The automatic sleep mode is also great, as it turns the iron off if left unattended for 30 minutes. This styler is hot in just 30 seconds, ideal if you’re in a hurry first thing or you need to get ready for a party quickly. We love the smooth, floating ceramic plates that are suitable for all hair types and lengths. This makes an easy job of straightening slightly knotted hair, too. While some may be put off by the fact you can't change the temperature to suit your individual needs, 365ºF is considered a perfect temperature because it styles effectively without damaging hair.

GHD have pulled it out of the bag yet again with their Max Styler. This the best flat iron for curling – yes, such a thing exists. We're well aware that buying a flat iron for curling hair seems pointless, but for those who want the best of both worlds in one appliance, this is the buy for you. No matter if you have short fine hair, a frizzy medium-length head, or long thick locks, this styler can tackle your mane with ease. Since the plates on the GHD Max Styler are noticeably wider than other models, this makes curling hair an easier and very much quicker job. To be exact, this model features broad, two inch (50.8mm) plates. The plates on the GHD Max Styler are contoured to create bouncy curls in one swift motion – or big waves if that's more your style. This also makes the process of curling hair with a flat iron a lot smoother.

The DAFNI Allure Cordless Straightening Brush is a great buy if you're a frequent traveler, if you have hair that never stays straight, or if you have fine hair that's easy to manage. This flat iron brush works like a brush, meaning it's very easy to use no matter how good or bad you consider yourself at doing hair. And to make things better, due to its nature, it detangles your hair while straightening it. Bearing in mind that it works on a battery, it heats up in two minutes and can last for as long as three hairstyles or 30 minutes to be exact. When we tried, it lasted for around two heads on long, thick hair. It also works great on hair extensions. When the battery is low you just need to give it a charge – it's compatible with USB chargers – and wait for just two hours. With an auto shut off mode so that after 15 minutes of inactivity it turns off, this straightening brush will do less damage to your already fine hair while in use. This is due to the fact it doesn't feature plates like usual flat irons, and the temperature never goes over 365°F to protect your follicle. We love to hear it. It also works wonders on frizzy hair – tried and tested – so don't worry if your hair is untameable. Simply pop this hair straightening brush in your handbag, hand luggage or suitcase for straight hair wherever you are, whatever you're doing. It comes with a pouch and a case to protect its bristles.

This high-end flat iron gets rave reviews from true beauty aficionados, but the high price isn't for every budget. The exclusive design of the Dyson Corrale Straightener centers around its notched plates made from manganese copper alloy, designed to shape around your hair. It gathers hair for more control, which produces the same style results with less heat and breakage than solid plates. Intelligent heat technology regulates the temperature of the plates up to 100 times a minute so when you choose one of the three settings (330°F, 365°F and 410°F) the temperature stays put. The Dyson Corrale comes with a cord, but if you prefer the ease of cordless, it does that too. Charge the styler on the included charging dock for 70 minutes and get up to 30 minutes of cord-free styling. The flat iron shuts off automatically after just 10 minutes and features an OLED screen that shows the battery level, temperature, and charging status while in use.

How to buy the best flat iron?

Shape
The main thing when choosing a flat iron is that you want to avoid damaging your hair with cheap designs or those that overheat your hair. The best models will last for years to come, so it’s worth investing in a pricier model as you do get what you pay for. All flat iron plates are flat but it’s the edges you need to check. If the plates and outer edges of the plates are slightly rounded, it will be easier to turn your flat iron into a curling iron. A flat iron with sharp edges, on the other hand, will be less adaptable but may produce slightly straighter hair.

Plate material and width
These are usually made from ceramic or in some cases, titanium. Titanium heats up quickly, applying higher temperatures more evenly and tend to cost more than ceramic versions. They are recommended for really curly or coarse hair. Ceramic is great value and really effective with even heat that suits most hair types. The wider the plates, the quicker you’ll achieve the result you want.

Variable temperature
High heat certainly means faster straightening but it’s not ideal for all hair types, so look for a model with variable settings that will reduce damage over time.
