Ranked #5 in Best Fast-Drying Hair Dryers

Conair InfinitiPro 1875W

4.2

$46.99as of Jun 7

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 its basic build. It is loud, simple, and has a short cord, but 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

Higher ratedRanked #1 in Best Fast-Drying Hair Dryers

Dyson Supersonic

4.7

$355.69as of Jun 7

The Dyson Supersonic is the benchmark fast-drying dryer and the dryer most others are measured against. TechGearLab scored it 86 out of 100, the top mark in their test group, praising its powerful, well-controlled airflow and handle-mounted motor. It is not always the single fastest in raw minutes, but its combination of speed, low heat damage, balance, and quiet operation is unmatched. The price is the only real barrier.

Strengths

— Highest-ranked dryer in TechGearLab's lab testing (86/100), with airflow that cut drying time roughly in half versus a standard dryer
— Digital V9 motor sits in the handle, so the tool is exceptionally well-balanced and light on the wrist during long blowouts
— Intelligent heat control measures air temperature many times a second to keep the dryer from scorching hair

Watch-outs

— Among the most expensive consumer hair dryers on the market at around $430
— In one head-to-head test it took 30 minutes to fully dry thick hair versus 20 for the Shark HyperAIR, so it is not always the literal fastest
— Replacement and accessory costs are high, and the proprietary attachments do not fit other brands

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.

Dyson Supersonic

Faster and quieter than the Conair InfinitiPro 1875W and substantially better controlled, but the Shark HyperAIR HD120 matched or beat its raw drying time in one direct test at half the price. Against the Shark FlexStyle HD440, the Supersonic wins as a pure dryer while the FlexStyle wins on built-in styling.
