1. Best Overall: BaBylissPRO Nano Titanium Flat Iron


Coming in at number one on our list of the best professional flat irons and only this iron on our list that is intended to be used on damp hair, BaByliss promises “ultra-shiny, pin-straight styles with just one pass”. Not having to fully dry your hair before straightening it can be a big time saver. When you are using a regular straightening iron on wet hair, the steam damages cuticles.

The hair may be straight, but it can be dull and look damaged. Vents are built into the plates and the housing so the steam can escape. Hair is noticeably shinier and more natural feeling than when you use a regular straightening iron on damp hair.

BaByliss Pro uses its trademarked Nano Titanium technology to fully harness the heat-conductive powers of titanium. Their irons straighten hair faster and provide long-lasting results. The titanium plates are smooth, corrosion-resistant, and conduct ultra-high heat. While the plates are a standard 1.5″ wide, they are 5″ long for faster straightening.

The longer plate means larger sections of hair can be styled at a time. Vents are built into the plates and the housing so you can iron damp hair without the damage steam usually causes. The Ryton housing keeps the handle cool for maximum comfort as you style. It weighs under a pound and has a slim, hand-fitting handle design. It boasts temperatures up to 450° using integrated ceramic heaters.

The adjustable heat setting provides a 50 heat setting that makes you more comfortable when using it. Different hair types need to set different heat settings to show better results. Please take some care when using the highest level of heat setting. For more information about the product, watch this video.


  • Styling damp hair saves time.
  • Vents in the plates and handle prevent the damaged steam usually caused to your hair.
  • While the size is a standard 1.5″ wide, they are 5″ long meaning you can style a larger portion of hair at a time.
  • The lightweight, slim design and Ryton housing make styling easy, cool, and comfortable.
  • It works either dry or wet hair, so you get the best of both worlds.


  • The temperature setting dial can easily be moved without the user realizing it, resulting in too little or too much heat.

2. Best Premium: GHD Gold Professional 1″ Styler


Going for the gold is all about the next generation of the styler. The GHD Gold Profession 1″ Styler features advanced heat technology to curl, wave, or straighten your hair. The gold plates have ceramic heaters to provide even heat across the surface. The contoured plate edges and round barrel make curls and waves easy. The GHD Gold Professional 1″ plates deliver smooth, frizz-free hair with a healthy shine.

It reduces snags and snarls, making the pass quick and easy. The styler heats up quickly and the plate guard allows you to pack up the styler as soon as you are done; no waiting! While the temperature is always 365°, it works just as well or better than other irons at higher settings. For a complete overview of the product, you can also check out this YouTube video.


  • The heat setting of 365° is enough to style most hair without worrying about burns or heat damage.

3. Best Value For Money: HSI Professional Digital Ceramic Flat Iron


At number three on our list of the best professional flat irons is the HSI Professional Digital Ceramic Tourmaline Ionic Flat Iron Hair Straightener. Salon quality tools and great customer service is how HSI Professional has built its worldwide reputation. Some flat irons boast ceramic and tourmaline plates but are just metal plates with ceramic and tourmaline coating.

These are 100% True Solid ceramic and tourmaline plates that use advanced infrared heat. Infrared heat works from inside the hair cuticle, sealing in moisture for healthy, shiny-looking hair. Heat-balanced microprocessors are located across the plates, constantly monitoring and adjusting the temperature. Whether quickly styling your hair for the day or taking extra time to prepare for a big night out, you still want your tools to be easy to use. The LCD screen allows you to ensure you get the exact temperature you desire.

The 360-degree swivel cord keeps things moving along without annoying cord knots. Straight hair, curled locks, and even flips are easy thanks to the curved edges. The HSI Professional Digital Ceramic Tourmaline Ionic Flat Iron Hair Straightener allows you to achieve a salon-look style at home. The adjustable temperature setting starts from 240°F and goes up to 450°F which makes the flat iron very easy for all types of hair. The flat iron heats quickly, and easy to change the temperature is enough to do the job quickly.


  • With an adjustable temperature range from 240° to 450° Fahrenheit, there is a setting for all textures.
  • LCD display allows for precise temperature control so you can learn the least amount of heat necessary to achieve your salon style.
  • 100% Ceramic plates with tourmaline coating, which means the plate will not flake like some cheaper flat irons.
  • Smooth floating plates reduce snags and pull as you style.
  • Negative ion technology heats hair from the inside, sealing in moisture and smoothing the cuticle surface.
  • Microprocessors located along the plates maintain even heating eliminating flat iron hot spots.


  • The flat iron plates are only 1″ wide.
  • Thicker and/or longer hair may take longer to style.

