7 Best Curling Irons of 2023 [Tested and Reviewed]

The Bio Ionic Long Barrel Styler offers multi-level heat control. The clip has just the right amount of grip, resulting in beautiful curls on straight sections of hair. With just one wrap, the curls hold firm, producing ideal spiral curls. While the ends felt slightly dry, the overall texture was smooth and felt like it had retained moisture, and the damage was minimal, which is definitely a plus.

The quick heat-up time of 44.72 seconds allows for speedy styling even on busy mornings. With six temperature settings, it offers great usability through precise temperature control to fit different levels of hair damage and curling needs. This curling iron is a smart choice that allows you to create gorgeous curls in just one go, whether you prefer to leave your curls down or style them further afterwards.

The Whirl Trio comes with three different interchangeable wands, letting you customize the thickness of your curls according to your hair length and styling preference. When tested on straight hair, it produced beautiful curls overall, receiving high praise for its finish. However, as this is a wand curler that requires you to wrap the hair yourself, you may get a more straightened look if not enough tension is applied. Therefore, adjusting the tension while wrapping the hair will help you achieve your desired curls.

The fast heat-up time of 24.64 seconds is convenient, especially for quick styling before heading out. The elongated buttons are user-friendly, providing a wider surface area for easy operation. With five adjustable temperature settings, it offers the advantage of being able to customize the heat according to your hair's condition.

However, in our hair damage tests, although the hair felt adequately moisturized up to the mid-lengths, there was a noticeable dry and brittle texture towards the ends. With the inclusion of three different wands, this curling iron eliminates the need to purchase separate devices for different hair lengths, making it a recommended choice for those who prefer a versatile option.

The Neuro Unclipped Styling Rod features an extra-long barrel, making it convenient for styling long hair. Simply wrap the hair around the curling wand to create beautiful curls in one go that will remain intact even after running a comb through them. The longer barrel makes it easier to wrap hair, particularly if your hair has a lot of volume, and it ensures that heat is evenly distributed throughout, resulting in quick curl formation. It heats up in just 42.25 seconds, so you can save time as it warms up while you're brushing your hair.

The recessed buttons fit comfortably to your fingers, making them easy to press. The large LCD makes it easy to monitor the temperature, which is a nice feature. On the flip side, the efficient heat distribution across the hair during curling can lead to dryness and increased frizz, making it difficult to protect the hair from damage. Although the test for gentleness yielded mixed results, this styling rod remains a user-friendly option for individuals with long or thick hair.

The B1 Rotating Curling Iron automatically spins the barrel to create curled hairstyles. When actually wrapping sections of hair around it, it produced distinct curls, earning high praise in terms of overall finish. It creates well-defined curls with a natural spiral shape, making it suitable for creating hairstyles for outings or parties. Once they get used to operating the button for the direction of rotation, even beginners can easily create curled hairstyles.

The large buttons are easy to press. Its 50.36-second heat-up time is acceptable even on busy mornings. On the downside, while the wrapped hair strands maintained a soft and springy texture, the hair ends tended to become dry and slightly coarse. This one is perfect for beginners or those who have been hesitant to use curling irons due to their lack of technique. Since it creates curls simply by clamping the hair ends and pressing a button, it’s highly recommended for anyone looking for an easy-to-use curling iron.

The SinglePass Curl is designed to create glossy curls with ease in just one try. In our curling tests, it was able to create tight and precise curls. The length of the clip allows you to wrap a larger section of hair at once. Moreover, the barrel has excellent glide, making it less likely for hair to tangle, even for individuals with long hair or concerns about hair damage.

Instead of separate power and temperature adjustment buttons, the device features a rotating mechanism at the base for temperature control. It offers five temperature settings, allowing you to adjust according to your hair's condition, which is definitely a plus. On the downside, the hair lost its moisture and felt dry after curling, resulting in a slightly coarse texture. In addition, it took 87.11 seconds to heat up, which might seem somewhat long when you're in a hurry.

The Conair Double Ceramic is designed to create beautiful classic curls. After curling, the hair maintained its overall moisture, and didn’t feel dry to the touch. It received high ratings in terms of preventing damage to the hair, as testers hardly noticed any. The recessed buttons fit the fingers nicely and are easy to press.

It offers 30 temperature settings, allowing precise adjustments according to the condition of your hair, which is a major plus. However, due to the weak grip of the clip, the curls didn't turn out as defined as expected, resulting in a flatter look. For this reason, the product received less than favorable ratings for finish. In addition, it takes 65.99 seconds to heat up, which might feel a tad too long when you're in a hurry.

The Remington Pro Multi-styler features twisted plates designed to offer both straightening and curling capabilities in one. One of the highlights of this product is its quick heat-up time. It reaches the desired temperature in just 32.6 seconds, making it especially convenient for busy mornings when time is limited. When actually curling the hair, the ends may feel dry, but the midsections have a pleasantly moist texture. However, since the curls are formed by sliding the plates, it's difficult to avoid some friction and potential damage to the hair, which is a drawback.

The Multi-Styler received high praise for its user-friendliness, thanks to the large display that makes it easy to monitor the temperature and its five adjustable heat settings. On the downside, the curls created by this styler are quite tight and can appear overly defined, giving a somewhat unnatural look for everyday use. However, if you're looking to achieve voluminous and glamorous curls for special occasions or parties, it can be a good choice.
