Shark Flex Fusion vs Dyson Airwrap + Airstrait: One Tool Replaces Two ($700+ Savings)

Quick version: The Shark Flex Fusion is the only hair tool that does BOTH jobs: the multi-styling that the Dyson Airwrap is famous for (curls, waves, blowouts), AND the wet-to-dry straightening that you would otherwise need a Dyson Airstrait to do. One Shark Flex Fusion at around $330 replaces $1,098+ in Dyson tools. I own all four: the Shark FlexStyle, the Shark Flex Fusion, the Dyson Airwrap, AND the Dyson Airstrait. I have used them all in my own bathroom, side by side, over the past few years.

This is for all my beauty tool-loving friends who have been asking me which one to buy! I get the Shark versus Dyson question MANY times a week, and now that I have actually used all four tools, I have a real answer. The Airwrap and the Airstrait are both really nice products. I still like them. I am not knocking Dyson. But once you have used the Flex Fusion side by side with both of them, the math is hard to ignore. Shark released the Flex Fusion this year as the bigger sister to the FlexStyle I have raved about forever. It keeps everything the FlexStyle does (auto-wrap curls, blowout brush, concentrator) AND adds the one thing the FlexStyle did not do well: wet-to-dry straightening, the exact job the Dyson Airstrait was built for.

So now the real comparison is not Shark vs Dyson. It is ONE Shark Flex Fusion vs the combo of TWO Dyson products. And the price gap is wild.

Two things I want to call out specifically as someone who owns all four: the steel on the Flex Fusion is insane. I would not have expected it from a tool at this price, but the build feels solid in a way that genuinely surprised me. And the Flex Fusion has less of a learning curve. I think it is easier to learn to use than the Airwrap, especially if you are new to multi-styler tools. The Dyson has that signature Coanda technique that takes practice, and the Flex Fusion gets you to the result faster.

The price math: $330 vs $1,098

Let's lay out the actual numbers (current retail prices, before any Prime Day discount):

• Shark Flex Fusion: around $330 retail (currently on Prime Day discount)
• Dyson Airwrap: around $599
• Dyson Airstrait: around $499
• Dyson combo total to match Flex Fusion: about $1,098
• Savings by going with the Shark Flex Fusion: about $768+

That is not a small difference. That is more than $700 you keep in your account by choosing one Shark instead of two Dysons that, together, do the same set of styling jobs.

What the Shark Flex Fusion does (and why it bridges two Dyson tools)

Per the Shark listing, the FlexFusion uses Style-Safe Technology that combines powerful air with heat-controlled ceramic for “no heat damage styling with hot-tool results.” The 5-in-1 system includes:

• Wet-or-dry fusion straightener: a ceramic iron designed to deliver smooth straight styles in just a few passes, with the brand noting significantly less risk of heat damage. This is the attachment that does the Airstrait's job.
• Wet-or-dry fusion brush: a round brush with a mix of boar and nylon bristles for blowouts and volume.
• Auto-wrap curlers: Shark's version of the Dyson Coanda barrels. They wrap, curl, and set hair automatically.
• Concentrator: for traditional blow drying.
• FrizzFighter Finishing Tool: a smaller attachment for flyaways and high-gloss finish.

The Scalp Shield feature was dermatologist-developed and can be activated to instantly adjust temperatures and protect the scalp from extreme heat. The whole tool weighs about 1.74 pounds.

Why this matters for the Dyson comparison: the FlexStyle (the previous Shark model I own) was a great Airwrap alternative, but it could not really straighten wet hair the way you would want for a sleek look. The FlexFusion solves that. Now ONE Shark tool covers both the curling/styling category AND the wet-to-dry straightening category. CNN Underscored called it “the only hair tool that can tame my unruly hair” in their review.

What the Dyson Airwrap does (and what it does NOT do)

The Dyson Airwrap is the original air styler. It uses Coanda effect technology so the air pulls hair around the barrel automatically, and it has been the gold standard for curls, waves, and salon-quality blowouts for years.

What the Airwrap does well, per the Dyson listing and from my own experience:

• Bouncy, salon-style blowouts
• Defined curls and waves with the auto-wrap barrels
• Smoothing dry hair without flatness
• Premium feel and balance in the hand

What the Airwrap does NOT do well:

• Wet-to-dry straightening. The Airwrap can dry hair and smooth it, but if you want a sleek, stretched straight look from soaking-wet hair, this is not the tool. That is exactly why Dyson made the Airstrait as a separate product.
• Save you money. Retail is around $599, and the price almost never drops significantly.

What the Dyson Airstrait does (and what it does NOT do)

The Dyson Airstrait is a different tool with one job: straightening hair while drying it. It uses downward airflow between two arms to dry and straighten in one pass.

What the Airstrait does well, based on my own use and side-by-side testing:

• Sleek wet-to-dry straightening in one tool
• Lighter and more ergonomic than the Flex Fusion straightener attachment, per a Woman & Home side-by-side review
• Can dry a larger section of hair more quickly with a smoother finish than the Shark straightener attachment
• Best-in-class if a stretched blowout or pin-straight finish is your ONLY goal

What the Airstrait does NOT do:

• Curls. At all. The Airstrait is a one-look tool. If you ever want a wave, a curl, or a bouncy blowout, you need a second tool.
• Save you money. Retail is around $499.

This is the key point: the only reason most people would buy the Airstrait is BECAUSE the Airwrap does not straighten wet hair well. So if you go the Dyson route, you almost have to buy both tools. That is how you end up at $1,098.

