Best cordless straighteners 2023: Effortless, healthy hairstyling on the go

Want smooth, straight hair when you’re away from home? These are our favourite cordless straighteners for your suitcase or handbag

If you love to keep your locks sleek and frizz-free when you’re travelling, or want to change your look after work or the gym, then cordless straighteners can be invaluable.

Made to be used wherever there’s no plug socket readily to hand – from backstage at fashion shows to the middle of a campsite – cordless straighteners are portable, rechargeable tools that are perfect for people who are constantly on the move.

That’s not to say cordless straighteners don’t have a place in the home, too. Moving the straightener around the back of the head is easier without a cord to get in the way, and a cordless straightener can be used wherever your mirror is – whether that’s near a power socket or not. Cordless straighteners typically provide around 30 minutes of use on a full charge, which is enough to get ready in the morning, fix up your look for an evening event, or tidy up after a workout.

Losing the cord doesn’t mean sacrificing quality, either – the latest cordless hair straighteners share the technology used by their corded cousins, from adjustable heat settings and ceramic plates for a glossy finish, to ionic technology that speeds up styling and reduces damage to hair.
To help you choose the right cordless straightener, here’s our guide to the best cordless straighteners for frizz-free, sleek and shiny locks.

Best cordless straighteners: At a glance

How to choose the best cordless straighteners for you

How do cordless hair straighteners work?

Like other cordless devices, straighteners use a rechargeable battery (usually a lithium-hydride or lithium-ion battery) housed inside the device, which needs to be charged before use. Cordless straighteners can be charged either directly from the wall or via a charging dock; some straighteners can even be charged using a USB cable running from a laptop or phone charger. Cordless straighteners often feature a travel-safe mode that disconnects the battery, allowing them to be carried on flights without risk of accidental activation and fire.

Charging usually takes between 1-3 hours, and a full charge will last around 30 minutes, depending on usage. We’ve noted both times in our individual reviews below.

How should I use my cordless hair straighteners?

As with corded straighteners, always ensure hair is completely dry before straightening (rough-dry the hair first with a hairdryer if you’re straightening after a workout). Section the hair prior to styling and spray with a heat-protective product to keep heat damage to a minimum and help your chosen style to last longer.

Start on the bottom layers of hair near the neck, working your way up to the crown in small sections (an inch wide is a good size to aim for). With practice, you should get your straightening routine down to less than 30 minutes, or one single charge of a cordless tool.

What other features should I look for?

Many cordless straighteners have styling plates coated in ceramic, which heats more gently and evenly, producing a soft, shiny and glossy finish. Plates might also be coated in titanium, which heats up very quickly. As well as reducing the overall time required for styling, this reduces the amount of time that the hair is exposed to heat.

Some cordless straighteners come with adjustable heat settings. If you have healthy, medium-textured hair, the optimal temperature for heat treatments is 185ºC. Fine, damaged or treated hair will prefer a lower heat setting of around 165ºC.; higher temperatures of around 200- 210ºC are designed for thick, coarse hair or tight curls.

Look for straighteners with curved edges if you want to create curls, waves and flicks shaped around the body of the irons. Cordless straighteners usually switch off automatically after a period of inactivity to preserve battery life – we’ve noted the switch-off time below.

How we test cordless hair straighteners

At Expert Reviews, we know that hands-on testing is what gives us the best and most complete understanding of a product. So we test all of the hair straighteners we review, either at home or during a live product demonstration. We use the tools on clean, dry hair, using the different temperature settings where applicable. Whenever possible, we also test on more than one hair type or texture.

During testing, we confirm the weight and dimensions of the cordless straightener and the material used in the hot plate. We then record the time it takes for the tool to heat up after being switched on, and how long it takes to style a full head of hair, noting the hair texture that we are testing it on. We also confirm how long the battery lasts from a full charge and we note the time it takes to fully recharge.

We evaluate the overall ease of use of the cordless straightener, how it feels in the hand and the finish and feel of the hair after straightening. Finally, we note how well the straightened hair lasts over a typical day of wear.

The Revamp Progloss Liberate Cordless Ceramic Compact Hair Straightener is a diminutive device which uses ceramic floating plates to glide easily through the hair without pulling or tugging.

2. Dyson Corrale: The best premium cordless hair straighteners

Price: £400 | Buy now from Boots

Dyson’s award-winning cordless straightener uses flexing manganese-copper alloy plates to smoothly grip and gather hair, straightening quickly and easily with just one stroke. Thanks to an intelligent heat control system that monitors the temperature of the plates to ensure even heat distribution, the Dyson Corrale creates beautifully sleek and frizz-free hair with minimal damage.

The Corrale has three heat options: 165ºC, 185ºC and 210ºC, so you can choose the temperature that best suits your hair texture and desired style. The flexing design means that the plates mould themselves gently around the hair, so excellent straightening results can be achieved without needing the very highest temperatures and at speed.

The four-cell lithium-ion battery charges in just over an hour, and lasts 30 minutes once fully charged; the Corrale’s one-stroke styling means a single charge is enough to fully style most heads of hair.

Designed for styling on the go, the Unplugged is very light at just 300g – half the weight of comparable straighteners. At 22cm long, it’s also compact enough to fit in a handbag for day-to-evening styling.

The straighteners are small but they still feature GHD’s familiar ceramic plates and dual-zone heat sensors to maintain a safe, consistent temperature of 185°C across the plates. The tool heats up in only 45 seconds, and a single battery lasts 20 minutes from full charge, which takes 2 hours.

The Unplugged is charged via a standard USB-C port, so you can charge from any USB cable – from a wall plug adapter, or even from your laptop if you’re fixing your hair at work. The tool switches itself off after three minutes if not used, to help preserve the battery.

The styling plates are 2cm across – slightly narrower than the plates of full-size stylers, but the handle is a similar width to that of GHD’s other stylers and feels comfortable and nicely balanced in the hand.

The GHD Unplugged comes in a choice of stylish matte black or white, and is great for hair touch-ups during the day.