Our Editors Say
“When it comes to hair straighteners, I’ve tried a lot of different brands and models over the years. So when I was given a chance to try the new HSI Professional Flat Iron, I was excited to see how it would perform. Overall, I was impressed with the HSI.” Edna Martin, HSL Editor

4. Best For Fine Hair: Solano Sleekheat450 Flat Iron


Comfort and function meet on this Solano Sleekheat450, making your morning hairstyling routine one that looks like you came out of a salon. ​The professional ceramic and tourmaline plates are beveled on all sides. This allows your hair to glide through the plates and offers the versatility of making curls and flips. Far infrared heat dries the hair from inside the cuticle improving strand health.

Negative ions reduce frizz by locking in moisture for fewer flyaways. Cool touch tips keep your hands safe and comfortable. The flat iron heats in about a minute but has instant heat recovery. Each pass has a consistent, even heat delivered to the section of hair for more control and a quicker styling time.

The variable temperature control allows you to pick just the right temperature for your hair type. With a range of 170°F to 450°F, everyone from fine, thin hair to thick, coarse locks can use it. The 1 1/4 inch size is slightly larger than the standard 1 inch of other models, which means fewer passes and less time.


  • Ceramic plates keep the heat evenly distributed across the surface meaningless hot spots and damage to your hair.
  • The added tourmaline and beveled plate sides give you a smooth glide and easy curls and flips without an additional tool.
  • With a temperature range from 170°F to 450°F, you can find the right temperature for your hair no matter the type or texture.
  • Negative ions and far-infrared heat seal in moisture and minimize static electricity for a healthy-looking shine.


  • Defined as “Instant Heat” by Solana, the straightening iron takes a full minute to reach the desired temperature. Users who have only a moment for a touch-up or a time-crunched morning may find this a little too long when compared to other irons.
  • With the plates measuring 1 1/4 inches, it is larger than many straightening irons. However, those with thick, long, or coarse hair may still need a larger surface to speed styling times.

5. Best For Frizzy Hair: BIO IONIC Onepass Straightening Iron


BIO IONIC claims their Onepass Straightening Iron is the fastest ever. What makes this iron so different is the silicone speed strips on the edges of the plate. These strips keep your hair in place during the pass to prevent it from bunching up or slipping out of the iron too soon. The plates are made from nano ionic minerals for high levels of negative ions and infrared energy.

Breaking down larger water molecules into smaller ones allows for greater absorption into the cuticle. This means it hydrates the hair from the inside to create smooth, healthy-looking hair.

The 1-inch plates are perfect for adding curls or flips to your hairstyle, eliminating the need for a separate curling iron. Other irons can take a moment to recover lost heat, but the BioCeramic heaters in this iron recover it quickly. Consistent heat makes for a consistent experience lock after lock.

The 9-foot swivel cord gives you the freedom to move around in front of the mirror with less cord snags and knots. The Bio Ionic OnePass Flat Iron has an ergonomic handle, that fits easily and comfortably into your hand for more stability and control.

The adjustable heat settings range from 240° to 400° so you use just the amount of heat you need to get the job done without damaging your hair. Multi-level heat control manages your hair correctly. The flat iron heats up quickly, within a minute and straightens with little effort. BIO IONIC Onepass impresses you when seeing the results that make your hair sleek and comfortable.


  • Patented silicone speed strips prevent the hair from bunching up in the iron or slipping out before you get to the ends. This means less restyling of sections.
  • BioCeramic heaters recover instantly between each use making this iron’s heat more consistent.
  • One-inch plates allow versatility in styling. You can also use it for curls and flips.
  • NanoIonic mineral plates use high concentrations of negative ions and infrared heat for shiny, brilliant hair.


  • Users may not like the way the silicon grips the hair.
  • Those with coarse hair may find that the 400° doesn’t provide the desired results.
  • Keratin treatments often need an iron that will work at a 450° temperature.
  • Standard 1″ plates, meaning thicker and/or longer hair may take longer to style.

6. Best For Curly Hair: Karmin G3 Salon Profession Flat Iron


Everyone looks for ways to save time in the mornings, but that doesn’t mean you have to skimp on your beauty routine. The Karmin G3 Salon Profession Ceramic Flat Iron can be a huge timesaver. It’s the hottest flat iron on our list, but also the fastest heating. The 30-second flash heating takes about 30 seconds. There are temperature settings for all types of hair, ranging from 250° to 460° Fahrenheit.

This professional-grade flat iron is made with Karmin’s Advanced 100% ceramic and tourmaline plates.

The tools do not create any problems with the tourmaline ceramic plates, and the plates don’t pull your hair. The very durable hair straightener is Karmin which makes you more accessible when using it.

7. Best For Shine: xtava Professional Infrared Hair Straightener


The plates are a little different on the xtava Pro-Satin Infrared Straightener. The ceramic tourmaline plate is 2 inches wide on the bottom. Their upper plate utilizes Xtava’s dual plate technology to maintain even heating as you style your hair. The larger plates allow for larger sections to be styled at a time and can be a great time saver for those with longer and/or coarser hair.

