Whether for poker-straight results, curls or waves, these are the hair tools to buy
Hair straighteners have evolved significantly since their first 1909 flat-iron iteration (thank goodness). Today, there are myriad streamlined cordless and corded designs with adjustable heat temperatures, ceramic plates, powerful airflow features and so on.
Indeed, the popular beauty tool has taken many forms over the years and at one point it was essentially a hair steamer, with water needed to boil inside before roughly sliding through your hair – yikes. Aside from hairdryers, straighteners were the first heated beauty tool to break into the beauty business, before the ever-popular Dyson airwrap (as well as the affordable alternatives to follow), curling tongs and heated rollers.
The best hair straighteners can be used on all hair types, from fine to thick hair, curly, wavy and straight – yes, straight, as you can tame any frizz with a straightening iron, soften the ends, or create mermaid waves, and even curls with the tongs.
I’ve been busy testing all sorts of hair straighteners, and have whittled them down to the top tools worth investing in. Keep scrolling to find out how each model fared.
For more than a month, I have tested numerous hair straighteners from leading brands, including ghd, Dyson, BaByliss, Remington, Nicky Clarke and many others.
Prior to picking up each straightener, I washed my hair, as per my usual haircare routine, and dried it thoroughly with a hairdryer, which often leaves my hair frizzy and unruly. I sectioned my hair and spritzed it with a heat protectant spray, to help protect against damage. I then worked through my long hair with the straighteners, section by section, and finished with a nourishing oil on the ends.
I only deviated from this routine when using wet-to-dry stylers, such as ghd’s duet creation and the Dyson airstrait, which can be used to dry and style damp hair. In those instances, I washed my hair and let it loosely air dry before using the hair tools, as they can’t be used on sodden locks.
I noted how easy the straighteners were to use, if they were lightweight and easy to hold, how quickly they heated up and cooled down, as well as considering additional accessories or features. If the straighteners had adjustable heat settings, I tested the entire spectrum, for a thorough insight into each tool’s features and efficacy.
I have sworn by ghd’s original styler straighteners ever since they launched in 2001, and though they have undergone some slight modifications over the years, it’s safe to say these straighteners are durable, stand the test of time, hold a style in place for hours, even in humid weather, and are therefore my go-to top pick.
While the ghd straighteners do not have an adjustable heat setting, as they only function at a constant 185C heat, the single-zone technology ensures the ceramic plates provide constant and even heat to effectively style your hair in one glide. I can create poker-straight hair in minutes, or add waves and curls to my hair, courtesy of the curved edges.
What I love is they are super quick to heat up, easy to use, especially for those who are not so savvy when it comes to styling their strands and are suitable for all hair types, including fine and thick, wavy and curly locks.
The original styler weighs just 828g, which is particularly good news for those with longer lengths, and features an auto shut-off function that kicks in after 30 minutes if the device isn’t being used.
I have a soft spot for the Nicky Clarke airstyle pro (£249.99, Nickyclarke.com), so, I had high expectations for these frizz control straighteners, which can help you create a super-sleek hairstyle in minutes.
With five temperature settings (up to a maximum of 230C), and long and slim tourmaline-coated plates – which use negative ions to seal and protect each hair shaft – this tool easily straightens and tames frizz and flyaways, hence the name.
However, I found the lock feature stiff and temperamental, as it often opened when it should have been shut. Another bugbear is the temperature settings on the top of the barrel are labelled one to five, instead of showing the temperatures in Celsius like other tools do. I gathered that one is the 150C starting point, five is the maximum heat, and I assumed the settings in between must be odd numbers increased by 20C. I love a hair tool with adjustable settings, but I can’t help but question whether the maximum 230C temperature is too high.
Despite these niggles, the straighteners heat up in seconds, are easy to use, and straightened my long hair effectively, which, combined with its relatively affordable price tags, makes these straighteners ideal for shoppers hunting for a bargain pair of straighteners.
I have used Drybar’s half shot small round brush (£125, Lookfantastic.com), which works effectively to dry and style my hair, so, I was hoping the tress press straighteners would be just as impressive, and they did not disappoint.
This multipurpose tool gets my seal of approval because it is a compact, yet powerful, straightener with floating narrow plates, which measure an impressive 1in in width, for precise styling.
The infrared technology works to heat the hair from the inside out, reducing frizz while adding shine to your hair. The curved edges also help to create beach waves, ringlets and straight dos with soft ends.
