When it comes to the curling attachments, both tools use the Coanda effect (yes, I Googled that too). The Dyson still creates slightly more polished, longer-lasting curls—especially on fine hair. But honestly? The Shark’s curls were almost identical after I figured out how to use the barrels properly. (Tip: Hold the curl for longer and set with cool air.)

Ease of Use

There’s a learning curve with both devices, but the Shark wins for simplicity. The controls are straightforward, and switching attachments is quick and intuitive. I also appreciated that the Shark isn’t overly reliant on gimmicky features—it just works. The Dyson sometimes feels like it’s trying to impress you with its IQ instead of focusing on ease.

One small downside with the Shark: it’s loud. Not lawnmower-level loud, but definitely louder than the Dyson. Not a dealbreaker, just something to note if you style your hair early in the morning or while your partner’s still sleeping.

Price Point: The Deciding Factor

This is where Shark really shines. The full FlexStyle kit comes in at almost half the price of the Dyson—and sometimes even less if there’s a sale. For most people, that difference is hard to ignore, especially when the results are 85–90% identical.

Unless you’re a hair tool collector or die-hard Dyson loyalist, the Shark offers more than enough performance for the average user. It’s a steal in comparison.

Final Thoughts: Is It a True Dupe?

If by “dupe” you mean “gets the job done for less money while looking somewhat similar,” then yes—the Shark FlexStyle is absolutely a Dyson dupe. But if you expect every curl to last 24 hours and the finish to be identical, know that there’s a slight trade-off in refinement and polish.

Verdict:

  • Dyson is best for: heat-sensitive hair, ultra-polished finishes, and those who love tech-y beauty tools

  • Shark is best for: budget-conscious stylers, everyday use, and people who want serious results without the bells and whistles

Bottom line: The Shark FlexStyle might not have the luxury feel of the Dyson, but it more than delivers where it matters most—your hair.
