Best Flat Irons of 2024

We Tested and Reviewed the Top Flat Irons for Healthy, Damage-Free Straightening

Celebrity stylist, Beau Dieda, testing and reviewing the top hair straighteners on the market.

As a hairstylist with 20 years of experience, I’ve had many clients ask if I can repair damage from dyeing, overprocessing, and other salon treatments. Thankfully, I’ve been doing this for a long time, so I can help transform their dry, damaged hair into soft, silky strands.

But I’ll let you in on a secret: it’s all about having the right hair tool. Your hair frames your eyes, lips, and smile, so it’s not surprising that healthy-looking locks can shave years off your appearance.

But here’s the big thing most of us forget. You only get one shot at a first impression, so what does your hair say about you when that happens? Will it complement who you really are?

Sometimes, we just don’t have the time to dress to impress. But you don’t have to settle for a bad hair day. Modern hair straighteners have come a long way with impressive features that make styling faster and easier.

A good straightener makes your hair sleek, less frizzy, and stylish. A bad straightener can fry your hair and cause damage. The main culprit behind damaged hair from straighteners is heat. Too much heat burns the hair cuticle, causing irreparable harm. Yet, properly used heat brings luster to your hair.

This is why having an excellent hair straightener is a great ally in your corner — so it’s worth doing a little research before spending your hard-earned cash on one. But we know how time-consuming this process can be, so we researched, tested, and reviewed the “most raved about” hair straighteners on the market for you.

As a stylist with two decades in the haircare industry, I know firsthand that having the right tool is vital. Plus, current technology on hair straighteners is better than ever. Why not take advantage of it?

Our top choices are the champions of the bunch, ready to help you achieve silky smooth hair and gorgeous beach waves or get you out the door faster on those hectic mornings.

Here’s What To Look For in a Modern, Damage-Minimizing Hair Straightener

1. Floating Ceramic Plates – Floating plate technology allows the plates to tilt at varying angles in response to the tension you apply when the straightener slides down your hair. It prevents snagging and breakage. Ceramic plates distribute the heat evenly, reducing the risk of hot spots that can fry your hair.

2. Adjustable Heat Settings – Hair varies in thickness, and yours may need more or less heat than other people. Some of the best flat irons on the market have digital displays that allow you to see the exact temperature, which helps you avoid damage.

3. Infrared Infrared Technology – Infrared light penetrates deep into your hair cuticle, sealing in its natural moisture and adding silky shine.

4. Versatility – The best ones can straighten, curl, or add beach-style waves to your hair.

5. Dual Voltage and 360° Swivel Cord – Flat irons that have dual voltage capability and a 360° swivel cord provide effortless styling anywhere, anytime.

6. Steam – This NEW tech is a game changer. New hair straighteners in 2024 are beginning to use “steam-tech” because it combines heat and moisture to nurture health. This technology helps prevent the dryness and damage associated with traditional dry heat straighteners.
Steam ensures your hair remains hydrated and pliable during the straightening process, reducing the number of passes needed and minimizing potential damage. As a result, your hair retains its natural strength and shine, making steam straighteners a preferable option for healthier, straightened hair.

Our Testing Process

In our pursuit to uncover the best hair tools, we enlist the expertise of professional hairstylists with decades of relative experience. Their insights are instrumental in developing a comprehensive evaluation framework, focusing on what truly matters in a high-performing flat iron. 

Our criteria for assessing each flat iron were both thorough and varied. We looked closely at the features offered, particularly the range of heat settings, to determine each tool’s effectiveness and versatility. The integration of these flat irons into daily styling routines, straightening performance, and the overall quality of the hairstyles achieved were key factors in our evaluation.

We didn’t overlook the details that enhance user experience, such as the weight and cord length, the placement of buttons for ease of use, and how versatile each flat iron was when it came down to creating curl and wave styles. 

After testing each flat iron, we compiled and analyzed the data to identify the standout models. This process helped us not only to discover the best performing flat irons but also to spotlight the top picks for specific needs, ensuring you find the perfect tool for your styling preferences.

Our second option, the Dyson Corral, stands out for its versatile features. 

A noticeable downside: many users report this cordless flat iron doesn’t hold charge for very long, which can slow down the styling process. Others find its weight and bulkiness make the handling and storage less convenient. 

The Dyson Corral straightener offers commendable hair straightening capabilities, earning the second spot on our list.
