The Best Flat Irons

Today’s flat irons are different than the ones that existed 10 years ago. Back then when you bought a flat iron you expected it to take your already dry hair to the next level of straightness. These days, flat irons can do so much more. You can eliminate frizz with the help of infrared sensors or even use your straightener to create beachy waves. All of these advancements in technology are great for your hair, but they give you a lot more to consider before deciding which one is the best for you.

We reviewed dozens of flat irons of all shapes and styles to bring you the perfect options for whatever you are looking for, be it tamping out frizz or taming your wild curls into a pin straight tresses. Before deciding which straighteners were the best of the best, we considered things like the differences between ceramic and tourmaline plates, applied technologies (seriously, there is a flat iron that uses infrared on this list!) and even whether or not they could be used on damp hair. In the end we chose 25 of the best flat irons that can give you that salon fresh style from the comfort of your own home.

Who Should Buy a Flat Iron

If you have silky smooth, board straight hair already, you are in the wrong place. However if your hair is curly, kinky, or prone to frizz you may benefit from using a styling tool like a flat iron. While many other styling tools, like curling irons and hot rollers, can take your hair from straight to curly, only a flat iron can do the opposite.

Keep in mind that flat irons only offer a temporary change, and your hair will generally return to its natural state after the first wash. If you are seeking a permanent change to straight hair, consult a local salon professional about the services they offer. Until then, you can take the look for a test drive by using a flat iron in the comfort of you own home.

Important Features to Consider

A flat iron should have a few important features. Here’s what to consider when selecting a flat iron:

  • Adjustable heat settings. Everybody’s hair is different and will require a different heat setting in order to achieve silky smooth pin straight hair. Adjustable heat settings allow you to choose which temperature works best for your hair. For example, if your hair only has a slight wave, you will want a lower heat setting. However, if you have a tightly wound curly, your hair will require a little more heat to get it to relax enough to lie flat.
  • Barrel size. The size of the barrel will impact how long it takes you to straighten your hair in many cases. A smaller barrel (anything under an inch) will require far more passes than a larger barrel (anything over an inch). Smaller sized barrels are perfect for short hair, or hair that will straighten without too many passes. However if you have a thick head of hair that requires more than one pass on each section, a larger barrel will cut down on how much time it takes you to complete  your desired look.
  • Wet and dry settings. Not all flat irons are created equal. Some require that your hair already be completely dried before you begin while others will work just fine on damp or wet hair. Before purchasing a flat iron, consider whether or not you prefer working with already dried hair, or like to do it all at once with towel damp hair.

Frequently Asked Questions

What is a flat iron and how does it work?

A flat iron is a hair styling product that uses heat to straighten hair. The device has two plates at the end of a set of ton shaped arms. Once it has heated it to the desired temperature, you take a small section of hair and beginning at the top of your scalp, squeeze the plates together and run them down the length of your hair. Flat irons can straighten a variety of hair types. The type of flat iron you choose will depend on the type of curl type you have, and whether or not you want a flat iron that does anything other than straighten. For example, some flat irons can actually be used to give your hair curls as well.

On the flip side, there are no curling irons that can be used to straighten your hair. Making flat irons a two-in-one styling product (check out our top five list to see which of our recommendations pull double duty).

Of course, it never hurts to buy the two separate products. You will always achieve more optimal effects by using a tool that is specifically created for the look you are trying to create. You can check out our list of the best curling irons to get a good idea of what we consider the best the market has to offer.

What do you put on your hair before you flat iron it?

Before you put anything into your hair, you will want to make sure that it is designed to be used with heating elements (like flat irons, blow driers and curling irons). There are a variety of products you can use: solutions that protect against heat damage, products that are designed to add extra shine when activated by heat and oils that help trap your hair’s natural minerals to keep it shiny and healthy.

Keep in mind that some products can only be applied to wet hair, which means if you have a flat iron that can only be used on dry hair, you’ll need to apply it before you begin blow drying.

Can you use a flat iron on straight hair?

Absolutely! Many people with straight hair use flat irons to help with frizz and smooth down fly-aways. If you already have fairly straight hair you can get away with using a flat iron with a smaller barrel and a lower heat setting (which will save you time and money). Of course a larger flat iron with a range of heat settings will work as well and may help you get an even smoother and more uniform look.

Just beware that you aren’t using too much heat. Excessive heat use can damage otherwise healthy hair, and no amount of flat ironing can hide badly damaged hair.

How do you keep your hair straight after using a flat iron?

After you have done all the work of straightening your hair, you’ll want to make sure you’re doing the right things to keep it looking its best. Use styling products designed for straight hair (things like mouse or gel are too heavy and too wet to achieve a straight glossy look). Also, you’ll want to avoid getting it wet. If it’s raining, consider wearing a hat, carrying an umbrella or donning a wrap. You can also get a little more wear out of your look by skipping a few shampoos. Instead, use a dry shampoo (which will soak up any excess oil produced by your scalp) and get a few more days out of your look.

As an added bonus, the less you use heat elements on your hair, the better your hair will look. So if you can manage to make a straightening session last a few days, your hair will thank you for it!
