Top 10 Hair Straightening Shampoos That Keep Your Locks Smooth & Shiny

You know those mornings when your hair just refuses to cooperate? This fixes that. UNITE’s Lazer Straight is one of those rare shampoos that earns the hype—it cleans, smooths, and makes your hair behave before you’ve even reached for the dryer.

People with curly or frizzy hair can’t stop talking about it. One even said it made their hair “so straight I didn’t bother flat-ironing,” which… honestly, respect.

The secret’s in the formula. Amino acids that soften texture, coconut-based cleansers that lift away buildup without roughing things up, and plant proteins that help seal down the cuticle so it stays sleek. There’s also a hit of heat protectants, which is great if your idea of styling involves, well, actual heat.

City life is tough on hair—smog, subway air, too much sun, you name it. Bel Air gets it. It’s the kind of shampoo that acts like armor without feeling heavy or fussy. R+Co built it to handle all the stuff your strands deal with every day: pollution, UV, humidity, and whatever else comes with the skyline.

Inside, there’s artichoke extract (your cuticle’s new best friend) to help shield against environmental stress, broccoli seed oil for that subtle, natural shine, and vitamin B5 to keep things hydrated and strong. Honestly, it’s one of those formulas that doesn’t scream for attention — it just works quietly in the background, doing the most.

It’s sulfate-free, cruelty-free, and feels just fancy enough to make your shower routine better. Low effort, high reward. Once you try it, good luck going back to anything else.

You’d think “oil-based shampoo” would be heavy. Not here. Bumble and Bumble got it right with six lightweight oils that hydrate without flattening fine hair.

Coconut, argan, and macadamia oils soften and add shine without greasy residue. There’s also sweet almond, grapeseed, and safflower oils, which help repair split ends and protect against heat and UV damage, so your hair feels healthier every time you wash.

People rave about how it tames dryness without killing volume. Basically, it’s smooth hair with bounce. The perfect combo. It’s professional-grade but low-effort, which explains its cult following. The kind of shampoo stylists actually take home from the salon for themselves.

If you color your hair, you already know the trade-off—soft and shiny or vibrant and long-lasting. Pureology basically said, “Why not both?” and built this shampoo to do it. It smooths, protects, and somehow keeps your color looking like it was done yesterday, even after a week of washes.

Inside, you’ll find camellia oil and shea butter, which team up to soften the cuticle and lock in hydration without stripping pigment. There’s also Pureology’s exclusive AntiFade Complex, packed with sunflower seed extract and vitamin E to fight oxidation—the sneaky culprit behind dull, faded tones.

It’s one of those formulas that feels instantly different—creamy, rich, but still light enough to rinse clean. People who’ve sworn off sulfate-free shampoos for being too “meh” usually come back around after this one. Basically, if you spend money on highlights or balayage and want that glossy, smooth finish to last longer than your patience, this is your shampoo.

There’s something about Italian beauty products. They don’t scream luxury; they kind of whisper it. Davines LOVE is that kind of shampoo. It’s simple, a little artsy, and makes your hair feel calmer after one wash. Like it finally took a breath.

The magic comes from minuta olive extract grown on small Sicilian farms. It feeds the hair instead of coating it, which is why it feels soft but still real, not slippery. Then you’ve got rice protein and these gentle, plant-based cleansers doing quiet work in the background, keeping the texture smooth and healthy without that “over-conditioned” feeling.

It doesn’t smell fancy; it smells clean. Warm, like fresh laundry hanging in the sun. And it’s sustainable, which honestly just feels right for a brand like this.

This one’s kind of the overachiever of the bunch. It’s a 10 is famous for being the product stylists secretly keep for themselves, and honestly, after a few washes, you get why.

There’s keratin in here, obviously—the thing that smooths out those rough ends and helps your hair remember what shine feels like. Then you’ve got panthenol and a little sunflower extract, both quietly working to keep moisture where it belongs. The result is hair that feels stronger, softer, and just better behaved.

It lathers up rich but rinses out clean, leaving your hair shiny, soft, and obedient. No residue, no heaviness. Just that smooth bounce you’ve been trying to get from a blowout.

If you’ve ever wanted one bottle that makes your whole routine simpler, this is the one you grab and thank yourself for later.

If you’ve got thick hair, you know the drill: heavy, stubborn, a little frizz that never quite listens. OGX’s Brazilian Keratin Therapy gets it. It isn't fancy or minimalist—it’s just really good, and manages to make your hair behave. Softer. Smoother. Easier. 

Inside, there’s keratin protein doing the smoothing work, and coconut oil adding that hit of hydration thick strands are always begging for. You’ll also find avocado oil and cocoa butter, both rich enough to calm puffiness without flattening your natural volume. It doesn’t coat or weigh down, it just makes your hair easier to deal with.

And the smell—warm, creamy, and lightly tropical. Like a mini vacation in your shower.

You know when your stylist tells you to stop buying cheap shampoo and you roll your eyes, then finally cave and realize they were right? Kérastase Discipline Bain Fluidealiste is basically salon hair in a bottle. It smooths, softens, and makes your blow-dryer’s job about half as hard.

The secret is its morpho-keratin complex, which helps rebuild the hair’s outer layer so it stays sleek and reflective instead of puffy or dry. There’s also lipid compounds and amino acids mixed in—they work together to strengthen weak spots and give that silky, elastic feel you only get from a professional treatment.

It’s rich, but not heavy. Creamy, but still weightless. You don’t need much either. A small pump turns into a dense, soft lather that smells like the best part of a salon visit. You rinse it out and your hair feels instantly smoother and shinier.

The results hang around, too. It's one of those bottles that earns a spot on your shower shelf and stays there.

If your hair’s been through it—bleach, heat, humidity, all of it—this shampoo is a vacation and rehab in one. It’s rich, it’s indulgent, and it actually makes damaged hair feel healthy again.

The base is their Brazilian Patua oil, which restores elasticity and smooths the hair’s surface so it feels soft instead of fried. There’s also Brazil nut oil for shine and strength, and a touch of coconut oil to seal in moisture and keep frizz under control. Together, they take your hair from “stressed out” to “I wake up like this.”

It lathers thick and creamy, smells like warm sunshine and caramel (that signature Sol de Janeiro scent everyone recognizes), and leaves your hair smooth enough that you might skip the flat iron. The shine builds over time too. Like each wash erases a little bit of the damage.

There's something satisfying about a product that just does what it says. No gimmicks, no promises of "salon transformation." Just clean hair that feels smoother than it did yesterday. TRESemmé's Keratin Smooth Blowout Shampoo is that. Unpretentious, and way better than it has any right to be for so little money.

It's built with keratin and marula oil, which sounds simple, but that combo's doing the heavy lifting. The keratin helps align cuticles for smoother strands, while the marula adds a hit of moisture and shine so your hair doesn't feel dry. It's glossy without that weighed-down, slippery feel some "smoothing" shampoos have.

You feel the difference right away. And the bottle lasts forever, which makes it feel like even more of a win. It's not trying to be luxury. It's just solid. Reliable. The one you keep coming back to even after you've flirted with fancier stuff.
