Flat Iron Review GuideHair straightening has been around since the 1800s, and it surged in popularity during the 1960s, when stick-straight hair was all the rage with women. In order to achieve this look, many women used traditional clothes irons. However, these irons led to burned hair, burnt skin, and having to sit in uncomfortable positions. These days, the modern flat iron hair straightener heats up like a clothes iron, but it’s designed just for hair.

What Is A Flat Iron Hair Straightener?

A flat iron is very simple to use and only requires a bit of practice for desired results. A flat iron uses electricity to heat up the two plates. The plates can be closed together, and when placed over a section of hair, they glide smoothly over the top and bottom, perfectly straightening each section. A flat iron can be used on any hair type, and it can effectively straighten even the curliest hair. With a flick of the rest and a few interesting techniques, a flat iron can also be used to add curls or waves to hair.

What are the different types?

If you want to give yourself a new hairstyle at home without paying expensive salon prices, a straightener is just the tool you need to add to your bathroom. With so many different brands, sizes, styles, and colors, it’s easy for anyone to find their perfect hair straightener. However, the wide variety of choices also makes it quite difficult to narrow down the purchasing decision, especially if you don’t know much about styling tools. If you’re considering buying a flat iron, the first thing you need to know is the different types available to you.


Ceramic flat irons are the most common type of straighteners. The plates are made of ceramic, which heats evenly and helps prevent damage to your hair. These are typically the most inexpensive, although high-end models loaded with features may be just as expensive as other types of straighteners.


Instead of ceramic, the plates on these straighteners are made of titanium. Like ceramic, you’ll get even heating and less damage. The main advantage of titanium irons are that they are more lightweight than ceramic irons, so your arm won’t get tired when straightening very long or thick hair.


These are the most advanced straighteners and are also usually the most expensive. This element requires less direct heat to be applied to your hair, resulting in less damage. It also seals the cuticle, so your hair looks softer, shinier, and healthier after using it.

Rotating straighteners

Instead of two plates that click together, these straighteners have a brush clamp that works with a rotating barrel to straighten hair.

Travel flat irons

These mini flat irons are perfect for taking with you on vacation or even carrying with you for touch-ups on the go.

What are the advantages of owning a Flat Iron?

If you like to give yourself new looks for special occasions like prom, weddings, or date nights, a straightener is certainly something that you should own. A straightener allows you to transform curly, wavy, or frizzy hair into a smooth, sleek, and fashionable style. Straighteners are easy to use, and you can even use different tips and tricks to achieve a variety of styles. Flip your ends over, under, or make your hair pin straight. Try curls or waves that you can do at home in just minutes with a high-quality flat iron.

Considerations for Choosing the Right Flat Iron

If you’ve decided you want to give a hair straightener a try for the first time or you’re just replacing an outdated or broken tool, you need to arm yourself with knowledge before you begin shopping. After you’ve weighed out the benefits of each type of hair straightener, consider these key features before you commit to a purchase so you won’t end up with buyer’s remorse.

Temperature settings

Flat irons typically have adjustable heat settings. To avoid damage, you want to use the lowest heat setting possible. However, if you have very thick, coarse, or curly hair, you may find that you have to use very high heat to get your hair straight. Look for a flat iron that has many temperature settings and that are easy to change.

Plate size

There are several different plate sizes to choose from. A 1-inch plate works for most hair, but if you have very fine or short hair, you might want to choose smaller plates. If you have a lot of hair or it’s very long, you can straighten more quickly with larger plates.

Safety features

While performance is very important to ensure great results, it’s also important to keep safety in mind. Features like automatic shut-offs and tangle-free cords help prevent accidents and injuries.


Straighteners are available at a variety of price points, from less than $20 to several hundred dollars. Take note of what the plates are made of, different features, and overall design when considering price. Typically, more expensive straighteners are designed to last for years, are easier to use, and make hair look and feel better than ever.
