Straight hair will never go out of fashion, neither will the best hair straighteners you can use to achieve it.

That means you no longer have to pay premium prices to achieve healthy poker-straight tresses or cascading waves.
Thankfully, we’ve tested a wide range of hair straighteners to help you find a suitable option, no matter your budget. Modern hair straighteners boast adjustable heat settings and protective technology that’s designed to reduce damage. The most versatile models can even create a range of styles from poker-straight to loose curls and beachy waves.

How we test hair straighteners
At Expert Reviews, we know that hands-on testing delivers the best and most complete information about a product. As such, we personally test all the hair straighteners we review, using each model as recommended on dry hair. Where applicable, we assess the various heat settings and, where straighteners are recommended for a particular hair type or use, we test on that hair type to ensure we’re making an accurate recommendation.

As well as recording the time it takes each tool to heat up to 180ºC from cold, we also measure how quickly we’re able to straighten a full head of hair, noting the length and texture of the hair on which we’re testing. We then evaluate the overall ease of use of the straightening tool and how it feels in the hand. Battery life is also timed, if applicable in cordless models.
We then provide information on the finish and feel of the hair after straightening, how well straightened styles last over the course of a typical day of wear – and, finally, confirm the weight and dimensions of the tool.

The best hair straighteners to buy in 2025, according to our tests
1. GHD Platinum Plus Styler: Best hair straighteners overall
Price when reviewed: £239 | Check price at Amazon

- Great for: Smooth, shiny, healthy results
- Keep in mind: More expensive than other models
The Platinum Plus is GHD’s premium offering, with floating ceramic plates designed to deliver optimum heat for your hair type. They styler maintains that optimum temperature using intelligent heat technology that measures and adjusts it constantly while styling. The result is even heat across the plates that won’t scorch the hair, leaving hair looking glossy and feeling healthy.
During our tests, the smooth gliding plates and even heat distribution allowed us to achieve smooth straight sections of hair in one pass. Furthermore, we found that the wishbone-shaped hinge reduced the risk of catching or snagging hair as we styled. The Platinum Plus straightened our reviewer’s curly hair in around half the time of other straightening tools, producing shinier tresses with less breakage.
We also rate how the GHD Platinum Plus Styler looks. Available in both white and black, there’s also a limited-edition colour – alluring Jade.

Key specs – Plates: 2.7cm ceramic plates; Maximum temperature: 185°C; Voltage: Universal; Cord length: 2.7m swivel cord; Automatic shut-off time: 30 minutes; Warranty: 2 years
2. Remington Shine Therapy Straighteners: Best budget hair straighteners
Price when reviewed: £29 | Check price at Amazon

- Great for: Shiny results
- Keep in mind: Basic build quality
If sleek and shiny tresses are your go-to look, you’ll need straighteners that can easily create a poker-straight style without damaging the health of your hair. These Remington straighteners use ceramic plates infused with conditioning properties, such as Moroccan argan oil and vitamin E, to keep your hair looking and feeling its very best.
When we tested the Remington straighteners, its floating plates ensured an even pressure and grip on the hair, which helped us to glide the tool down the hair sections smoothly. This is impressive considering the Shine Therapy’s pocket-friendly price point.
There are nine heat settings, which made it easy for us to select the correct heat for our hair type and texture. We also found it easy to switch between the various temperatures, meaning you can use a recommended 180°C for the bulk of the hair and a cooler setting for the thinner, more fragile front sections. The straighteners heat up in just 15 seconds and feature automatic switch-off after one hour.
Key specs – Plates: Ceramic plates enriched with micro conditioners; Heat settings: 9; Maximum temperature: 230°C; Cord length: Swivel cord; Automatic shut-off time: One hour; Warranty: 180 days
3. Revamp Progloss Touch Digital: The best straighteners for fine and damaged hair
Price when reviewed: £100 / Check Price at Revamp