Shark Flex Fusion vs Dyson Airwrap vs Dyson Airstrait: side-by-side

Here is the comparison broken down by feature:

• Wet-to-dry straightening: Flex Fusion ✓ | Airwrap ✗ | Airstrait ✓
• Auto-wrap curls: Flex Fusion ✓ | Airwrap ✓ | Airstrait ✗
• Blowout brush attachment: Flex Fusion ✓ | Airwrap ✓ | Airstrait ✗
• Concentrator: Flex Fusion ✓ | Airwrap ✓ | Airstrait ✗
• Smoothing finisher attachment: Flex Fusion ✓ (FrizzFighter) | Airwrap ✗ | Airstrait ✗
• No-heat-damage messaging: Flex Fusion ✓ (Scalp Shield) | Airwrap ✓ | Airstrait ✓
• Approximate retail price: Flex Fusion $330 | Airwrap $599 | Airstrait $499
• Tools needed to do everything: Flex Fusion = 1 tool | Dyson = 2 tools ($1,098)

Reviewer note from Woman & Home's side-by-side comparison: the Airstrait does have a smoother, sleeker finish than the Flex Fusion's straightener attachment when comparing pure straightening, and the Airstrait is lighter and more ergonomic. The trade-off is that the Airstrait does only one thing.

Reviewer note from a tested comparison: the Shark “feels more plastic-heavy” but delivers “90% of the performance for 60% of the price.”

Who should buy the Shark Flex Fusion vs the Dyson Airwrap or Airstrait

Get the Shark Flex Fusion if:

• You want versatility (curls, blowouts, AND wet-to-dry straightening) in ONE tool
• You do not want to spend more than $400 on hair tools
• You like the idea of one cord, one charger, one storage spot
• You appreciate “no heat damage” messaging backed by ceramic plates + scalp protection
• You are upgrading from a basic dryer or flat iron and want a real glow-up without going premium

Get the Dyson Airwrap if:

• Curls and bouncy blowouts are your priority and you are not concerned with straightening wet hair
• Budget is not a major factor and you want the premium build, balance, and feel
• You want the original Coanda technology that the entire category is built around

Get the Dyson Airstrait if:

• A stretched, sleek straight look is the only style you want, and you have separate tools for everything else
• You prioritize the best straightening performance and finish, full stop
• Lighter weight and ergonomics matter more than versatility for you

Get BOTH Dyson tools (Airwrap + Airstrait) if:

• You want premium across the board and the $1,098 price tag is fine with you
• You believe the build, longevity, and finish quality differences justify the gap
• You wanted to read this comparison anyway, but you already knew you would buy Dyson

Shark Flex Fusion vs Dyson FAQ

Is the Shark Flex Fusion as good as the Dyson Airwrap?

For the curling, waving, and blowout jobs, the Flex Fusion's auto-wrap curlers and brush attachments deliver similar results to the Dyson Airwrap at a fraction of the cost. The Dyson generally has a more premium build and balance, but reviewers consistently note that the Shark delivers about 90% of the performance for around 60% of the price. The Shark also does wet-to-dry straightening, which the Airwrap does not.

Is the Shark Flex Fusion as good as the Dyson Airstrait?

For wet-to-dry straightening alone, side-by-side reviews (including Woman & Home) found that the Airstrait is lighter, more ergonomic, and produces a smoother, sleeker straight finish than the Flex Fusion's straightener attachment. That said, the Airstrait is a one-look tool that costs around $499 and only straightens. The Flex Fusion straightens wet hair AND does curls, waves, blowouts, and finishing for under $400 total.

How much do you save buying the Shark Flex Fusion instead of both Dyson tools?

The Shark Flex Fusion retails around $330. The Dyson Airwrap retails around $599. The Dyson Airstrait retails around $499. If you would otherwise buy both Dyson tools to get full styling versatility, the Flex Fusion saves you about $768 (and even more during Prime Day sales).

Does the Shark Flex Fusion replace both the Dyson Airwrap and the Dyson Airstrait?

Yes, in terms of FUNCTION. The Flex Fusion combines the wet-to-dry straightening that the Airstrait is built for with the auto-wrap curls, blowout brush, and concentrator that the Airwrap is built for. The difference is in finish quality and build feel, where the Dyson tools each have a slight edge in their narrow specialty, but the Flex Fusion bridges both jobs in one tool.

Is the Shark Flex Fusion the same as the Shark FlexStyle?

No. The FlexStyle was Shark's first multi-styler (the direct Dyson Airwrap competitor). The FlexFusion is the newer, bigger-sister model that adds the wet-or-dry fusion straightener attachment, so it can do everything the FlexStyle does PLUS wet-to-dry straightening. If you already own the FlexStyle and love it, the Flex Fusion is the upgrade if you also want the Airstrait-style straightening.

Is the Shark Flex Fusion worth it for fine or damaged hair?

The brand's Style-Safe Technology and dermatologist-developed Scalp Shield are designed to deliver hot-tool results without extreme heat. Many reviewers with fine or color-treated hair specifically mention reduced heat damage compared to traditional flat irons and curling wands. Your stylist is the best person to ask for a personal recommendation based on your hair type.

Bottom line

If you have been going back and forth on whether to get the Dyson Airwrap, the Dyson Airstrait, or both, and your styling goals include curls AND straightening, the Shark Flex Fusion gives you one tool that covers both jobs for about a third of the price. It is the easiest “yes” in the category right now, especially during Prime Day.