These straighteners are suitable for all hair types; the adjustable heat settings enable every user to tailor their styling session to their needs. The titanium plates are particularly suited to thicker hair, while the narrow plates are often useful for short lengths or getting to the roots.
This is the first pair of infrared hair straighteners I have used, and I was impressed by how straight and glossy my hair looked within minutes.
It releases negative ions onto the hair shaft, to protect strands while minimising frizz. Meanwhile, the titanium floating plates distribute heat evenly, and glide through all hair types, for a straight and glossy finish.
These straighteners boast 12 heat settings (from 120C to 230C) that appear on the LCD screen and the tool remembers the temperature of your last styling session to save you time.
This tool was easy to use and features a lock switch to protect the tool (and curious little fingers). It also comes with a heat-resistant travel case, which unravels into a protective mat onto which you can place the straighteners when in use. In comparison with other designs, these straighteners are not the lightest (weighing 1.38kg, though, I wouldn’t describe them as heavy, by any means), and are best suited for straightening rather than curling, because of the jagged edge of the barrel.
These straighteners are super lightweight, streamlined and fractionally shorter than other designs, which makes them great to take with you when you’re on the go. The ergonomic handle with the matte finish and thumb grove also made this model easier to hold while I styled my long hair. After using them, I was left with a silky-smooth, frizz-free finish, which lasted on a humid summer’s day – much to my surprise.
Panasonic is known for creating hi-tech designs, and these straighteners are no different; they release nanoe atomised water particles from the air holes on the sides of the plates, which claim to be more hydrating than typical ions. This feature also protects the hair from heat damage; maintains the moisture and natural oils in the hair, while simultaneously minimising flyaways; and achieves a high-shine finish, which was evident in my results.
This design is super easy to use – the heat settings are adjusted using buttons inside the straightener, which light up instead of showing on an LCD screen and can be used on all hair types (whether you’re straightening or curling your strands). While it is quick to heat up and achieves 10 out of 10 results, I noticed a soft humming sound from the straighteners, which was my only bugbear.
Beauty Works offers an array of heat tools and hair products, including an ever-expanding Molly-Mae Hague collection. After putting these straighteners to the test, I was pleasantly surprised. I can be sceptical of lightweight, and plastic-feeling hair tools but I stand corrected. These straighteners are easy to use, for straightening and curling my hair; they heat up in an instant; and the set features a glove to protect your fingertips, as well as a paddle brush and pink travel pouch, which is a huge pull factor.
These straighteners operate across the broadest heat temperature spectrum I have seen (80C to 220C, with 5C increments). To adjust the heat, simply rotate the dial at the base of the straighteners. This sounds easy but, embarrassingly, it took me a while to realise how to tailor the settings, as it is not signposted. This dial’s location also means it could be knocked easily while the straighteners are in use, so, you could end up adjusting the heat unintentionally.
BaByliss’s super styler ticks a lot of boxes: it has adjustable heat settings (up to 200C), it’s suitable for all hair types and lengths and can create straight or wavy styles.
The ergonomic design features BaByliss’s signature micro heating matrix technology, which utilises 2,500 micro heaters fitted on the surface of the ceramic plate, to ensure even heat distribution across every strand. The in-built microprocessor monitors the temperature of each microheater when the hair tool is firing up (or cooling down), for optimal user safety and efficient styling. Similar to ghd’s original styler, the Babyliss straightener features curved edges, to help achieve a soft finish, without any indents on the hair, particularly when curling, for a smoother finish.
One slight niggle is the heat gauge is fitted on the top of the straighteners and didn’t state the exact temperature in degrees, which would make it easier to prevent heat damage, as numerous heat options are available. It was only through reading the instructions I came to learn the further away the indicator is from the on/off button, the hotter the temperature.
Ghd is known for how powerful and compact its hair tools are, as well as how quickly they fire up. Within seconds, the straighteners were ready to use, and I was conscious not to waste any time, as this cordless design has a run-time of 20 minutes after a two-hour charge. While this was sufficient styling time for my fine yet long hair, if you have super long or thick hair, these portable straighteners may not be the most viable for you. Admittedly, you can recharge this hair tool by plugging the USB into your phone, computer or mains supply, though, you can’t use the straighteners while they’re charging, which could delay your styling session.