- Great for: Low heat styling, styling wigs and extensions
- Keep in mind: Pricier models give a glossier finish
The Revamp Touch Digital straightener stands out thanks to its exceptionally wide temperature range, from just 80°C at the lowest setting to 235°C at the top. The coolest setting is gentle enough to style synthetic hair, making it ideal for wigs, extensions and hairpieces, while temperatures of around 150°C are best for fine or fragile hair that’s heat or chemically damaged. You can increase or decrease the heat in 5°C increments, making it easy to pinpoint the perfect temperature for your hair.
The intuitive touch controls make it simple to adjust the temperature. In our tests, the clear colour indicators (yellow for low heat, orange for medium and red for high) made it easy to check if we had the straighteners on the right setting, even when we were looking in the mirror. There are also three preset temperature modes tailored to fine, medium, and thick hair, which can be activated using the “Hair Mode” button next to the main controls.
We were also impressed by the Touch Digital’s fast heat-up time, reaching 180°C in under 20 seconds. It has an intelligent heat sensor that continuously monitors the temperature to prevent overheating and, after every stroke, the irons heat straight back up. This meant we didn’t need more than one pass to straighten each tress. We can easily recommend this fast and easy-to-use pair of straighteners for fine, brittle or artificial hair.
Key specs – Plates: Ceramic plates enriched with keratin and oils; Heat settings: 32 (plue three pre-set modes); Maximum temperature: 235°C; Voltage: Universal; Cord: 3m; Automatic shut-off time: 60 mins; Warranty: 3 year
4. Dyson Airstrait: Best wet-to-dry straighteners
Price when reviewed: £450 | Check Price at John Lewis

- Great for: healthy wet-to-dry styling on all hair types
- Not so great for: achieving curly styles
We always advise caution with wet-to-dry hair straighteners because the hair is more fragile when wet. Using any heated plates can scorch the hair more easily, causing excessive heat damage over time. The Dyson Airstrait, however, is the first hair straightener that doesn’t use any heated plates whatsoever, and we have to say it’s mighty effective.
Instead of heated plates, the Airstrait uses two precisely angled jets of air to press the hair into a straight position, drying it as it goes down the hair shaft. Since the malleable hydrogen bonds in the hair’s structure are set into a straight position as the hair dries, the Airstrait gives longer-lasting straight styles at lower temperatures. And, since no high heat is used, this is better for your hair than traditional straighteners.
In our tests, we got our hair from freshly washed and dripping wet to bone dry, straight and silky in under 15 minutes. We tested the straightener on curly, wavy and thick hair, and each gave the same sleek results. These results lasted flawlessly over three days of humid weather and gusty winds until our next wash day – mighty impressive for any hair styler.
Bear in mind, though, that the Dyson Airstrait is incredibly expensive, and it was incapable of creating much-loved straightener curls in our tests. However, it would be a sage investment for those who want to straighten their hair regularly without damaging it with scorching plates.

Key specs – Plates: None; Maximum temperature: 150°C; Voltage: UK; Cord length: 2m; Automatic shut-off time: 3-second pause detect; Warranty: 2 years
5. GHD Chronos Max: The best wide-plate straighteners for long and thick hair
Price when reviewed: £299 | Check price at John Lewis

- Great for: Wide plates, fast, glossy finish
- Keep in mind: One heat setting, can’t curl
Wide-plate hair straighteners can straighten larger sections of hair compared to standard-width straighteners, which makes them a godsend for anyone with very long or thick hair. GHD’s latest offering, the GHD Chronos Max, upgrades its previous wide-plate styler for ultra-fast styling with a super-glossy finish. The Chronos Max heats up in under 30 seconds and, once hot, GHD’s HD motion-responsive technology adjusts the heat based on your movements to ensure you get straight hair in just one pass. This worked brilliantly in our tests, saving us time on styling, and limiting heat damage.
The 4.2cm-wide high-gloss plates have thinner edges that allow you to style closer to the root for smooth results from root to tip. It was able to effortlessly catch the finer hairs at the top of my curly hair, which is mighty impressive. Furthermore, there was zero snagging during styling and I found my hair looked noticeably shinier than usual after styling, with results that lasted all day and into the next. It’s a sensible investment for those who want to keep unruly locks healthy, even with regular styling.

