Buying a hair dryer in the UK should be straightforward. It isn't. There are hundreds of options between £15 and £400, and half of them claim to be "professional grade" or "salon quality." Most aren't.

We tested and researched dryers across three price brackets to work out what actually matters and what you can ignore. Whether you want a lightweight hair dryer for everyday use, a salon hair dryer with a cord that reaches the mirror, or a compact travel dryer, these are the six worth buying right now.

Quick summary: The Remington D3198 is the best hair dryer for most people. Under £30, does everything a dryer three times the price does. If you want salon-grade build quality, the ghd Helios at around £130 is the mid-range pick. And if money genuinely isn't a factor, the Dyson Supersonic Nural at £399.99 is in a different league on technology, though not on basic drying performance.

Hair dryer buying guide: what to look for

Here's what actually matters when you're choosing a dryer.

Wattage determines how fast the air heats up and how strong the airflow is. Anything between 2000W and 2300W handles all hair types. Lower wattage (1600W) paired with smart sensors works too, which is the approach Dyson takes.

Ionic technology breaks water droplets into smaller particles on the hair shaft, cutting drying time and reducing frizz. Every dryer on this list has it, including the budget ones. It's not a premium feature any more.

Weight matters more than you'd think. You're holding this thing above your head for 5-15 minutes. A 430g dryer feels completely different from a 1,540g one after ten minutes. We've listed actual weights below, not the "feels light" marketing copy.

Attachments come down to two: a concentrator nozzle (focuses airflow for smooth blowouts) and a diffuser (spreads airflow for curly or wavy hair). If your dryer comes with both, you're sorted.

Cord length is the spec nobody checks until their dryer won't reach the mirror. Budget dryers tend to have 1.7m cords. The ghd Air has 3m. That's the difference between standing where you want and standing where the socket says you can.

Motor type — Budget and mid-range dryers mostly use DC motors, which are lighter and cheaper. Salon dryers typically use AC motors: heavier, but they last longer and produce more consistent airflow. The ghd Air has an AC motor; the ghd Helios uses a brushless DC. Dyson uses a proprietary digital motor that spins faster than either. For home use, both AC and DC are fine. AC motors become worth it if you're drying hair professionally or daily for 15+ minutes.

Heating elements — Ceramic heats evenly and is gentler on hair. Tourmaline-coated elements emit more negative ions for extra frizz reduction. Titanium heats up fastest and holds temperature well, but can run hotter than ceramic. The BaByliss Midnight Luxe uses titanium-ceramic, getting the speed of titanium with the evenness of ceramic. Most mid-range and premium dryers use ceramic or ceramic-tourmaline.

1. Remington D3198 — Best Budget Hair Dryer (Under £30)

The Remington D3198 has sat near the top of Amazon's bestseller list for years. At around £25, you get 2200W of power, ionic conditioning, a diffuser, a concentrator nozzle, three heat settings, two speed settings and a cool shot button.

That's a spec sheet that reads like a dryer costing £60-80. The ionic conditioning reduces frizz and cuts drying time without any product needed. It's built into the grille, not an add-on.

The build is plastic. The 1.7m cord is on the short side. At roughly 580g for the body (around 800g with the cord), it's not the lightest here either. But for what you're paying, none of that is a real complaint.

One catch: Remington offers a 3-year guarantee, but you have to register online within 28 days of purchase. Miss that window and you're on the standard 2-year warranty.

Over 2,100 reviews on Amazon UK with a 4.6-star average. For most people, this is the dryer to buy.

2. ghd Air — Best Professional Hair Dryer for Daily Use

The ghd Air is the workhorse. It has a 2100W professional AC motor, the same type used in salons, and a 3m power cable that actually lets you move around your bathroom.

At around £100-120 depending on the retailer, it's a comfortable mid-range option. The ionic technology works well, and variable power and temperature controls give you more precision than the three-setting approach on budget dryers.

Build quality is noticeably better than the Remington. The removable air filter makes maintenance easier. The design works for both left and right-handed users, which most brands don't bother with.

The problem is weight. At 1,540g, the ghd Air is the heaviest dryer on this list and it's not even close. Genuinely surprised the first time I picked it up. If you have thick, long hair that takes 15+ minutes to dry, your arm will know about it. The powerful motor does mean drying time is shorter, which partly makes up for it.

Comes with a 1-year manufacturer guarantee and a concentrator nozzle. No diffuser in the box. You'll need ghd's separate diffuser attachment (around £29) if you have curly hair.

3. Dyson Supersonic Nural — Best Premium Hair Dryer

The Dyson Supersonic Nural costs £399.99. There's no getting around that number. But what you get for it is different from everything else here.

Sensors inside the dryer measure air temperature 40 times per second and adjust heat output on the fly. It won't overheat your hair or your scalp. Dyson calls this "intelligent heat control" and for once it's not marketing. You can feel the temperature shift as you move the dryer closer to and further from your head.

At 684g and 1600W, it takes a different approach. Lower wattage, but the motor sits in the handle rather than the head, which shifts the balance point. It feels light and even, not top-heavy. The digital V9 motor spins at up to 110,000 rpm, creating fast airflow that dries quickly without relying purely on heat.

It comes in two versions: Straight+Wavy and Curly+Coily, each with different attachment sets. Scalp Protect mode is new to the Nural. It drops the temperature automatically when the dryer detects it's close to your head.