Infrared technology allows for less stress to the hair cuticle by heating it from the inside, locking in moisture. More moisture in the cuticle means less frizzes and more shine while maintaining the health of your hair.

The advanced microprocessor keeps even heating throughout the plate, eliminating pesky hot spots from the iron. The LCD screen allows you to choose settings between 265° and 445°, at 10° increments. Since you always want to use just enough heat to avoid hair damage, this temperature precision lets you find just the right balance.

The flat iron has 10 temperature settings that make you more comfortable to use based on your hair type. The temperature range from 265°F to 300°F is perfect for fine delicate hair, for normal hair the temperature is from 300°F to 380°F and for thick/coarse hair the temperature is from 380°F to 445°F.

The Pro-Satin heats up in about 90 seconds. The one-hour auto-shutoff gives you peace of mind that you will never leave the iron on all day. On the base of the straightener, there is a pullback switch to lock the plates shut for storage and travel.

This will keep the plates from shifting. The 8-foot cord connects with a 360° swivel for more room to move around and fewer twists and knots in the cord.

Izutech is on a mission to make the best flat irons in the world. If this iron is any indication, they are well on their way.

9. Best Multipurpose Use: HSI Professional Glider Hair Straightener

HSI Professional 1 Ceramic flat iron uses the same 100% True Solid ceramic and tourmaline plates and infrared technology as the other model. The heat balance microprocessors still monitor the plates to provide consistent, even heat through the top and bottom plates.​

Healthy, shining hair comes from the infrared heat, sealing the moisture into the cuticle. However, this unit is not quite as powerful.

  • The adjustable temperature dial is not as precise as the electronic control and LCD screen.
  • The flat iron plates are only 1″ wide.

10. Best For Thick Hair: CROC Classic Flat Iron


If you’ve used other hair straighteners in the past, the Croc Classic Straightener may look a little, well, weird. Form and function came before the aptly named device, and once you see all this iron has to offer, you won’t mind. The odd shape allows the digital temperature readout to be in plain view on the handle so you know the exact settings. If you have thicker, coarser, or longer hair, you will appreciate the ergonomic design.

It’s easier to hold and use and has a nano-silver coating to keep the handle cool. Your hand is comfortable, no matter how long it takes to style your hair.

But the Croc Classic Straightener is more than its reptilian appearance. The 1 1/2-inch titanium ceramic plates deliver smooth, silky hair. The Nano fine ceramic heating element eliminates hot spots so you can be sure each stroke is consistent. With temperatures up to 450°, there is a setting for every hair type and texture.

How To Choose The Right Professional Flat Iron?

How To Choose The Right Professional Flat Iron Photo

Some professional flat irons can be an investment so how do you know which one is right for you? Here are a few things to consider as you choose your next flat iron.

Know Your Plate Materials

Today’s flat irons have come a long way since the Teflon days. Plate function and heating are the most important parts of iron. Plates make the difference between a good iron, a great iron, and a fantastic iron. Ceramic plates offer smooth even heating. Some plates are 100% ceramic, offering some of the most optimal heat, and others are just ceramic coated. A combination of ceramic and another material is very common.

Titanium plates are often a combination of titanium and ceramic. One of the smoothest metals, titanium conducts high heat very well. There are even gold plates for even heat and luxuriously smooth passes. Tourmaline is another component of many professional flat irons. Tourmalines are precious gemstones that are ground up very fine and combined with other plate materials to emit negative ions.

Plate Size

Another considerable element of flat iron is plate size. There are many different sizes of flat irons available on the market; you choose the various sizes based on your hair type. A small plate flat iron is perfect for short hair; on the other hand, the large plate size is easy to use for long hair. So you must know to understand the hair type which you have.

Ionic Technology

By now you’ve used or heard of a hair styling tool that promised ionic technology of some type. There are lots of different buzzwords made up by ad campaigns, but they are all talking about the same thing. An ion is an atom that has lost or added an electron. Positive ions have lost an electron and negative ions have gained an electron.

Styling tools that generate negative ions will break larger water molecules down into smaller water cuticles. This allows the heat to dry the hair faster. Negative ions also seal hair cuticles for a smoother finish with less frizziness and flyaways.

Temperature Control And Variable Heating

Nothing makes or breaks a hair straightener more than the operating temperatures and variations. Choosing a flat iron that allows you to change the temperature settings allows you full control of your styling experience.

It allows you to pick the best temperature for your type and texture of hair, therefore speeding up your styling routine. Temperatures that are too high and too low can lead to damage.

Too high means you are at risk of heat damage, but too low means you are likely to make multiple passes on the same section. Multiple passes can do as much damage as high heat! If you want an iron to perform at-home Keratin treatments, it is usually suggested that the iron can go up to 450°.

Other Considerations:

  • How heavy is the appliance?
  • Is it easy to see what the temperature is?
  • Do I need a smaller/larger plate size?
  • Can I also use it to make waves, flips, and curls?
  • Will it automatically shut off if I forget about it?