Key specs – Plates: High-gloss floating ceramic; Heat settings: One; Maximum temperature: 185°C; Voltage: Universal; Cord length: 2.7m; Automatic shut-off time: 10 minutes; Warranty: 2 years
6. BaByliss 9000 Cordless Straighteners: Best cordless hair straighteners
Price when reviewed: £180 | Check price at Boots

- Great for: Cordless operation, full-size
- Keep in mind: 30 minute battery life can be limiting
The BaByliss 9000 is a cordless straightening tool with floating ceramic plates that glide over the hair. In our tests, we found it made light work of straightening all hair types and textures, while the slim, curved body of the tool was perfect for creating straightener curls. Since the tool is cordless, we found it super-easy to wrap the hair around at any angle around the head, without getting into a tangle.
These straighteners offer three heat settings – 160°C, 180°C and 200°C – and heat up within seconds, so you won’t waste any charge in the heat-up time. The battery takes three hours to charge for 30 minutes of use, which will be sufficient to style most types and lengths of hair. We found the floating ceramic plates heat up evenly during use and it’s easy to operate using a single button that controls both power and heat selection.
We also like that these are ideal for styling on the go, thanks to a handy heat-resistant travel bag. So, if you’re in the market for a cordless straightening tool that can handle both straight and curly styles with ease, the Babyliss 9000 is our recommendation.
Key specs – Plates: Floating ceramic; Heat settings: Three temperature control options; Maximum temperature: 200°C; Voltage: Universal; Cord length (charging cable): 1m; Automatic shut-off time: 15 minutes; Warranty: 2 years
7. Nicky Clarke Frizz Control Straighteners: Brilliant affordable straighteners
Price when reviewed: £40 | Check price at Amazon

- Great for: Affordability
- Keep in mind: Fewer heat settings
Hairdresser Nicky Clarke has a range of budget-friendly hair styling tools that deliver great results and these straighteners are no exception. The plates are coated with both ceramic and tourmaline, and have ionic technology to lock in moisture. There are five heat settings from 150ºC to 230ºC, making the straighteners good for a range of hair textures including both fine and thicker hair.
The Frizz Control Therapy straighteners heat up in 60 seconds and have a 3m swivel cord, which makes it easy to manoeuvre the tool around the head to reach any tricky parts of the hair. In our tests, we found they moved smoothly over our hair, leaving it super soft and shiny. Especially for the price, these straighteners give good results on all hair types – including dry or frizz-prone.
Key specs – Plates: ceramic/tourmaline; Heat settings: 5; Maximum temperature: 230ºC; Cord length: 2m; Automatic shut-off time: 60 minutes; Warranty: 6 months
8. Cloud Nine Contouring Iron Pro: Best hair straighteners for curly and straight styles
Price when reviewed: £299 | Check price at Lookfantastic

- Great for: Creating multiple styles with ease
- Keep in mind: Expensive
Hair straighteners aren’t just good for straight styles – they can also be used to curl hair if you use the right technique. However, it’s incredibly difficult for some people to master the art of straightener curls and that’s where the Cloud Nine Contouring Iron Pro comes in.
We really rate this innovative design, which has two interlocking curved plates to help to guide the hair into big bouncy curls with a simple turn away from the face. This shape, paired with the floating plates, meant that our hair moved beautifully through the iron, without any snagging or pulling. The iron can also be used to achieve perfectly straight looks – just drag it straight down without turning it.
The Contouring Iron also has an impressive temperature range, with 11 temperature settings between 100°C and 200°C. There’s also a “Revive” mode, which fixes the temperature at 150°C but uses micro-vibrations in the plates during styling to help create longer-lasting styles with low heat. This is a step up from the Cloud Nine Original Iron, featured below, and worked remarkably well in our testing. There’s no getting around the fact that this is an expensive curling iron, but it’s the perfect all-in-one styler for those willing to splash out.

