The 5 Best Rated Flat Irons

I would be lost without my flat iron. It’s by far my favorite go-to beauty tool. Flat irons aren’t just for straightening and taming frizzy hair, they’re also amazing for creating incredible curls and luscious waves. If you’re looking to replace your flat iron or want to try a different brand, check out my review of the 5 best rated flat irons.

The 5 Best Rated Flat Irons

Important Features To Look For In A Flat Iron

What features should you look for before purchasing a flat iron? Here’s a list of questions to consider before making your final decision:

1. How big are the plates? The plates are the part of the flat iron that heat up, and press against your hair. Plate widths range from 1.2 inch to 3 inches, with the average width being 1 inch. If your hair is long, I would consider going with a larger plate, and especially if you’ll be using the iron to curl your hair, as well as straighten it.

2. What are the plates made of? Most flat irons come with plates made of titanium, ceramic, or tourmaline. Each of these materials has its own unique advantages.

  •  Ceramic is an inorganic metal compound that emits negative ions, which is a good thing because hair carries a positive electrical charge. Keep in mind, some manufacturers simply coat their irons with ceramic to save money. While they might not cost as much, irons with plates that are simply coated with ceramic likely won’t work as well, and the coating will wear off over time.
  • Tourmaline is a crystalline gemstone that retains heat evenly, making it very effective for straightening, creating curls, and styling. Like ceramic, it also emits negative ions, and is generally a little safer for the hair then ceramic. Some plates are made with both ceramic and tourmaline.
  •  Titanium is a chemical element that is often used to coat the styling plates. Flat irons with titanium plates heat up extremely fast, and the heat is powerful. Titanium plates are great for people with naturally curly hair who want to create a sleek, tamed look, without spending a lot of time. However, the price tag is steeper for these types of irons.

3. How long is the cord? Flat irons with short cords are hard to maneuver. Make sure the flat iron you’re considering buying has a long enough cord to make it convenient to use.

4. Does it have an automatic shutoff feature? I don’t know about you, but there have been times I’ve left my straightener on, and had nightmares of my house burning down. Thank goodness for automatic shut-off, making this no longer an issue. And it goes without saying that the handle of your flat iron should always remain cool.

5. How much is the flat iron? Irons can range in price from $20.00 up to $150.00, and sometime even more.  Keep in mind, inexpensive flat irons may not work as well, and may even damage your hair. Pay attention to the size of the plates and what they’re made of, and make an educated decision from there. Take into consideration how often you use a flat iron, how thick your hair is, if it’s naturally straight or curly, and the condition it’s in.

Consider buying a higher-end iron if you use one every day, or if your hair is thick, damaged, or naturally curly. Also, look for irons that heat up to at least 420 degrees. Now that you know what to look for in a flat iron, let’s get to our fantastic contestants:
