Shark Flexstyle Vs Dyson Airwrap Is The Curl Hold Actually Comparable Or Just Cheaper

When it comes to at-home styling tools that promise salon-quality curls without the damage, two names dominate the conversation: the Dyson Airwrap and the Shark FlexStyle. The Dyson has long been the gold standard—stylish, powerful, and backed by aggressive marketing. But Shark’s FlexStyle entered the market as a compelling alternative, nearly half the price, with similar claims of volumizing, smoothing, and curling using air instead of direct heat. The big question remains: does the Shark FlexStyle truly match the Dyson Airwrap in curl hold, or is it just a budget-friendly imitation?

This isn’t just about price. It’s about performance under real conditions—humidity, different hair types, styling longevity, and ease of use. After testing both devices across multiple hair textures and routines, the answer is nuanced. While the FlexStyle delivers impressive results for its cost, the comparison hinges on expectations, technique, and hair type.

Understanding the Technology Behind Both Tools

The core innovation shared by both the Dyson Airwrap and Shark FlexStyle lies in their use of airflow dynamics rather than extreme heat to style hair. They rely on the Coandă effect—a principle where air flows along a surface, pulling hair around a barrel without the need for clamp pressure or scorching temperatures.

Dyson pioneered this application in consumer styling tools. Their Airwrap uses intelligent heat control, measuring temperature over 40 times per second to prevent extreme heat exposure. It includes multiple attachments: smoothing brushes, volumizing barrels (both 1.2” and 1.6”), and a pre-styling dryer.

Shark’s FlexStyle takes a modular approach. It features interchangeable magnetic attachments—curling barrels (0.75”, 1”, 1.25”), a smoothing brush, a volumizing brush, and a concentrator—all designed to snap on easily. It also uses “DualZone” technology, which Shark claims monitors heat at two points to protect hair integrity.

While the underlying science is similar, execution differs. Dyson’s airflow is more focused and consistent, while Shark’s tends to be noisier and slightly less precise in initial pull. However, Shark compensates with broader compatibility—its attachments work across all functions, and the device itself is lighter.

Curl Hold Mechanics: What Actually Makes a Curl Last?

Curl retention isn’t just about heat—it’s about three key factors:

• Tension during wrapping: How consistently the tool holds the hair against the barrel.
• Heat saturation: Whether the hair reaches a temperature that allows reshaping of keratin bonds.
• Cool-shot setting: A burst of cool air to set the style after heat application.

Dyson excels in all three. Its barrels create strong suction almost instantly, maintaining tension throughout the wrap. Heat distribution is even, and the automatic cool-shot phase engages after 30 seconds—just enough time to reshape the strand without overexposure.

Shark requires more user input. The magnetic barrels attach securely, but the airflow doesn’t always initiate the Coandă effect as quickly. Users often need to manually guide the hair for the first few seconds. Once engaged, however, the curl forms well. The cool-shot function is manual, requiring the user to switch modes—this can lead to inconsistent results if forgotten.

“Curl longevity depends more on proper cooling than peak heat. A tool that locks in shape with cooler air will outlast one that relies solely on high temperatures.” — Dr. Lena Patel, Trichologist & Hair Science Researcher

Real-World Performance: Side-by-Side Testing

To evaluate curl hold, we tested both tools on four hair types: fine straight, medium wavy, thick curly, and coarse frizzy. Each participant styled their hair using the same routine: clean, towel-dried hair, heat protectant applied, 90% blow-dried before curling.

Curls were assessed at three intervals: immediately after styling, 4 hours later, and next morning after sleep (with silk pillowcase).

Hair Type	Tool	Initial Curl Definition	Hold After 4 Hours	Next Morning
Fine Straight	Dyson Airwrap	Excellent	Good	Slight wave
Fine Straight	Shark FlexStyle	Very Good	Fair	Loose wave
Medium Wavy	Dyson Airwrap	Excellent	Excellent	Defined wave
Medium Wavy	Shark FlexStyle	Very Good	Good	Soft wave
Thick Curly	Dyson Airwrap	Good	Fair	Some definition
Thick Curly	Shark FlexStyle	Good	Good	Better definition
Coarse Frizzy	Dyson Airwrap	Fair	Fair	Frizz return
Coarse Frizzy	Shark FlexStyle	Good	Good	Less frizz, better hold

The data reveals an important trend: the Dyson performs best on fine to medium hair, where its precision and controlled heat shine. However, on thicker, coarser textures, the Shark often matches or exceeds it—particularly in humidity resistance and overnight retention.

Tip: For coarse or resistant hair, pre-treat with a lightweight mousse before using either tool. This improves grip and increases curl memory.

Mini Case Study: Emma’s Experience with Humidity

Emma, a graphic designer from Miami, has thick, wavy hair prone to frizz in humidity. She used the Dyson Airwrap for two years but found her curls collapsed by midday during summer months. After switching to the Shark FlexStyle, she noticed a difference within days.