Is it 15 times better than a Remington D3198? No. Nothing is. But if you use a dryer daily and care about long-term hair health, the sensor technology does make a difference you can actually feel. The 2-year guarantee and Dyson's refurbishment programme also help the maths work out over time.

More hair dryers worth considering

These three didn't make the main picks but are worth knowing about.

ghd Helios — Best Mid-Range Alternative

The ghd Helios sits between the Air and the Dyson at around £130-155. It uses ghd's Aeroprecis technology to channel airflow through a brushless DC motor, producing a focused stream at 120 km/h. At 780g it's half the weight of the ghd Air while delivering similar drying performance.

The contoured nozzle focuses airflow for precise styling and ghd claims 30% more shine versus air-drying. If the Air is too heavy for you but the Dyson is too expensive, the Helios fills that gap.

BaByliss Midnight Luxe 2300 — Best Budget Alternative

At £27-35 and only 430g, the BaByliss Midnight Luxe is the lightest and one of the cheapest dryers here. It has 2300W, the highest wattage on this list, with titanium-ceramic technology for even heat distribution. The 2.2m cord is decent and it comes with a 3-year warranty.

The trade-off is build quality. It feels less solid than the Remington in the hand and the attachments are basic. But if weight matters most to you on a budget, it's hard to beat.

ghd Flight+ — Best Travel Hair Dryer

The ghd Flight+ weighs 453g with cord and nozzle, folds in half, and handles both 120V and 240V. Works in the US and EU without an adapter. At around £70-99 it's not cheap for a travel dryer, but it delivers roughly 78% of a full-sized ghd's power.

Auto-shuts off when held too close to hair, has variable speed and temperature controls, and comes with a travel case. If you travel regularly and refuse to use hotel dryers, this is the one to get.

How we chose these dryers

We looked at specs (wattage, weight, cord length, ionic tech, attachments), warranty terms, and price. Then we cross-referenced Amazon UK reviews, hairdresser recommendations, and editorial roundups from Marie Claire, TechRadar, and Woman & Home.

We left out dryers that are frequently out of stock in the UK, models with fewer than 200 reviews, and anything from brands without UK customer service.

Best hair dryer by hair type

Thick or long hair — You want wattage (2200W+) and airflow. The Remington D3198 or BaByliss Midnight Luxe will get through thick hair fastest. Avoid low-wattage models unless they compensate with motor speed, like the Dyson does.

Fine or thin hair — Heat control matters more than power here. The Dyson Nural's sensor technology stops it from frying fine hair. The ghd Air's variable temperature works well too. Don't blast fine hair on the highest setting of a 2300W dryer.

Curly or wavy hair — You need a diffuser, full stop. The Remington D3198 includes one. The ghd models don't (separate purchase, around £29). Low speed, medium heat, scrunch upwards. For more detail, see our guide to hair dryers for curly hair.

Short hair — Any dryer on this list works. A concentrator nozzle helps with precision styling. Don't overspend. The Remington D3198 is more than enough.

Colour-treated hair — Lower temperatures preserve colour. The Dyson Nural's automatic heat adjustment is good for this. Otherwise, stick to medium heat and finish with a cool shot to seal the cuticle.

Frequently asked questions

What wattage hair dryer do I need?

For most hair types, 2000W or above is enough. Higher wattage means faster drying, but also more heat. Fine or damaged hair does better with a lower-wattage dryer that has precise temperature control. Dyson's approach at 1600W with sensors works well for this.

Is ionic technology worth it?

Yes. Ionic dryers release negative ions that break down water droplets on the hair shaft, cutting drying time and static. The result is smoother, less frizzy hair. Even budget models like the Remington D3198 have it, so you don't need to spend extra.

How much should I spend on a hair dryer?

Between £25 and £40 gets you a solid dryer with ionic technology and multiple attachments. Spending £100-160 adds build quality, a longer cord and a better motor. Above £300, you're paying for sensor technology and engineering. The sweet spot for most people is £30-150.

Do I need a diffuser?

If you have wavy or curly hair, yes. A diffuser spreads airflow over a wider area, drying curls without blasting them apart. It keeps curl definition intact and reduces frizz. The Remington D3198 includes one. ghd charges around £29 for a separate diffuser.

What is the best hair dryer for fine hair?

Fine hair needs lower heat and precise control rather than raw power. The Dyson Supersonic Nural adjusts temperature automatically using sensors. The ghd Air's variable temperature control works well too. Don't use the highest heat setting on any dryer if your hair is fine. It causes damage faster than you'd expect.

Is the Dyson Supersonic worth the money?

The Dyson Nural costs £399.99, roughly 15 times more than a Remington D3198. The sensor-driven heat control and lightweight design are real advantages, not gimmicks. But a £25 dryer will still dry your hair perfectly well. It comes down to your budget and how much the technology matters to you. If you dry your hair daily and worry about heat damage, the Dyson earns its keep over years of use.

How long should a hair dryer last?

A budget dryer used a few times a week should last 2-4 years. Mid-range dryers with AC motors (like the ghd Air) tend to go 5-7 years with regular use. Premium dryers like the Dyson come with longer warranties and usually last 7+ years. The most common failure point is the heating element, then the motor. Cleaning the air filter regularly extends the life of any dryer.

Can a hair dryer damage your hair?

Yes, if you use it wrong. Holding a dryer too close to your head, using the highest heat on fine hair, or drying the same section for too long all cause damage. Ionic technology helps by reducing the time you need to spend drying. The cool shot button isn't just for finishing, either. Alternating between warm and cool air reduces heat damage during the drying process.
