Curling irons, also known as curling tongs, create waves or curls in hair using a variety of different methods. There are many different types of modern curling irons, which can vary by diameter, material, and shape of barrel and the type of handle. The barrel's diameter can be anywhere from .5 in (1.3 cm) to 2 in (5.1 cm). Smaller barrels typically create spiral curls or ringlets, and larger barrels are used to give shape and volume to a hairstyle.

Both inexpensive and high-end flat irons come with a wide range of features. If you plan to travel out of the country often, then a tool with dual voltage might be a good option. Or you might find that the Bio Ionic’s vibrating plates are something you can’t live without after trying. A long cord that swivels at the end of the handle to ensure ease of use might also be an important feature for you. Some features you might not need include pads to rest your flat iron or gloves to protect your hands — both accessories our testers didn’t think were necessary. When researching flat irons, make a list of your must-haves and make sure the one you choose includes your top features before purchasing.
4. The button placement is very similar to the Remington flat iron. When the iron is powered on, quickly press the power button 2 times and a small lock icon will appear on the digital indicator under the Fahrenheit symbol. When the lock icon is visible you cannot change the temp or turn it off by accidentally pressing the buttons. To unlock, quickly press the power button 2 times again and the lock icon will disappear.
Before explaining the advantages, let’s discuss the heating process. Flat Iron does the basic purpose of heating so that the hair follicles can flatten. Flattening of follicles is needed to create any hairstyle. Hair follicles contain natural moisture. When we heat the hair, the natural moisture gets eliminated. That’s why hair ends up with the rough texture.
Cleaning your flat iron is critical to ensuring it works as well as it did the first time you used it. Over time, hair product can build up on the plates. This buildup can lead to inconsistent styling results and major snagging. To clean your flat iron, simply wait for it to cool down and wipe the plates with a cotton swab or soft cloth coated in rubbing alcohol.

The plates in this techy tool house an internal microchip that constantly measures and maintains an even temperature. With no random hot or cold spots, you'll get smoother, straighter, strands in fewer passes. (Spoiler alert: Fewer passes equal less damage). Adjustable temperature settings — from 260 to 410 degrees — make this ideal for any and every hair texture.