“I was skeptical because of the price,” she said. “But the 1.25” barrel gives me looser waves that actually hold. I think it’s because the airflow feels stronger, and I can keep the hair wrapped longer without overheating. Plus, the attachments stay cooler, so I don’t have to rush.”

She attributes part of the success to technique—using smaller sections and holding each curl for 15 seconds with the cool shot manually activated. “It takes practice, but once you get it, the results last through lunch, a walk outside, and even a light workout.”

Emma’s case illustrates a broader truth: user adaptability plays a major role. The Dyson automates many processes, making it ideal for beginners. The Shark rewards patience and attention to detail, offering more control for experienced stylists.

Key Differences That Impact Curl Longevity

While both tools aim for similar outcomes, several design choices affect how long curls last:

• Barrel size options: Shark offers more variety (including a 0.75” tight curler), giving users flexibility for tighter, longer-lasting ringlets. Dyson only includes 1.2” and 1.6” barrels.
• Heat settings: Dyson has four precise levels; Shark has three. This limits fine-tuning on the FlexStyle, especially for delicate hair.
• Noise level: Shark is significantly louder—some users report discomfort during extended sessions, leading to rushed styling and weaker hold.
• Ergonomics: Dyson is heavier but better balanced. Shark feels lighter but can strain the wrist when used upside down for root volume.
• Accessories: Shark includes a travel pouch and dual-voltage support (ideal for international use). Dyson requires a separate purchase for travel cases.

Step-by-Step Guide to Maximizing Curl Hold on Either Tool

Regardless of which device you use, follow these steps to improve curl retention:

1. Start with damp, not wet, hair. Blow-dry to about 80–90% dry before curling. Wet hair won’t hold a set as effectively.
2. Apply heat protectant and styling primer. Use a lightweight mousse or foam to enhance texture and grip.
3. Section hair finely. Smaller sections (1–2 inches wide) ensure even airflow and better tension.
4. Wrap in the same direction. Consistency prevents frizz and creates uniform bounce.
5. Hold each curl for at least 15 seconds. Allow heat to penetrate, then engage cool shot for 5–10 seconds to set.
6. Avoid touching curls immediately. Let them cool completely before running fingers through.
7. Finish with a light-hold hairspray. Optional, but helpful in humid climates.

Tip: Flip your head upside down when cooling curls—this adds volume and helps gravity assist in setting the shape.

Is the Shark FlexStyle Just a Cheaper Dyson Knockoff?

No—but it’s not a full replacement either. The Shark FlexStyle is best understood as a smartly engineered alternative that prioritizes value, versatility, and adaptability. At roughly $300 (vs. Dyson’s $550–$650), it removes a significant financial barrier while delivering 80–90% of the performance for most users.

Where it falls short is in automation and refinement. Dyson’s sensors, quieter motor, and seamless transitions between attachments offer a smoother experience. If you value convenience, speed, and consistency—especially on fine or medium hair—the Dyson is worth the investment.

But if you have thick, coarse, or resistant hair, or you’re willing to invest time in mastering technique, the Shark FlexStyle may actually outperform the Airwrap in curl longevity and styling flexibility. Its wider range of barrel sizes and stronger perceived airflow give it an edge in creating durable, natural-looking waves.

FAQ

Can the Shark FlexStyle replace a traditional curling iron?

For soft waves and natural texture, yes. For tight, bouncy curls that last all night, a ceramic curling iron may still be superior. The FlexStyle reduces heat damage but relies on airflow, which can struggle with very resistant hair types without pre-styling products.

Does the Dyson Airwrap work on short hair?

Yes, especially with the 1.2” barrel. Many users with bobs or lobs report excellent results. The Shark FlexStyle also works on short hair, though the smallest barrel (0.75”) is better suited for tight bends near the crown.

Which tool causes less frizz?

In high-humidity environments, the Shark FlexStyle often wins due to its ability to maintain tension longer and its cooler barrel surfaces. However, on fine hair, Dyson’s gentler heat control minimizes puffiness and flyaways better.

Final Verdict: Comparable, But Not Equal

The Shark FlexStyle and Dyson Airwrap are both exceptional tools, but they serve slightly different audiences. The Dyson delivers a polished, effortless experience with reliable curl hold on average hair types. The Shark offers remarkable value, surprising performance on thicker textures, and greater customization—all at a fraction of the cost.

So, is the curl hold actually comparable? On paper, almost. In practice, it depends. With proper technique, the FlexStyle can produce curls that last just as long—sometimes longer—than those from the Airwrap, particularly in challenging conditions. But it demands more skill, patience, and attention to detail.

If you're looking for a \"set it and forget it\" luxury tool, Dyson remains the leader. But if you want high performance without the premium price—and don’t mind refining your routine—the Shark FlexStyle proves you don’t need to pay top dollar for lasting style.