Key specs – Plates: Floating; Maximum temperature: 200ºC; Voltage: 100-240V; Cord length: 3m; Automatic shut-off time: 30 minutes; Warranty: 3 years
9. BaByliss 3Q Hair Straighteners: Best Cloud Nine and GHD Alternative
Price when reviewed: £52 | Check price at Boots

- Great for: High quality features at a lower price
- Keep in mind: Buzzing noise
BaByliss has a history of producing must-have hair tools that dates back to the 1960s, and many of its inventions – including the Perfect Curl and Big Hair – are cult favourites.
We love how the 3Q hair straighteners heat up quickly and transform frizz into fabulous smoothness. In addition, they even protect damaged hair with the aptly named Protect button, which switches temperature accurately to one suited to your hair in just a few seconds. In fact, the BaByliss 3Q Hair Straighteners boast many of the features of their high-end contemporaries, using sensors to work out the correct temperature for your hair, maintaining heat and leaving a salon-shine finish.
If you have more delicate or damaged hair, then the lower temperatures will certainly help keep your hair healthy. The 3Q straighteners aren’t the quietest in operation and sometimes make a rather disconcerting buzzing noise but they represent good value for money in the middle of the market.
Key specs – Plates: 2.8cm quartz-ceramic plates; Heat settings: 12 digital options; Maximum temperature: 235°C; Cord length: 3m swivel cable; Automatic shut-off time: 72 minutes; Warranty: 5 years
How to choose the best hair straighteners for you
What size heating plates are best for you?
Plates of around one inch are perfect for most types of hair and far better for curling and shaping the hair. Short hair will get on best with thinner plates because they allow you to get close to the root.
The best hair straighteners for thick hair are those with large, wide plates. However, plates that are over an inch wide make it more difficult to achieve curly and wavy styles.
Which materials and coatings are best on the heated plates?
Straighteners with non-metallic plates – such as ceramic or tourmaline – typically heat more gently and evenly, producing a shinier finish. Tourmaline plates specifically achieve optimum results at lower temperatures, resulting in less heat damage with regular use.Plates might also be coated in titanium, which heats up very quickly. This not only cuts the overall time required for styling, it reduces the amount of time that the hair is exposed to heat.
What other features should you look out for?
Plate size and material are of most importance when it comes to choosing hair straighteners, but there are some other features to consider, too.
- A long cable is a godsend if you don’t want to be stuck next to the plug socket, especially if there isn’t a socket close to your mirror.
- If you can, get a rotating swivel cord, too. Some swivel through 360-degrees, which can make all the difference when attempting to style hard-to-reach areas.
- Straighteners with curved edges are great if you want to create curls, waves and flicks as you can shape your hair around the body of the iron.
- Some irons automatically switch off after a certain period of inactivity, which greatly reduces the risk of accidental fire and is a must for forgetful types.
- A quick heat-up time of under 30 seconds will be welcome for those who are often in a hurry.

How do you use hair straighteners?
Hair straighteners are simple to use. Simply clamp a section of hair between the two plates of a straightener and drag the iron down the hair’s length. Follow these steps to ensure you get the best results every time:
- Always ensure hair is completely dry before straightening
- Spray hair with a heat-protective product before you begin styling to keep heat damage to a minimum
- Section hair prior to styling, starting with the bottom layers of hair at the nape of the neck, working your way up to the crown in small sections
- Straighten the hair in inch-wide sections for the best results
Depending on the thickness of your hair and the level of practice you’ve had, a straightening routine can take anywhere between 10 to 30 minutes.
Which temperature setting should you use?
Most manufacturers recommend styling at 180˚C for the healthiest finish. However, you’ll achieve better results on textured hair at temperatures up to 210ºC. Those with fine, damaged or colour-treated hair should stick to lower temperatures of around 165ºC.
Exercise caution when choosing a heat setting, since high heat can frazzle and even break fine hair. The keratin protein that makes up your hair starts to melt at 233˚C, so avoid going up this high.
How do hair straighteners work?
So how does heat styling cause the natural shape of hair to change? Heat causes the hydrogen bonds in the hair to break. Once a straightener is passed over the hair, the hair cools and the hydrogen bonds re-form into a new, straight position. If the hair is wrapped around the tool, rather than held straight while cooling, then the hair will take on a loose curl shape instead.
