The DAFNI Allure Cordless Straightening Brush is a great buy if you're a frequent traveler, or if you have hair that never stays straight. We know the struggle. Simply pop this hair straightening brush in your handbag, hand luggage or suitcase for straight hair wherever you are, whatever you're doing.

Easy to use
This hair straightener 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.

It's super compact and since it comes with a pouch, it's easy to pop in a bag or your luggage. We think it's a great device to take on city breaks, staycations or to your friend's house. It's also a great buy if your plug socket is miles away from your mirror (this is often the case with hotel rooms, too).

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 hair while in use. This is due to the fact it doesn't feature plates like usual hair straighteners 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. As for quick touch-ups, this hair straightener should be your go to.

GHD have pulled it out of the bag yet again with their Max Styler. We think this the best hair straightener for curling. We're well aware that buying a pair of straighteners for curling hair seems pointless, but for those who want the best of both worlds in one appliance, this is the buy for you. What else do we love?

Suitable for all hair types
No matter if you have short fine hair, a frizzy medium-length barnet or long thick locks, this hair straightener can tackle your mane with ease. 

Wide plates
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.

Contoured edges
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 straightener a lot smoother.

See our buyer's guide to the best curling wands if it's really curly locks you want.

How to buy the best hair straightener

The right shape
The main thing when choosing hair straighteners 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 straightener 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 straightener 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.