A feature found in most ghd products is the dual-zone technology in the ceramic plates, which provide an even distribution of 185C heat, to deliver a sleek and glossy finish; tame frizz and flyaways; and help to create a range of long-lasting hairstyles.
Thanks to being remarkably compact, this model is perfect for taking on the go. This bundle includes a heat-resistant travel pouch, in which you can safely store your straighteners just a few seconds after you’ve finished using them.
This hair tool has garnered more than 2,000 glowing reviews, and we get the hype. The original iron is lightweight and has adjustable temperature settings to suit every hair type and style, so you can achieve a sleek straight do or tight curls easily. The plates are infused with the mineral sericite, which strengthens and protects the hair, while also contributing to a smooth and shiny finish.
The lightweight plates are quick to heat up to temperatures of more than 200C, but the highest heat setting is listed as “high”, which is too vague for my liking – especially as I’m conscious of using excessive heat on my damaged hair – is it 205C, 230C or higher? This needs to be specified, in my opinion, as there is a difference and it could be detrimental to anyone’s hair.
As the straighteners are heating up, a light flashes on the desired temperature you select but it isn’t until all the temperatures prior are lit that the tool is ready to use, which is a nifty feature when you understand it, though slightly confusing at first. A slight bugbear is the on/off switch is on the inside of the straighteners, opposite the temperature gauge, so, take care when adjusting the settings, as the inner area gets hot.
Having said that, I was impressed by how efficiently these straighteners worked when it came to styling my hair – both for super-sleek straight dos and soft waves. I just kept the temperature to a safer 180C.
Remington has catered to everyone’s needs, whether you’re hunting for straighteners specifically designed for short and fine hair or thick and long tresses. The brand’s extra-wide plate straighteners (also included in this round-up) and the extra-slim hair straightener are both from the pro ceramic range, which means they share the exact same features despite the different plate sizes.
The extra-slim plates make it easy to style short and fine hair, as the actual ceramic plates measure just 1cm in width, which makes it easy to straighten the roots, the back of the head, and short layers. The ceramic ultra-coating on the plates worked wonders, too, leaving my hair looking smooth and straight, but, to achieve a poker-straight finish, I needed to use hotter temperatures than I would have liked.
These straighteners heat up quickly, feature adjustable temperature settings, which are displayed on the LCD screen, and a nifty lock feature at the base near the cord. However, the slimline plates took a little longer to sweep through sections of my long hair, which would be the same for those with thicker locks. Although the finish was sleek, the wider design suited my hair better. If you are looking for a more affordable version to ghd’s mini professional styler, though, this is your best alternative.
This model is a new addition to the brand’s ever-expanding hair tool range. I managed to get my hands on one and was impressed by the infrared technology, which worked to straighten and tame my frizzy mane in one swoop.
This tool boasts extra-large plates, which are best suited for thicker hair or long lengths, and they heat up rapidly, so you can get styling in seconds.
The infrared and ion technology worked to style and de-frizz my hair, as the ions attach to each hair shaft to minimise any static, which, combined with the ceramic and keratin-coated plates, achieves a smooth finish and long-lasting hold.
These straighteners boast four adjustable heat settings, flexible plates, a lock feature, as well as intelligent heat control, to ensure even heat distribution and a smooth run along the hair shaft, to avoid any breakages. What I also love is this set includes a bag in which to house your hair tool and a cloth to clean the surface.
This is a smaller version of the classic ghd original styler. Boasting a 40 per cent slimmer plate than the original, this tool is perfect for use on shorter lengths and fine hair.
The ceramic floating plates heat up in an instant, glide through the hair seamlessly without catching on any strands, and are super easy to use, with one heat setting fired up the moment you press the ‘on’ button. I can’t fault the quality of these straighteners but they are better suited for shorter hair lengths (from 1.5in), as it will take far too long to straighten every segment of long or coarse locks.
A lightweight pair of straighteners with wide plates is essential for those with thick or long hair, as it can style a wider section of hair quickly and efficiently, as well as prevent arm strain. These Remington straighteners are fitted with ceramic ultra coated plates, which measure 45mm in width and 110mm in length, and achieve a silky smooth finish. The design features an adjustable heat control (up to 230C), which shows up on the digital screen and it heats up in mere seconds.
These straighteners are suitable for all hair types but I recommend using them on mid-lengths and long hair, as well as thick locks, to cut down the duration of your hair styling session, and to avoid running hot plates over the same section of hair numerous times, which can contribute to heat damage and breakage. While the plates make for speedy styling, creating a style other than a straight do is nearly impossible.
