Shark FlexStyle Review
It is not trying to be a cheaper Airwrap. It is trying to be a dryer and a styler in one body, which is a different and arguably more useful idea.

Picks are chosen from published specifications, not from hands-on testing; the method is written down so you can check it.
The FlexStyle is almost always written about as a Dyson alternative, and that framing undersells the thing it does that the Dyson does not: the same barrel that dries your hair rotates and becomes a styling tool. One body, two modes, one twist between them.
Whether that matters depends entirely on whether you were going to buy a dryer anyway. If you were, this is one purchase instead of two.

#1 · One tool that dries and styles, on curly or coily hair
Shark FlexStyle Air Styling & Drying System (HD435)
The one multi-styler whose published temperature ceiling is low enough to justify the price on hair that is already fragile, and it converts to a straight dryer in a twist.
| Power | 1,300Wsource |
|---|---|
| Settings | 4 heat and 3 airflow settings, plus a cool shotsource |
| Heat regulation | Measures and regulates temperature 1,000 times per secondsource |
| Weight | Just over 1.5 lbsource |
| In the box (HD435) | Curl-defining diffuser, oval brush, Coanda curlers, styling concentratorsource |
What those numbers mean
One thousand temperature readings per second is not marketing garnish. A dryer that samples that often can hold a target instead of overshooting it, which is the difference between a stated setting and an actual one.
The convertible design is the practical argument. The same barrel that dries your hair rotates to become a styler, so a single purchase covers the drying step and the shaping step rather than two tools that both need storage.
1,300W is below the 1,875W most American dryers advertise. On thick hair that means a longer dry; on curly or coily hair it means the airflow is not shaking the pattern apart while it works.
What it does well
- Published heat regulation at 1,000 readings per second, the tightest figure any brand publishes at this price
- Converts between dryer and styler without swapping tools
- Diffuser and curl attachments come in the box on the HD435 rather than as extras
- Light enough at just over 1.5 lb to hold through a full blowout
What it does not
- 1,300W is genuinely less power than an 1,875W AC dryer, and thick hair will feel it
- The attachment set is bulky to store
- Costs several times what a competent 1,875W dryer costs
Skip this one if: Skip it if what you actually need is a fast dryer for thick hair and nothing else. A 1,875W AC dryer will dry the same head sooner and cost a fraction as much; the FlexStyle price buys styling versatility, not drying speed.

