
For the results, I think it’s worth it—especially for tricky colors like red—but if you’re on a tight budget, it might sting a bit.
Tips For Your Colored Hair
- Wash Smart, Not Often
You want your color to last?
Don’t wash your hair every day. I learned this the hard way after fading a gorgeous auburn in record time. Stick to two or three washes a week, using Nexxus Color Assure when you do. Less washing means less chance for your dye to slip down the drain.
If your roots get oily, a quick blast of dry shampoo is your best friend. I rinse with lukewarm water, too—hot water is like kryptonite for vibrant color.
- Condition Like You Mean It
Conditioner is non-negotiable for colored hair. I leave Nexxus Color Assure Conditioner on for at least two minutes before rinsing to let it work its magic. It’s like giving your hair a big hug after the shampoo’s done its job.
Once a week, I swap in a deep conditioning mask for extra TLC, especially on my ends, which get dry from all the heat styling I can’t quit. Pro tip: don’t skimp on the conditioner, but focus it mid-length to ends to avoid greasy roots.
- Protect from the Elements
Sun, chlorine, and pollution are out to dull your shine. I noticed my color fading faster in summer until I started shielding it. A wide-brimmed hat is my go-to for beach days, and I rinse my hair with fresh water after swimming to get rid of chlorine.
If you’re blow-drying or flat-ironing, use a heat protectant spray—Nexxus has one, but any decent one works. It’s like sunscreen for your hair, keeping that color locked in tight.
- Touch Up with a Glossing Tonic
For an extra boost, I started using Nexxus Color Assure Glossing Tonic on damp hair once a week. It’s like a topcoat for your color, adding shine and making your dye look fresher longer. I smooth it through my ends, avoiding the roots so it doesn’t weigh my hair down.
It’s not mandatory, but it’s a nice treat when my color needs a pick-me-up between salon visits.
- Eat for Healthy Hair
This one surprised me, but what you eat matters. I started adding more protein-rich foods like eggs and salmon to my diet, and my hair’s been stronger and shinier. Biotin supplements helped, too, though check with a doc before popping pills.
Healthy hair holds onto color better, so don’t sleep on your diet. It’s not just about what you put on your hair—it’s what’s going on inside, too.
How Nexxus Color Assure Shampoo Stacks Up Against Other Brands?
I’ve tried my fair share of shampoos to keep my colored hair looking fresh, and Nexxus Color Assure has some stiff competition. To give you the full picture, I’m putting it head-to-head with three other popular picks: Redken Color Extend Magnetics Shampoo, L’Oreal Paris Elvive Hyaluron Plump Hydrating Shampoo, and Pureology Hydrate Shampoo.
Each has its strengths, but let’s see how they measure up in terms of color protection, hair feel, scent, and overall vibe. I’m breaking it down so you can decide what’s worth your cash.
- Nexxus Color Assure Vs. Redken Color Extend Magnetics

When I first used Redken Color Extend Magnetics, I was impressed by its no-nonsense approach.
It’s like the science nerd of shampoos—packed with amino acids and ceramides that make your hair feel fortified.
My copper shade stayed vibrant for weeks, almost neck-and-neck with Nexxus, which claims up to 40 washes of color protection.
But here’s where they part ways: Redken feels more clinical.
The lather is decent, but it lacks the creamy, indulgent texture of Nexxus that makes me feel like I’m at a salon. Scent-wise, Redken’s clean but forgettable, while Nexxus’s White Orchid aroma lingers like a luxe perfume.
Redken’s great for damaged hair—my strands felt stronger after a month—but it left my waves a tad flat compared to Nexxus’s bouncy shine. Price is another kicker: Redken’s pricier for smaller bottles, so Nexxus wins for value and that pampered vibe, though Redken’s a close second if you need serious repair.
- Nexxus Color Assure Vs. L’Oreal Paris Elvive Hyaluron Plump Hydrating

L’Oreal’s Elvive Hyaluron Plump Hydrating Shampoo is the budget-friendly contender I keep in my shower for variety.
It’s not marketed strictly for color-treated hair, but it’s sulfate-free and promises hydration, so I gave it a shot.
The hyaluronic acid makes my hair feel plump and soft, especially on humid days when my waves need taming.
Compared to Nexxus, though, it falls short on color protection.
My copper started dulling by week two, while Nexxus kept it fiery well into week four.
L’Oreal’s lather is airy and fun, but it doesn’t coat my hair with the same nourishing heft as Nexxus’s ProteinFusion blend. The scent is a bright, fruity burst—nice, but not as sophisticated as Nexxus’s spa-like fragrance.
For the price, L’Oreal’s a steal, and it’s great if your hair’s fine or oily since it’s lighter. But if vibrant color is your goal, Nexxus runs circles around it, delivering longer-lasting shine and a richer feel.
- Nexxus Color Assure Vs. Pureology Hydrate

Pureology Hydrate Shampoo is the fancy-pants option that had me swooning at first.
It’s vegan, sulfate-free, and feels like liquid silk, with jojoba and green tea that make my hair insanely soft.
Color-wise, it’s a champ—my dye stayed bold for weeks, nearly matching Nexxus’s staying power.
But here’s the rub: Pureology’s hydration is almost too intense for my wavy hair.
By day two, my roots felt a bit heavy, something I never get with Nexxus’s balanced formula. The scent is herbal and calming, but I prefer Nexxus’s White Orchid for its upscale edge.
Pureology’s lather is dreamy, and my hair felt nourished from root to tip, but the price tag made me wince—think Nexxus on a bad day, then add a few bucks. If your hair’s parched, Pureology’s a godsend, but Nexxus gives me the same color protection and softness without the extra cost or occasional greasiness. It’s a tight race, but Nexxus fits my vibe better for everyday use.
Each of these shampoos has its perks, but Nexxus Color Assure holds its own by blending color protection, luxe texture, and a price that doesn’t make me rethink my life choices.
Redken’s ideal for damaged locks, L’Oreal’s a budget win, and Pureology’s a hydration hero, but Nexxus gives me that salon-fresh glow without overcomplicating things. Your hair’s unique, so it’s about finding what clicks for you.
Frequently Asked Questions (FAQ)
Nexxus has a few color-safe options, but the Color Assure Shampoo is the star for dyed hair. It’s sulfate-free and designed to keep your color vibrant for up to 40 washes. Their Therappe Shampoo is gentler but not specifically for color-treated hair, so stick with Color Assure if you’re rocking a fresh dye job. Pair it with the matching conditioner for the best results.
Yes, but it depends on the formula. Color-safe shampoos like Nexxus Color Assure skip harsh sulfates that strip dye, so your color fades slower. I noticed my copper stayed bold weeks longer than with regular shampoo. They’re not magic—water and heat still play a role—but a good one makes a real difference, especially for reds or pastels.
Nexxus calls itself salon-crafted, and I’d say it lives up to the hype. Born in salons and backed by science, it feels like something your stylist would use. The ProteinFusion blend and fancy ingredients like White Orchid give it that pro-level edge. It’s not just marketing fluff—my hair feels pampered and my color lasts like I just left the chair.
It’s simple. Wet your hair, then massage a small amount of Color Assure Shampoo into your scalp and strands. Rinse thoroughly. Follow with the Conditioner, working it through from mid-lengths to ends. Let it sit for a minute or two, then rinse. For extra shine, I sometimes use their Glossing Tonic on damp hair. Use it a few times a week to keep your color popping.