Dyson released its airstrait in the UK in February 2024 – almost a year after its stateside release – and it has been a ground-breaking success. The two-in-one hair tool features a hyperdymium motor, powered by a 13-blade impeller, to provide a powerful airflow, to dry and style the hair with minimal heat damage.
An unexpected, yet essential, feature is the PRCD (portable residual current device) plug, which you need to test and reset every time before using the straightener, due to this being a wet-to-dry electric hair tool. This plug is cumbersome, however, so, if you have a skirting board near the mains supply, it can be difficult to fit flush.
Admittedly, I was sceptical about how my frizzy locks would fare, and if the style would hold during a humid summer’s day – especially with a maximum styling temperature of 140C. The Dyson airstrait effectively dried and straightened my hair somewhat, with the overall finish being straighter than if I let my hair air dry. Overall, it achieved more of a soft-straight blow dry than a poker-straight do. So, if you have curly hair, this may not provide the same dead-straight finish, or long-lasting hold you’d get from a pure straightener.
Though the airstrait is slimline, the wide plates made it hard to reach the roots, plus the airflow only blows in one direction. Considering I alternate the hand I use, or angle, to straighten certain areas, it meant the tool was upside down and blew out the segment I wanted to style.
I am impressed by the ingenuity of Dyson’s airstrait, and though I can’t fault its multifunctionality as a hair tool generally, in the straightener category specifically, there is some room for improvement.
Ghd changed the hair tool world when it launched its innovative two-in-one hot air styler in 2023, which can be used on damp (not wet) or dry hair, making it a go-to multipurpose, time-saving and efficient hair tool.
The brand’s unique air-fusion technology calls on the best of ghd’s design features: it uses high-power airflow to safely dry damp hair, and combines with snag-free floating plates, for a sleek style.
I was sceptical about using a straightener on wet hair, but ghd proved me wrong. The heated floating plates boast built-in sensors to assess your hair’s needs and texture, and adjust the heat accordingly, to prevent sizzling your locks. While my hair went from scraggy damp mop to a dry, straight do in minutes, I found it difficult to switch between drying and styling at first, so, I recommend drying your entire head of hair before going back to style each segment.
For me, the drying option was not enough to straighten my hair, though my tresses were significantly less frizzy, compared with using a hairdryer or the Dyson airstrait. The shine shot achieved a straighter and glossy finish, and refreshed day-two hair, but this was not as powerful as a sole ironing tool, which I often turn to for a poker-straight finish. Like most ghd straighteners, the hot air styler features an auto-sleep safety feature, after being inactive for 30 minutes.
This tool is more cumbersome than other streamlined ghd straighteners, purely because of the wide plates, which made reaching the roots of my hair slightly difficult as well as leaving them slightly greasy. It would make using this tool on shorter hair slightly problematic, too. There is some noise from the device when drying hair but it is significantly quieter than using a hair dryer.
There are various styles of straighteners to shop, from slimline to wider plates, ceramic and titanium designs. Some are infused with ionic technology or keratin to treat damaged hair or for an ultra glossy finish. Plus, there has been a rise in hair tools that use air flow instead of extreme heat.
Knowing what the best hair straightener is for you depends on your hair type. Ghd ambassador Patrick Wilson has shed some light on the debate: “The most important features to look for when buying hair straighteners are, of course, how well they perform and the temperature range. You want them to be able to do the job but also not damage your hair.”
Those with short hair may prefer a slimmer straightener, to run through short layers from the root along the hair shaft, while those with thick hair may prefer wider barrels, to cover more ground and to speed up the styling session.
Damaged hair will benefit from straighteners infused with keratin treatment or other protective features, to help nourish broken strands and protect against further damage. Meanwhile, those with frizzy locks may find ionic technology helps to tame any fuzz or flyaways.
Some straighteners feature adjustable heat settings, which is recommend for all hair types, as it gives users more control over the tool, to suit their hair type and to avoid heat damage – using extreme temperatures over 185C is not advised.
Straighteners can come fitted with narrow, wide, short or long plates, and knowing which style is right for you depends on your hair length and density.
Typically short cropped dos, as well as fine hair, will benefit from slimline straighteners, to get into those hard-to-reach areas with ease. Those with thick or curly hair, or longer lengths, will find their hair takes longer to straighten, which is why wider plates, or dual-purpose straighteners that dry and style simultaneously, are often preferred.