#2 · Curling with air instead of a hot barrel
Dyson Airwrap i.d. Multi-Styler and Dryer
It wraps hair around the barrel with airflow rather than heat, and it holds below 302F while doing it. That is a genuinely different mechanism, not a better version of a curling iron.
| Motor | 13-blade impeller spinning at up to 110,000 rpm, generating 3.2 kPasource |
|---|---|
| Heat control | Intelligent Heat Control keeps the temperature below 302Fsource |
| Heat settings | Three precise heat settingssource |
| Ions | Ionizer adds negatively charged particles to the airflow to reduce staticsource |
| Connectivity | Bluetooth to the MyDyson app for a personalized curling sequencesource |
What those numbers mean
The Coanda effect is the actual product. Fast-moving air over a curved surface pulls nearby air, and hair, along with it — so the barrel wraps the section for you and sets it with airflow rather than by pressing hot metal onto it.
A published ceiling below 302F is the number that justifies the price to anyone with fragile hair. Compare it to a 455F curling iron doing the same job.
It works on damp hair by design, which collapses the dry-then-style sequence into one step. That is where the time saving comes from, not from being faster per section.
What it does well
- Sets curls below 302F, far under any conventional iron
- Dries and styles in one pass from damp
- Three published heat settings and a stated ceiling
- No hot metal in contact with the hair
What it does not
- The most expensive tool in this registry by a wide margin
- Curls set with air drop out faster than curls set with a hot barrel
- A large attachment set to store
Skip this one if: Skip it if you need curls that survive a humid day at work. Air-set curls are gentler and looser, and on hair that resists holding a curl they will fall out well before an iron-set curl would.
Every published specification
| Specification | Published figure |
|---|---|
| Power | 1,300W |
| Settings | 4 heat and 3 airflow settings, plus a cool shot |
| Heat regulation | Measures and regulates temperature 1,000 times per second |
| Weight | Just over 1.5 lb |
| In the box (HD435) | Curl-defining diffuser, oval brush, Coanda curlers, styling concentrator |
One thousand temperature readings per second is the headline figure and it is a genuine engineering claim rather than a coating one — a control loop sampling that often can hold a target instead of overshooting it. What Shark does not publish, and Dyson does, is an absolute ceiling. A regulation rate tells you how tightly it holds a number; it does not tell you what the number is.
The convertible design, assessed
In dryer mode it is a 1,300W dryer. That is real but modest — the thick hair page is full of 1,875W and 2,000W tools, and on dense hair you will feel the difference.
In styler mode it uses Coanda curlers, the same principle as the Airwrap, plus the oval brush for smoothing. The HD435 configuration adds a curl-defining diffuser, which is what makes it the pick on several of our curly and coily pages.
The attachment set matters more than the model number
FlexStyle configurations differ meaningfully. The HD435 reviewed here ships the curl-defining diffuser and Coanda curlers; other configurations swap attachments around. Since the diffuser is the single most important attachment for anyone with a curl pattern, check the specific bundle rather than the product family.
What the specs do not tell you
- The actual temperature. Shark publishes a regulation rate for the FlexStyle, not a ceiling. The SpeedStyle in the same family publishes 230F, which suggests the engineering is there — but a figure for one model is not a figure for another.
- How long the conversion mechanism lasts. A moving joint is a wear point. No manufacturer publishes a cycle count.
- Curl longevity. Air-set curls drop faster than iron-set curls; nobody quantifies by how much.
Who should skip it
Skip it if you already own a dryer you like. Half of what you are paying for is a dryer. If that half is redundant, a dedicated styler or a curling iron is better value.
Skip it if your hair is very thick and drying speed is the problem. 1,300W will not fix that, and no attachment changes it.
Skip it if you need a published heat ceiling. If a stated maximum is why you are shopping, the SpeedStyle publishes 230F and the Airwrap publishes below 302F. The FlexStyle publishes neither.
The verdict
For someone buying one tool to both dry and style, this is the most complete option in the category and the attachment set on the HD435 makes it particularly strong for curly and coily hair. For someone who already has a dryer, it is half a purchase they do not need. The head-to-head against the Airwrap covers the other branch of that decision.
Questions people actually ask
Is the Shark FlexStyle worth buying?
If you need both a dryer and a styler, yes — it is one purchase instead of two, publishes 1,300W and a full settings grid, and the HD435 includes a curl-defining diffuser. If you already own a dryer you like, half of what you are paying for is redundant and a dedicated styling tool is better value.
How hot does the Shark FlexStyle get?
Shark publishes that it measures and regulates temperature 1,000 times per second but does not state an absolute ceiling for the FlexStyle. The SpeedStyle in the same family does publish one — never exceeding 230F — which suggests the same engineering, but a figure for one model is not a figure for another and we will not transfer it.
Is the Shark FlexStyle good for curly hair?
The HD435 configuration is among the best options on this site for curls, mainly because it ships a curl-defining diffuser in the box alongside the oval brush and Coanda curlers. That covers both the diffusing day and the smoothing day with one purchase. Check the configuration — not every FlexStyle bundle includes the diffuser.
Can the Shark FlexStyle dry thick hair?
It can, but not quickly. At a published 1,300W it sits well below the 1,875W and 2,000W dryers we recommend for dense hair, and no attachment changes the airflow the motor produces. If drying speed on thick hair is the problem you are solving, this is not the tool that solves it.
