I'm Obsessed With Protecting My Fine, Damaged Hair—These Flat Irons Pass My Test

As a millennial, I have lived to see some of beauty's greatest hits when it comes to trends, from butterfly clips and frosted pink lipgloss to messy buns and, of course, the era of stick-straight hair. And as an aspiring beauty editor, I followed the trends almost religiously. I woke up every morning before school and refused to leave the house until every strand of hair was straight—I even had a double mirror to check the back. (My mom helped, too). Looking back, I cringe at the number of times I would straighten the same section of hair, ultimately damaging my already fine, soon-to-be-highlighted hair. 

As I've gotten older and continued to educate myself in the beauty industry, I've come to one conclusion: In order to achieve your beauty goals, you have to first understand what you're working with. For example, I now understand I have thin and fine hair, which means a little product goes a long way. I understand that my color-treated hair can be easily damaged, so I opt for hydrating hair masks and supplements that promote hair health and growth. I also understand how to properly use heat tools to achieve the look I want without causing permanent damage. Though avoiding heat is the greatest gift you can give your hair, I've realized you can't avoid heat forever—some days, you crave that flat-ironed look or a soft wave. 

How to Use a Flat Iron While Minimizing Hair Damage

I have mastered the art of flat-ironing hair while maintaining its health—yes, it can be done. I follow a few simple guidelines:

1. Keep the heat on the lowest setting

2. Always use a heat-protectant spray 

3. Invest in flat irons that evenly distribute heat throughout the hair

And let's be real—it can be scary to test which flat iron is best for damaged hair because it's a major risk to your hair's health. Fortunately, over the last decade or so, I have put in the dedication and research to prove you can indeed use a flat iron on fragile hair.

GHD Platinum+ Hair Straightener Ceramic Flat Iron

Best Overall

This flat iron has been my go-to for the last several years. Recommended by celebrity hairstylists Ryan Trygstad and Mark DeBolt, who own Mark Ryan Salon, this flat iron monitors heat 250 times per second and does not go above 365º to ensure you can't damage your hair.

Customer review: "Love it! I was able to achieve salon[-quality] silky hair without the heat style smell. It seemingly truly self-regulates the temperature needed for your hair without you having to make any adjustments. Plug it and use [it]. That's it."

Customer review: "I absolutely love this straightener! So easy to use for curling or straightening my hair (I have long wavy/frizzy hair) and heats up so quickly. I would definitely recommend it to anyone."

Dyson Corrale Straightener

Though this one errs on the pricier side, your hair health is priceless, and Dyson's straightener is designed with flexing plates to gather your hair for more control so you can get the look with less heat and less breakage.

Amika The Conductor 1 Inch Precision Geranium Flat Iron

I love this flat iron when I want to create a beach wave. Because it's only an inch, it gives me more precision in creating the shape I want, and therefore, I don't have to repeatedly go over a specific area.

Revlon Salon Straightener Copper + Ceramic Flat Iron

I have to be honest—I was skeptical about this one because of the price. It was too good to be true. Because this is designed with advanced copper-and-ceramic plate technology, it helps reduce over-styling through even heat distribution.

Customer review: "I bought the 1.5" flat iron to reduce the passes and therefore heat on my shoulder length hair. I especially like the comb attachment to keep all the hair smooth as it glides down the length. So far, I am very pleased, especially at the reasonable price."

L'Oréal Steampod Flat Iron & Styler

Behold the power of steam. This flat iron has an innovative stream technology that surrounds the hair with steam—though it never gets the hair wet—to style twice as fast, leaving the hair ultra smooth. The best part? The steam allows for 91% less breakage than your average heating plates.

Customer review: "I was blown away at the salon quality hairstyle I achieved after using this product one time. Not only was the whole process super fast, my hair was also sleek and shiny. I cannot recommend it enough."

BaBylissPro Nano Titanium Prima Ionic Straightener

Ceramic plates are largely considered the safest for damaged hair, but the titanium plates and outer shell on this iron keep it from warping under high heat, so it won't catch or snag your hair over time.

Customer review: "I loved how it was easy to use. It comes with gloves that help with handling the hair and the flat iron itself. No snagging my hair, leaves the hair feeling hydrated [but] not burnt. Would definitely buy other products from this brand."
