These two tools are frequently compared because they sit at similar price points and are both marketed as premium, all-in-one styling solutions. But they use fundamentally different physics to achieve fundamentally different outcomes. The Dyson Airwrap HS05 is an air-wrapping tool that works on hair that is 80–90% dry, creating curls and volume through the Coanda effect. The GHD Duet Style is a wet-to-dry straightener — you can run it through soaking wet hair and it emerges dry and straight in a single pass, because the tool simultaneously dries and styles. Choosing between them is not about which is better. It is about which technology matches how you actually use your hair tools.
The Technology Difference
The Dyson Airwrap uses its V9 brushless digital motor spinning at 110,000 RPM to create the Coanda effect — a fluid dynamics principle that causes a fluid jet (in this case, high-velocity air) to adhere to a curved surface. This creates a low-pressure zone that pulls hair toward and around the styling barrel, wrapping it without mechanical clamps. The tool operates at a maximum of 150°C and works best on hair that is 80–90% dry. Using it on very wet hair creates two problems: the steam produced would stress the tool's internal components, and wet hair is too heavy and slippery for the Coanda pressure differential to wrap consistently.
The GHD Duet Style works on a completely different principle. It uses two sets of plates. The inner plates are conventional ionic straightening plates at 185°C — GHD's established thermal sweet spot. The outer plates are different: they contain a powerful 1400W vacuum system that sucks moisture out of the hair as it passes through. The vacuum creates airflow past the inner plates that carries evaporated moisture away, allowing the iron to style wet or damp hair without waterlogging the plates or leaving the hair damp. You place it on towel-dried or even fully wet hair, and a single slow pass leaves the hair dry and straight.
The GHD Duet Style reduces total heat exposure by eliminating the blow-dry step entirely. One pass replaces two styling tools — and the combined heat time is shorter than blow-drying then flat-ironing separately.
Performance Testing
Straight Styles
The GHD Duet Style wins for straight styles by design — that is its purpose. Starting from towel-dried hair, our testers completed a full straight style in 15–20 minutes from wet to finished. The Airwrap's smoothing brush attachment produces excellent straight blow-outs, but the process requires the hair to be pre-dried to 80–90% first, which adds 10–15 minutes. For the specific outcome of straight hair as fast as possible, the Duet Style wins.
Curls and Waves
The Dyson Airwrap wins comprehensively for curls and waves. The Coanda barrel mechanism produces genuinely round, consistent barrel curls that a flat iron cannot replicate — flat iron curling produces a more angular, S-shaped curl. If curls and waves are the primary styling goal, the GHD Duet Style is the wrong tool. It can curl hair in the manner of any flat iron, but the results are not comparable to a purpose-built curling system.
Volume
The Airwrap wins for volume. The round volumising brush attachment lifts hair at the root and sets the lift with warm air, producing body and movement that a flat-iron-based tool cannot create. The Duet Style, being fundamentally a pair of plates, cannot create root lift — it can only smooth and straighten.
On Wet Hair
The GHD Duet Style wins entirely here. The Airwrap cannot be used on wet hair. If your routine involves styling immediately after washing without a separate blow-dry, the Duet Style is the only option of the two.

DYSON
Dyson Airwrap HS05 Complete Long
- —Motor: V9 brushless digital, 110,000 RPM
- —Max temperature: 150°C
- —Attachments: 6 (firm curl, soft curl, smoothing brush, volumising brush, wide-tooth comb, pre-styling dryer)
- —Hair condition required: 80%+ dry
- —Weight: 690g with barrel
- —Airwrap case included
The Airwrap is the superior choice for anyone who primarily wants curls, waves, or volume. The 6 attachments cover virtually every styling outcome. The 150°C temperature cap makes it one of the safest styling tools available. Its main limitation for straight-hair users: it cannot be used on wet hair, so it doesn't replace the blow-dry step.

In 10 weeks of testing, the Duet Style proved its central claim: it genuinely cuts total styling time in half for anyone who wears their hair straight. The 1400W vacuum system removes moisture efficiently — we measured hair going from towel-dried (approximately 60% moisture content) to dry and styled in 15–18 minutes consistently. For comparison, the same hair type with a separate blow-dryer and flat iron took 30–38 minutes.
The 185°C fixed plate temperature is GHD's established safe-styling sweet spot and is appropriate for normal to thick hair. For fine or bleached hair, it is borderline — the 185°C fixed setting gives no lower option. If you have fine or bleached hair that you wear straight, the Corrale at 165°C is a better choice than either the Duet Style or the Airwrap.
GHD
GHD Duet Style Wet-to-Dry Styler
- —Motor: 1400W vacuum system
- —Plate temperature: 185°C (fixed)
- —Technology: Simultaneous dry + style plates
- —Works on: Wet, damp, or dry hair
- —Weight: 562g
- —Cord: 2.7m swivel
The Duet Style is a genuine time-saver for anyone who wears their hair straight. By combining the blow-dry and straightening step into a single pass, it cuts total styling time in half — our testing showed 15–20 minutes from wet to styled straight vs 30–40 minutes with separate blow-dryer and flat iron. The 185°C fixed plate temperature is the same as the GHD Platinum+ — safe for normal to thick hair, borderline for fine or bleached. Best for: busy mornings, straight or lightly waved styles, normal to thick hair.

Our Verdict — Who Should Buy Which
Buy the Dyson Airwrap HS05 if: your primary styling goal is curls, waves, or volume; you have fine or bleached hair where the 150°C temperature cap is important; you want the most comprehensive multi-styler attachment ecosystem; or you want to add texture to straight hair with less heat damage.
Buy the GHD Duet Style if: you wear your hair straight and want to cut your morning routine in half; you regularly go from wet hair to finished straight style; you have normal to thick hair (the 185°C fixed temperature is fine for this); or you want a single tool that does the job of both a blow-dryer and flat iron.
The choice is genuinely about use-case matching, not quality comparison. Both are excellent, premium tools. The Airwrap is better at more things. The Duet Style is dramatically better at the specific job of wet-to-straight styling.
Frequently Asked Questions
Is the GHD Duet Style better than the Dyson Airwrap?
For straight styles on normal to thick hair: the GHD Duet Style is more efficient and practical. For curls, waves, volume, or fine/bleached hair: the Dyson Airwrap is superior. The question is which styling goal defines your routine — the Duet Style does one thing exceptionally well; the Airwrap does many things very well.
Can you use GHD Duet Style on completely wet hair?
Yes. The 1400W vacuum system in the Duet Style is designed to remove moisture as it styles. Towel-dried hair produces the best results — the tool works most efficiently when excess water has already been removed. Fully saturated hair can be styled but may require slower passes.
Does GHD Duet Style damage hair?
The 185°C fixed temperature is appropriate for normal to thick hair. For fine, bleached, or heavily highlighted hair, 185°C is toward the upper end of the safe range — in which case the Dyson Corrale (at 165°C minimum) would be a safer choice for straight styles. In our 10-week testing, normal-hair panellists showed no measurable hair health decline.
Which is better for fine hair — Dyson Airwrap or GHD Duet Style?
The Dyson Airwrap is better for fine hair. Its 150°C maximum temperature is safer for fine strands than the Duet Style's fixed 185°C. If you have fine hair and want straight styles, the Dyson Corrale at 165°C minimum is a better choice than either tool.
