The short answer

Shark FlexStyle HD440 comes out ahead by a clear margin (3.6 vs 4.5). The gap is mostly about Shoppers who want one tool that both dries fast and styles, especially anyone eyeing a Dyson Airwrap but unwilling to pay Airwrap money. — read the strengths below before deciding.

Ranked #5 in Best Fast-Drying Hair Dryers
Conair InfinitiPro 1875W
3 sources2 derived$35.66as of Aug 1

The Conair InfinitiPro 1875W is the budget pick and proof you do not need to spend hundreds to dry hair fast. Its pro AC motor dries up to 50% faster than Conair's DC dryers, and TechGearLab found it dried with 'above-average expedience' even as its overall 57/100 score reflects the basic build. It is loud, simple, and short-corded. For around $40 with a diffuser and concentrator in the box, the value is excellent.

Strengths
  • A genuine budget fast-dryer: the pro AC motor dries up to 50% faster than Conair's DC-motor models and lasts up to 3x longer
  • Costs a tiny fraction of premium rivals while still drying with 'above-average expedience' in TechGearLab testing
  • Includes both a concentrator and a diffuser, covering straight and curly routines
Watch-outs
  • Lowest-scoring dryer here at 57/100 in TechGearLab testing; very basic versus premium tools
  • Runs loud, a near-universal complaint among owners
  • Cord is shorter than average (under 6 ft), which can be restrictive

2 sourcesall derived$369.99as of Aug 1

The Shark FlexStyle HD440 does double duty: a genuinely fast dryer that also converts into a full multi-styler with auto-wrap curlers, widely regarded as the affordable Dyson Airwrap alternative. It carries a 4.4 out of 5 average on Shark's listing along with strong editorial reviews from TechRadar and others. As a pure dryer it trails the HyperAIR. No other tool here covers as much drying-plus-styling ground for the money.

Strengths
  • Doubles as a fast, high-airflow dryer and a full multi-styler with auto-wrap curlers, an Airwrap-style trick at a fraction of the price
  • Holds a 4.4 out of 5 average on Shark's own listing across its large review base
  • Heat-controlled ceramic regulates temperature 1,000 times per second to limit heat damage
Watch-outs
  • As a pure dryer it is less powerful than the dedicated HyperAIR, and TechRadar notes you dry to about 80% before styling
  • Fine or very straight hair may see auto-wrap curls fall to soft waves within hours
  • Heavier and bulkier in the hand than a simple dryer, and the diffuser is noticeably large

How they stack up

Conair InfinitiPro 1875W

The cheapest and most basic dryer here. It does not match the airflow control of the Dyson Supersonic, the raw speed of the Shark HyperAIR HD120, the styling range of the Shark FlexStyle HD440, or the blowout finish of the Drybar Buttercup, but its AC motor dries far faster than its price suggests.

Shark FlexStyle HD440

Unlike the Dyson Supersonic and Shark HyperAIR HD120, which are pure dryers, the FlexStyle HD440 converts into a multi-styler with auto-wrap curlers. It dries a touch slower than the HyperAIR HD120 but offers styling those dryers cannot, and it undercuts the Dyson on price while adding curling.
