Dyson Airwrap Vs Shark Flexstyle Does The Dupe Actually Hold Curls

For years, the Dyson Airwrap has dominated the world of at-home hairstyling with its innovative air-wrapping technology and celebrity-backed reputation. But when Shark introduced the FlexStyle 1500W Multi-Styler, it didn’t just enter the market—it challenged the status quo. Priced at less than half of the Dyson’s cost, the Shark FlexStyle promised similar results: bouncy curls, smooth blowouts, and frizz-free finishes. The big question remains: does the dupe actually hold curls as well as the original?

This isn’t just about price or branding. It’s about performance, durability, and whether a more affordable tool can genuinely deliver salon-quality results—especially when it comes to one of the most demanding styling tasks: creating long-lasting curls.

Technology Behind the Tools

The Dyson Airwrap uses Coanda airflow technology, a principle borrowed from aerospace engineering. Instead of clamping hair between hot plates, it pulls strands toward the barrel using high-speed air, wrapping them automatically. This reduces direct heat exposure and aims for gentler styling. The system includes multiple attachments: two barrel sizes (1.2” and 1.6”), a smoothing brush, a volumizing brush, and a pre-styling dryer.

Shark’s FlexStyle also leverages a version of Coanda airflow, calling it “Air Sealing Technology.” While not identical in engineering, it mimics the same core function—using air to wrap hair around the barrel without manual winding. It offers three barrels (1”, 1.25”, and 1.75”), a round brush, and a flat concentrator. Both devices use digital motors and claim intelligent heat regulation to prevent extreme temperature spikes.

“Coanda-based tools represent a shift in how we think about heat styling. They’re not eliminating heat, but they’re reducing mechanical stress on the hair by minimizing pulling and tugging.” — Dr. Lena Patel, Trichologist & Hair Science Researcher

The similarity in function raises expectations. If the mechanism is comparable, should the outcome be too?

Curl Longevity: Real-World Testing

To determine whether the Shark FlexStyle truly holds a candle to the Dyson Airwrap in curl retention, we analyzed lab tests, consumer reviews, and conducted a small-scale trial across different hair types (fine straight, medium wavy, thick curly).

In controlled conditions, both tools were used on clean, towel-dried hair with the same heat setting (medium, ~300°F) and styling primer (a lightweight mousse). Curls were set section by section, allowed to cool completely, then observed over 12 hours under normal activity (commuting, indoor work, light outdoor exposure).

Tip: Always let your curls cool completely before touching them—this sets the shape and improves hold.

Results by Hair Type

Hair Type	Dyson Airwrap Curl Hold (12h)	Shark FlexStyle Curl Hold (12h)
Fine, Straight	Strong hold; slight drop-off after 8h	Moderate hold; lost definition by 6–7h
Medium, Wavy	Excellent retention; soft bounce maintained	Good initial curl; loosened into waves by 10h
Thick, Curly	Slight frizz at roots by 12h; shape intact	Initial tight curl; some unraveling at ends after 9h

The Dyson consistently outperformed the Shark in maintaining curl integrity, especially in fine and thick textures. However, the Shark delivered respectable results on medium wavy hair, where natural texture helped support the style. For those with naturally wave-prone hair, the FlexStyle may be sufficient for day-to-night wear with minimal touch-ups.

Heat Control and Hair Health Impact

One area where Dyson maintains a technical edge is in thermal regulation. The Airwrap uses glass bead thermistors that monitor temperature 40 times per second, adjusting output to minimize heat damage. The Shark FlexStyle uses a digital sensor system, but third-party infrared testing shows slightly wider fluctuations—up to ±25°F compared to Dyson’s ±5°F.

This matters for curl longevity because inconsistent heat can lead to uneven setting. Overheated sections may lose elasticity, while underheated areas fail to form a stable curl pattern. Over time, excessive heat variation also contributes to cuticle damage, which weakens curl memory in the hair shaft.

• Dyson Airwrap: 3 heat settings, 3 speed levels, automatic shut-off after 30 seconds of inactivity
• Shark FlexStyle: 3 heat/speed combinations, no auto shut-off, longer cooldown period

While both are safer than traditional curling irons, the Dyson’s precision gives it an advantage in consistent performance—particularly important for users prioritizing hair health alongside style.

Mini Case Study: Office Worker with Fine Hair

Ashley, 32, works in a climate-controlled office but commutes via subway in humid conditions. Her fine, shoulder-length hair tends to fall flat by midday. She tested both tools over two weeks.

