What other experts liked

Anti-static technology reduces frizz and ensures even performance. Heats up in a matter of seconds.
- BestReviews
Not only does it heat up quickly, but this ceramic iron comes with an auto shut-off that will turn it off after 60 minutes.
- Bustle
It has a durable and anti-static design with longer plates (ceramic) and an auto shut-off technology.
- The Beast Reviews
The device can reach 410 ͦF high, making it suitable for both home and commercial use.
- HQ Review
This affordable straightening iron is ideal for travel or for those who need a basic straightener.
- The Consumer Guide
The flat iron’s light weight was a plus.
- Your Best Digs
The maximum heat of 410°F makes it a good hair straightener for thick, coarse hair.
- My Straightener
Floating ceramic plates are coated with titanium for even heating and a silky smooth glide through the hair, and the temperature is adjustable up to 410º, so you can tweak it according to your hair type.
- Good Housekeeping
With titanium coating on the plates, the flat iron heats up in 30 seconds but won’t leave a ton of damage in its wake
- InStyle
I also liked the fact that the plate has rounded edges, allowing you to have loose curls at the bottom of your hair for that bouncy look.
- Low Tech Times
The 360° swivel cord provides the user with freedom of movement and super easy maneuverability
- InStraight
The temperature of this iron can go up to 410 degrees which is exactly how the salon professional irons perform. You don’t even have to wait that long because the heat goes to maximum in just 30 second, therefore saving up a lot of your time.
- Flat Iron

What other experts didn't like

The casing felt cheap (probably because the straightener is cheap), and it was hard to really clamp the plates together.
- New York Times Wirecutter
A few units initially emitted a plastic smell, which ultimately cleared after subsequent uses.
- BestReviews
It doesn’t reach temperatures as high as other devices and has smaller plates may not be ideal for thick or curly hair.
- The Consumer Guide
It lost points with our testers because of the ‘burning plastic’ smell it emits while heating up.
- Your Best Digs
The buttons are on the side, so you might push them by accident.
- My Straightener
The lowest temp it can achieve is no less than 310 degrees, not suitable for sensitive hair type.
- Low Tech Times
Sometime emits smell like electric burning
- Flat Iron

Our Hair Straightener Buying Guide

Do you rely on the best tools to get your hair just perfect every day? If so, you’ll want the best hair straightener you can get. This tool can take frizzy hair down to a stunning straight style with no time at all. With several varieties available, you will need a bit of information to find the best straightener for your needs. Let’s see what the best straighteners have to offer.

A hair straightener, or flat iron, is a product that looks like a hefty set of tongs. You “brush” your hair between the two flat handles that are preheated. Your hair then turns out silky smooth with little to no frizz. Although it seems like a simple product, flat irons have gone through many transformations to keep your hair damage-free. Straighteners are made from many different materials, each claiming to be better than the other. Some materials used in hair straighteners include titanium, silicone, ceramic, Tourmaline and Teflon. They will all effectively straighten hair, but some are better for certain hair types than others.

Simplemost Media

You will have to know your hair type to decide on the best hair straightener for you. If you have fine hair, you’ll want to choose a straightener with multiple heat settings. Fine hair can be singed by hair straighteners so it is important to use low heat. The Remington Anti-Static Flat Iron Hair Straightener has digital inputs for you to set the temperature you need. If you have thick hair, you’ll need a high-heat straightener and temperature control isn’t as important. If you have curly hair, you’ll want a flat iron that features Tourmaline as it prevents the frizz that curly hair is known for. There is a straightener for every type of hair to prevent damage and give you that perfect straight, frizz-free hair.

If you are a frequent flyer, invest in a flat iron that travels well. The HSI Professional Ionic Flat Iron Hair Straightener has its own travel bag, a heat-resistant glove, and a travel pack of argan oil. Find convenience when you are on the go with this great travel flat iron.

DWYM Fun Fact

Tourmaline is a gemstone that is crushed into extremely small particles and then infused onto the hot plates of the iron. This substance allows the flat iron to straighten hair at a much lower temperature. These flat irons are becoming quite popular especially for consumers with fine hair.

The Hair Straightener Tips and Advice

  • Although it isn’t necessary, using a heat-resistant glove to handle the flat iron will make you much more comfortable while straightening your hair.
  • Choose a flat iron that has anti-static characteristics to make straightening easier.
  • Try to use a protective product like argan oil to give your hair a sheen and also protect it from high heat.
  • Opt for a hair straightener that’s sturdy and durable; you’re looking for a hair straightener you can keep for as long as possible.