If you opt for straighteners with a hot plate instead of air flow, you will find ceramic or titanium plates are the popular options to choose from. But what is the difference? Wilson explains: “Ceramic flat irons take longer to heat up and work by heating your hair from the inside out, while titanium/airflow straighteners heat up immediately and heat your hair from the surface.”
In a nutshell, a ceramic iron is generally deemed better for finer hair, while a titanium plate is most effective on coarse or thick hair.
Some straighteners feature adjustable temperature settings but others are set at one fixed temperature. The latter can make the tool easy to use, as it minimises the hassle of trying to find a program best suited to your hair type and needs. According to Wilson, a temperature of 185C is considered the “optimum styling temperature” for all hair types, which most hair tools will reach, whether it has adjustable settings or not.
If you opt for straighteners with adjustable heat settings it is advised those with dyed, brittle, fragile or fine hair use the lowest setting at around 100C to 185C, while thick or coarse hair can work with higher temperatures, but always use heat protection sprays, if so. Some straighteners with adjustable heat settings can reach intense temperatures of 230C, which is to be avoided, especially for fine, short and damaged hair, as it can lead to irreversible hair damage.
There is some cynicism over wet-to-dry tools and their efficacy but Wilson says: “Wet-to-dry stylers are extremely safe and incredible time savers. The optimal styling temperature is lower than the heat you would normally use to dry your hair, so it’s also saving your hair from any damage.”
Straighteners have come on leaps and bounds over the years, as many designs are feather-light, compact, and easy to take travelling. If you are looking for a lightweight and compact pair of straighteners to take on the go, a cordless design, such as ghd’s unplugged, ticks all the right boxes. If you have long or thick hair, you will want a lightweight design even more so, to avoid any arm ache during your styling session.
Any heated styling tool can damage hair, especially if your tresses are already lacking in moisture and protein. This – combined with external aggressors such as chlorine, chemical treatments and over- or under-washing – can leave your hair looking and feeling lacklustre.
The best preventative measure you can take is to always use a heat-protectant spray before blow-drying, curling or straightening your hair. This is because the spray will add a protective layer that acts as a shield to absorb the heat and leave your locks undamaged.
Another step you can take to protect your tresses is to only straighten hair that is completely dry. Hair is at its most fragile when wet – if you’ve ever attempted to use a heat styler on damp hair, it’s likely you’ve heard your strands sizzle, which should tell you all you need to know. Doing so can increase breakage, frizz and even make your hair’s natural texture coarser.
If you want to curl your hair with your straightener, steer clear of the wide flat irons and opt for a slimmer model instead, as it will be easier to wrap your hair around the tool, to create curls. To curl your hair, clamp a strand of hair inside the straightener (smaller strands for tighter curls, bigger strands for a more wavy look), then wrap the ends of your hair over the straightener while either twisting the iron towards you or away from your, depending on the kind of curls you want. Then, all you have to do is hold it there for a few seconds before gently pulling the straightener down until reaching the ends of your hair, at which point you can let go of your grip.
Having tested the ghd original (£139, Lookfantastic.com), unplugged (£224.25, Lookfantastic.com), mini (£149, Amazon.co.uk) and duet (£341.10, Lookfantastic.com) here, as well as reviewing the entire ghd straightener range in a separate guide, the ghd original and platinum+ (£199.99, Very.co.uk) straighteners came out top among the brand’s offering, thanks to their high-quality ceramic plates, ease of use and fast heat-up time.
Despite having long hair, I prefer a thin barrel to reach my roots, as well as the back of my head easily, and tame any stray hairs. A slimline design with curved edges is the ideal combination for me, as the tool becomes a multifunctional two-in-one straightener and curler, which saves space in your luggage, and those all-important pennies.
With those factors in mind, ghd’s original styler, along with the Silk’n, DryBar, Cloud Nine, Panasonic and Beauty Works straighteners ticked more of my boxes. They styled my long hair quickly and easily without the need to repeatedly go over the same segment. Ultimately, ghd’s original styler gets the gold star from me – I have used it for more than 20 years as my go-to for sleek, frizz-free and poker-straight styles in seconds. DryBar is a close second, as it boasts the same slim and lightweight design as ghd’s straighteners, has a similar mid-range price tag, and offers more temperature options.
