We Review 5 of the Best Hair Straighteners

We’ve picked 5 of what we consider to be the best hair straighteners for review in 2022. We collected them based on their ability to smooth and straighten all hair types from fine or treated hair to coarse and curly hair with one or two passes. Nobody wants to spend hours sectioning and running the flat iron over the same piece of hair 3 or 4 times. It could literally take hours to do that. The straightener also needs to lock down the silky, soft texture between washings without having to make extra passes every day to areas that have frizzed or curled.

BIO Ionic Onepass Straightening Iron

The BIO Ionic Onepass Straightener has satisfied customers who say they would recommend this to their friends and family. In fact, many of BIO’s first buyers were beauty consultants and hair stylists who would sell these devices to satisfied salon customers. This might be because it was originally created by an experienced, famous hair stylist who knew the value in a great styling device.

The silicon speed strips make this truly a one-pass straightener. Even coarse and curly hair only needs one pass of this flat iron to be smooth and sleek.

Instant heat can be a problem if you’re not expecting it to heat quickly. Always leave the device unplugged after use.

Common Questions:

Are the white and black versions the same?

Yes. They are.

Can the BIO be used while traveling?

The BIO doesn’t have dual voltage, so you’ll need a converter.

Is there a digital readout on the device?

There is no digital readout on this straightener. There’s a simple turn button that allows you to change the temperature.

The BIO Ionic flat iron heats incredibly fast, and with the silicon speed strips, it’ll give you the shiniest, straightest hair you’ve ever seen in your life. It’s a fast styling tool that won’t require you to spend hours in front of the mirror each morning.

  • Lightweight and slim


The slim, lightweight design means it’s easy to straighten hair and continue with other styling options. There won’t be any hand or arm fatigue while styling.


Some users of the BaByliss Pro mention that the top of the iron gets incredibly hot. At 450 degrees, it’s never good to try to touch any part of the iron.

Common Questions:

Does the BaByliss Pro has an auto shut-off?

It doesn’t. You’ll need to be extra careful to shut this device down after use.

How many heat settings are available on this straightening iron?

The turn dial has 50 stops that allow a wide range of heat settings.

Why are the plates mirrored?

This is because the plates are made of titanium, and not another material.

The BaByliss Pro heats up incredibly fast, which cuts down on styling time. It’s meant to work on curly, frizzy, or coarse hair. Hair that is notoriously hard to straighten will benefit from this flat iron.

LumaBella Keratin Dual Touch Hair Straightener

With the Keratin-infused plates, the dual touch flat iron is an incredible styling tool in your beauty arsenal. You won’t get an oily residue on your hair with this straightener, either.

  • 4-year warranty
  • Floating plates
  • Smart heat sensor
  • Turbo heat boost


There are 5 heat settings with the LumaBella. Each is made to specifically work on certain hair types. They range from 300 to 450 degrees.

The plates have been infused with keratin meant to condition as the heat works on straightening the hair.

Reduces temperature when it detects dry sections of your hair.


The only complaint with this iron is that it has no hook to hang it or mat to lay it down on between uses. You’ll have to buy your own mat to protect the furniture. It’s definitely needed since this flat iron reaches 450 degrees.

Common Questions:

Does the device have an auto shut-off?

The device will shut itself down after 1 hour.

Can this device be used for curls?

All straighteners can be used for curling if they are slim enough. This device is slim and ergonomic.

Does the straightener work on weaves?

Weaves made from human hair can be styled the same as your natural hair. It’s best to keep extreme heat away from other types of weaves and synthetic materials.

With a smart heat sensor for damage control as well as micro conditioners in the plate itself, this is a styler that will make your hair healthier and smoother after use even when it’s applying high heat to the hair.

T3 Single Pass X Flat Iron

The manufacturer calls this hair straightener the “hair whisperer”, and we might have to agree with that. The straightener soothes and smooths the hair, so it stops being a scary, curly mess, and behaves as you want your hair to act on a daily basis. This means that the hair won’t frizz up later in the day, either. While nothing can save your hair if it becomes damp and rains, for normal days, you won’t have to worry about reapplying the iron to your hair.

Accessories help you with your styling process. There are clips for sectioning hair as well as a heat mat for resting the device.


The audio might be a bit annoying, but that can be easily fixed by holding down the power button to shut off the sounds.

Common Questions:

What material makes up the plates, and what size are they?

The plates are ceramic and tourmaline. They are 1.5 inches wide.

Can this be used on treated hair without damaging it?

With the T3’s heat range, you can start at 260 degrees, which is a good temperature for brittle, treated hair.

Can the T3 be used for hair flips and curls?

It’s easy to angle the straightener at the ends of the hair to give you little flips and curls throughout.

The T3 has tourmaline and ceramic plates that keep your hair from being pulled and yanked through the device during straightening. This can happen frequently with cheap flat irons.