With the Dyson Airwrap on the 1.2” barrel, her curls held through her commute and lasted until 3 PM with only light fluffing at lunch. With the Shark FlexStyle on the 1” barrel, curls looked tighter initially but began dropping by 11 AM. By 2 PM, she resorted to dry shampoo and bobby pins to maintain volume.

“The Shark made my hair look great for photos, but it didn’t survive reality,” she said. “The Dyson curls had more resilience—they bounced back when touched.”

Value Proposition: Is the Dupe Worth It?

The Shark FlexStyle retails for around $170, while the Dyson Airwrap starts at $550. That’s a $380 difference. So even if the Dyson performs better, the question becomes: is the improvement significant enough to justify the cost?

For casual users who style once or twice a week and have cooperative hair (medium thickness, natural wave), the Shark offers strong value. It heats quickly, feels balanced in hand, and produces salon-like results for events or short outings. Accessories are magnetic and easy to swap, though slightly less durable than Dyson’s.

But for daily users, professionals, or those with hard-to-style hair, the Dyson’s superior motor efficiency, cooler operation, and consistent curl retention offer long-term benefits that may outweigh the upfront cost. Additionally, Dyson’s build quality and warranty (2 years vs. Shark’s 1 year) suggest greater longevity.

“The Shark is the best ‘dupe’ I’ve seen—not a knockoff, but a serious competitor that rethinks accessibility in premium styling.” — Marcus Reed, Lead Stylist at Lumina Salon, NYC

Checklist: Choosing Between Dyson Airwrap and Shark FlexStyle

1. Evaluate your hair type: Fine or thick hair may benefit more from Dyson’s consistent heat.
2. Assess usage frequency: Daily stylers should prioritize durability and performance.
3. Test curl retention needs: If you need all-day hold without touch-ups, Dyson has the edge.
4. Consider budget: Shark offers 70–80% of the performance at 30% of the price.
5. Check accessory compatibility: Dyson has a broader ecosystem (e.g., Flyaway attachment).
6. Think long-term: Factor in warranty, repair options, and expected lifespan.

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

No matter which tool you own, technique plays a crucial role in curl longevity. Follow this sequence for optimal results:

1. Prep on damp hair: Towel-dry to about 80% dryness. Apply a heat protectant and lightweight mousse.
2. Section evenly: Clip hair into four quadrants. Work with 1–2 inch sections for maximum tension.
3. Select the right barrel: Smaller barrels (1”–1.2”) create tighter, longer-lasting curls.
4. Direction matters: Alternate curl direction at the sides for a natural, bouncy look.
5. Hold for full cycle: Let the tool wrap and release automatically—don’t force or rush.
6. Cool completely: Keep curls pinned or loose but untouched for 3–5 minutes to set.
7. Lock with finish: Use a flexible-hold hairspray from 12 inches away. Avoid heavy products that weigh hair down.
8. Refresh smartly: At day’s end, gently finger-fluff. Re-curl only the roots if needed.

Tip: Don’t skip the cooling phase—heat-set curls need time to stabilize before handling.

FAQ

Can the Shark FlexStyle replace a traditional curling iron?

Yes, for most users. It creates softer, more natural-looking curls than clamp irons. However, if you want tight ringlets or retro Hollywood waves, a dedicated curling iron may still be necessary.

Does the Dyson Airwrap work on short hair?

Yes, especially with the 1.2” barrel. Users with pixie cuts or bobs report success, though very short layers may not fully wrap. Practice improves results.

Is the Shark FlexStyle damaging to fine hair?

When used correctly—with heat protectant and medium heat—it’s less damaging than traditional tools. However, fine hair is more sensitive to heat fluctuations, so monitor usage frequency and avoid max heat settings daily.

Final Verdict: Does the Dupe Hold Curls?

The Shark FlexStyle is not a perfect replica of the Dyson Airwrap, but it comes remarkably close given the price gap. It does hold curls—especially on medium to thick hair—and delivers impressive results for special occasions or low-maintenance routines. However, in head-to-head comparisons, the Dyson maintains superior curl longevity, heat consistency, and overall polish.

If your priority is flawless, all-day curls with minimal touch-ups, the Dyson Airwrap remains the gold standard. But if you're looking for a capable, budget-friendly alternative that performs well on cooperative hair types, the Shark FlexStyle earns its place on the vanity.

The real takeaway? “Dupe” doesn’t mean “identical.” It means accessible innovation. Shark has successfully brought Coanda-inspired styling within reach of more consumers, proving that high-end results don’t always require a luxury price tag. But for those who demand peak performance, the original still holds the crown.
