The Best Hair Dryers: 4 Compared (and One to Skip)

RBE top pick

Dyson Supersonic Hair Dryer

Check price on Amazon See why it wins Compare all

The Dyson Supersonic is the fast, light, handle-balanced benchmark of the group, with intelligent heat control and five attachments. If its flagship price is a stretch, the Laifen Swift delivers most of the everyday experience, with a 110,000 rpm brushless motor and 100-times-a-second temperature control, for a fraction of the cost.

A great hair dryer is really a balance of three things: how fast it dries, how gently it treats your hair, and how much it costs to get there. We weighed maker specs and owner reports across four models, from a flagship intelligent dryer to a sub-budget workhorse. Two earn a clear buy, one is a genuine "it depends," and one is a skip for most people.

Laifen Swift High-Speed Hair Dryer

Buy it

The smart-money high-speed dryer, with a brushless motor and active temperature control at a fraction of the flagship price.

Best for: Anyone who wants a fast, light, temperature-controlled dryer without paying flagship money.

$$ · mid-range

Why we like it

• Laifen's own 110,000 rpm brushless motor with a stated 22 m/s airspeed, and a motor lifespan Laifen says it tested to 1,000 hours

Shark

Shark FlexStyle Air Styling & Drying System

It depends

A clever dryer-plus-styler combo that's great value only if you'll actually use the styling side.

Best for: People who want to both dry and style at home and will use the curling and volumizing attachments regularly.

$$$ · premium

Why we like it

• Converts between a straight hair dryer and a curved multi-styler, with five attachments in the box (two auto-wrap curlers, two brushes and a concentrator)
• Reviewers report strong results creating volume, waves and curls at home for far less than comparable styling systems

Know before buying

• As a plain dry-it-fast tool it's heavier and more fiddly than a dedicated dryer

We'd skip it

Conair

Conair InfinitiPro Ionic Ceramic Hair Dryer

Skip it

A perfectly fine budget dryer that most people will outgrow faster than they expect.

$ · budget

• Ionic and ceramic tech dries thick hair acceptably fast for the money
• Multiple heat and speed settings cover everyday needs

Know before buying

• Owners describe it as heavy and loud, with more heat on the hair than gentler premium dryers

How we judged the field

We don’t run our own hair lab. Instead we weigh what makers publish and what large numbers of owners report after living with these dryers for months. For this category that means weighing a few things that consistently separate a great dryer from a merely adequate one: real-world drying speed, how well the tool regulates heat to protect hair, weight and balance in the hand, noise, the usefulness of the included attachments, and long-term reliability. Price sits over all of it, because the fastest, gentlest dryer in the world still has to be worth what it costs for how often you’ll use it.

We deliberately picked four dryers that bracket the whole market: a flagship intelligent dryer, a value high-speed dryer, a hybrid dryer-and-styler, and a mainstream budget workhorse. That spread makes the trade-offs obvious.

This is the tool the rest of the field is measured against, and it earns that status. Dyson builds it for fast drying, and the design choice of putting the motor in the handle makes it feel light and balanced rather than top-heavy. Dyson says its intelligent heat control helps prevent the extreme heat that damages hair. Owners often mention how much less tiring it is to use than a traditional salon dryer. Dyson includes five attachments and a 2-year warranty. The downsides are the price, which is several times a capable mainstream dryer, and magnetic attachments that some owners find pop off too easily. But for frequent users who keep a tool for years, it’s the clearest buy here.

The Swift is the value answer to the Dyson, and it copies the parts that matter. Laifen builds its own brushless motor with a stated maximum of 110,000 rpm and an airspeed of 22 m/s, and says it tested the motor to 1,000 hours. Temperature is controlled 100 times a second, with hot, warm and cold settings, a stated maximum of 85°C and a long-press mode that cycles between temperatures automatically. It weighs a stated 407g without the cord, uses negative ion technology to reduce frizz, carries a 2-year limited warranty, and Laifen quotes an average of 59 dB from third-party testing. The limits are what comes in the box and where you can use it: one magnetic smoothing nozzle, two speed settings, and a 120V motor that Laifen says is not dual voltage and cannot be converted with an adapter. For a dryer used at home, it delivers most of the flagship experience for a fraction of the price.

The FlexStyle is genuinely clever: it works as a straight hair dryer and then bends into a curved multi-styler that curls, waves and adds volume with five attachments, and Shark says it measures and regulates temperature 1,000 times a second. Reviewers report strong at-home styling results for far less than comparable styling systems, and beginners tend to find the automatic curl-forming attachments approachable. The catch is that all that versatility adds weight and complexity. As a plain dry-it-and-go tool it’s heavier and fiddlier than a dedicated dryer, there’s a learning curve, and the many attachments are easy to misplace. If you’ll actually use the styling side regularly it’s excellent value; if you just want to dry your hair, you’ll be happier with a straightforward dryer.

There’s nothing wrong with the Conair for the money, which is exactly why it’s a skip for most people rather than a hard no. It’s an ionic ceramic dryer with basic attachments, and it dries thick hair acceptably fast at a tiny fraction of the premium picks. But owners consistently describe it as heavy and loud, it puts more heat on the hair with little regulation, and its reported lifespan is shorter. For occasional use, a guest bathroom, a dorm or travel it’s fine. For a dryer you’ll reach for every day, the step up to the Laifen pays for itself in comfort and heat control.

Dyson Supersonic vs Laifen Swift: which should you buy?

These are the two strongest dryers here, and they are built on the same idea: a small high-speed motor and active temperature control. The Dyson wins on refinement: the motor sits in the handle for balance, it comes with five magnetic attachments, and Dyson’s intelligent heat control is the benchmark. If you dry your hair often and want the best tool with the least effort, and the flagship price doesn’t faze you, buy the Dyson.

The Laifen wins on value. Its 110,000 rpm brushless motor, 22 m/s stated airspeed and temperature control 100 times a second cover most of what makes a high-speed dryer worth having, at a stated 407g and a fraction of the price. It gives up attachments, with only a smoothing nozzle in the box, and it is 120V only. If you want most of the Dyson experience at home and do not need the full attachment set, the Laifen is the smarter buy.

What to look for

• Heat regulation over raw wattage. Sustained high heat is what damages hair. Dryers that measure and limit temperature protect hair better than a high wattage number implies.
• Weight and balance. A lighter, handle-balanced dryer is far less tiring, especially for long or thick hair.
• Noise. Quieter dryers make the daily routine more pleasant; premium models are noticeably calmer.
• The right attachments. A concentrator for smoothing and a diffuser for curls cover most needs; only pay for a full styling kit if you’ll use it.
• Reliability and warranty. Premium dryers cost more up front but tend to last, lowering the true cost per year.
• Match the tool to your habits. Daily user with fragile hair? Go premium. Occasional or backup use? A budget dryer is enough.

Our final take

If you want the best and will use it often, the Dyson Supersonic is the clear pick: fast, light and heat-controlled, with a 2-year warranty. If its price is a stretch, the Laifen Swift is the one we’d steer most people toward, because it delivers a fast, light, temperature-controlled dryer for a fraction of the price. Consider the Shark FlexStyle only if you genuinely want a 2-in-1 dryer and styler, and treat the Conair InfinitiPro as a budget stopgap rather than a long-term daily driver. Buy for how you actually dry your hair, and any of the top three will serve you well for years.
