ghd Helios vs Shark SpeedStyle Pro

Side by side, published only

Eleven of thirteen rows filled on one side, six on the other. The cheaper tool is the one that tells you more, and on this site that is the finding, not an aside: the whole method here is that a figure you can check beats a claim you cannot.

The 230 degree ceiling is the real headline

Shark states that the SpeedStyle regulates its own air temperature a thousand times a second and does not exceed 230°F. We read it from SharkNinja’s HD731 page on 2026-10-17.

Put that next to the rest of this registry and it is remarkable. Almost nothing in this category publishes a temperature: Dyson, T3 and Revlon publish settings counts, and ghd publishes the word “variable.” The exceptions are the L’ange Axia at 140–230°F, the L’ange Le Volume’s three stated settings, the ghd flight+ at a stated 149°F — and this.

And 230°F is low. Every flat iron in this registry sits at 365°F or above. A dryer that caps itself more than 135 degrees below that is making the heat decision for you in the safe direction, which matters because heat is cumulative and the fiber does not recover: repeated thermal cycling measurably degrades hair’s mechanical properties Evans and Park, Journal of Cosmetic Science, and hair that has been bleached or chemically processed starts with measurably less margin to spend Dyer et al., International Journal of Cosmetic Science. Guidance by hair type is at what temperature is actually safe.

One honest caveat, the same one we give everywhere: a published regulation ceiling is not the temperature at your hair, which depends on distance, dwell time and airflow. Neither maker publishes a figure for that, and nor does anyone else.

125 watts, and what it is worth

1,875 W against 1,750 W is a gap of about 7 percent, and it is the single row ghd wins outright.

It is worth less than it looks. Wattage is the draw of the heating element: it bounds how much heat a dryer can produce and says nothing about how much air moves or how evenly. The proof is already on this site — the ghd Helios publishes exactly the same 1,875 W as the Revlon SmoothStay, the cheapest dryer in this registry, and the Hot Tools Pro Artist publishes it too. ghd Helios vs Revlon SmoothStay is that tie read against the price tag, and wattage explained is the general argument.

Running cost, assumptions stated: at 65 hours a year and the U.S. average residential rate of 18.34 cents per kilowatt-hour, 1,875 W is about $22.35 a year and 1,750 W about $20.86. A dollar and a half should not decide anything — running costs has the formula — but it is arithmetic you can only do because both makers publish the input, which is more than most of this category manages.

The row ghd leaves blank is the one you feel

Shark publishes 1.65 lb. ghd publishes no weight for the Helios at all.

On a dryer that is the specification you notice most, because you hold it above your head with your arm bent for the length of a blow-dry. Shark’s 1.65 lb sits below the Dyson Supersonic’s published 1.8 lb and well above the L’ange Axia’s 0.7 lb, so it is mid-pack and knowable. The Helios is unknowable, and “probably similar” is not something we will publish.

It matters most where sessions run long. On long or dense hair the weight row is the one that decides whether you finish the job properly — dryers for long, thick hair ranks on exactly that, and dryers for long hair is the length-only version.

What arrives in the box, and the change we found

ghd publishes no attachment list for the Helios. Shark does, and what it publishes has changed since we first recorded it.

On the HD731 page as read on 2026-10-17, Shark lists four things in the box: the dryer, a FrizzFighter finishing tool, a QuickSmooth brush and a Turbo concentrator. Three further items — the DefrizzFast diffuser, the lift-and-stretch wide-tooth comb and the express touch-up brush — are now listed as sold separately, alongside a storage bag. Our earlier reading of this product named all of those as attachments without that split.

The practical consequence is one you should act on rather than trust us for: Shark sells this dryer in configurations, so check the in-the-box list on the exact listing you are buying, especially if the diffuser is the reason you are buying it. If your hair is curly or coily, the diffuser is not an accessory — diffuser vs concentrator and which dryers publish a diffuser both turn on that row. The Hot Tools Pro Artist on the buy list above publishes both a diffuser and a concentrator in the box and does not configure.

Neither travels, and ghd says so plainly

Shark publishes 120 V. ghd states outright that the Helios is not universal voltage, which is a more useful blank than a blank — it is a maker telling you not to pack it.

Both therefore need a converter rather than an adapter on a 230 V supply, and those are different objects that look alike: adapter vs converter. The only dual-voltage dryer in this registry is the ghd flight+, from the same brand — travel dryers and the full dual-voltage list.

The honest case for the Helios

Three real things. It publishes the higher wattage and the longer cord — 9 ft against 8 ft, and a foot of cord is a genuine difference in a bathroom with one socket. It publishes a cool shot as part of its variable temperature control, which Shark does not publish at all, and cooling is when hair takes its shape. And ghd states a brushless motor for longer life, which is a durability claim rather than a performance one.

There is also the professional argument. ghd publishes a two-year consumer warranty and a one-year professional warranty, which is an unusually honest piece of disclosure: it tells you the company expects salon duty to use the tool up faster. Nobody else in this registry publishes a duty-cycle distinction at all — what a professional dryer actually is and are professional hair tools actually different both go through it. The single sheet is at the ghd Helios review.

Which one to buy

• Buy the Shark if you want figures you can check. Weight, cord, amperage, dimensions and a temperature ceiling, against six filled rows out of thirteen.
• Buy the Shark if your hair is fine, colored or bleached. A published 230°F ceiling is the strongest heat-discipline row available in this category — dryers for color-treated hair.
• Buy the Shark on price. It is the cheaper tool and the better-documented one, which is the dupe argument working exactly as advertised — Shark vs Dyson.
• Buy the Helios for cord reach and a cool shot. 9 ft against 8 ft, and the only published cool setting of the two.
• Buy the Helios if you style other people. The published professional-versus-consumer warranty split is the only duty-cycle disclosure in this registry.
• Neither, if you travel. 120 V and explicitly-not-universal, respectively. The ghd flight+ is the only dryer here that publishes dual voltage.
• Neither, if you need a diffuser guaranteed in the box. ghd publishes no list; Shark’s depends on the configuration. The Hot Tools Pro Artist publishes both attachments and is the cheapest tool of the three.
• Neither, if weight is your deciding row and you want it light. 1.65 lb is mid-pack and the Helios does not publish one at all. The L’ange Axia publishes 0.7 lb.

What we could not compare

Noise, on both, and on every tool in this registry — no maker publishes a decibel figure, which is why dryer noise explains the absence rather than ranking it. Weight on the Helios. The attachment list on the Helios. Any temperature figure on the Helios. Heat and speed setting counts on the Shark, which is an odd blank on a tool that publishes its own ceiling. Airflow volume on both: Shark’s 0–100 mph is a claim about speed, not volume, and ghd publishes nothing. And drying time on both, because no maker publishes one and there is no standard test.
