Back in the early days of flat irons, cheap plastic parts and metal plates meant irreversible hair damage. After all, as any hair stylist will tell you,
heat is particularly damaging to hair. That said, certain types of straighteners (and certain types of heat!) can limit the amount of harm done to your hair when you straighten it. So, what are the best flat irons that won't damage hair?
If you'd like to
minimize damage from straightening your hair, the first thing you want to look for is a flat iron with ceramic plates, because the ceramic material evenly distributes heat all the way across the plates, so chunks of your hair won't burn because of hot spots. Titanium plates, in turn, quickly conduct heat, which can make for a faster straightening process, but can also expose your hair to higher temperatures that might cause damage.
Keep your eye out for ceramic flat irons with tourmaline-infused plates, as that
material, when heated, produces negative ions that coat and condition your hair while locking in moisture, limiting frizz in the process. Finally, there's infrared technology — a relatively recent hair care advancement. Infrared straighteners use special wavelengths to heat the hair evenly from the inside, protecting your hair cuticles and reducing damage on the outside of the strands.
If you're a little overwhelmed by all this jargon, don't worry. Gathered up below, these are the six
best flat irons that won't damage hair, so you can get the sleekest style possible without all that excess damage. 1 INFINITIPRO BY CONAIR Tourmaline Ceramic 1-Inch Flat Iron INFINITIPRO BY CONAIR Tourmaline Ceramic 1-Inch Flat Iron, $25, Amazon

An easy-to-read LED display allows you to see the exact temperature of the plates, and you can easily adjust the heat level anywhere from 190 to 450 degrees Fahrenheit based on your preference. This flat iron is even built with a unique "C-Sensor" that automatically calibrates the temperature of the plates 30 times per second so the iron stays consistently at the temperature you choose. What fans say: "Best flat iron I've ever purchased! It's super light weight and easy to work with. The infrared light doesn't do any damage to my hair. Amazing!!" 4 Mixcolor Professional Ceramic Tourmaline 2-in-1 Flat Iron Mixcolor Professional Ceramic Tourmaline 2-in-1 Flat Iron, $46, Amazon
To prevent any damage, micro-sensors within the ceramic tourmaline plates of this
flat iron help regulate its temperature so your hair won't be exposed to aggressive or harmful heat. The heat settings can be adjusted from 265 to 450 degrees Fahrenheit, and are easily visible from the dial on the side of the flat iron, eliminating any chance that you accidentally use too much heat on your hair. This set also comes with a heat-safe glove to protect your hands when you're using the flat iron, and a bunch of clips and hair separators for styling individual sections at a time. You'll also get a handy traveling case with this straightener so you can take it with you when you're on the go.

1-inch flat iron is made with ceramic plates for evening heating, and has a touch-compatible heat dial that you can simply swipe up or down to increase or decrease the heat. The temperature range on this straightener spans from 250 to 450 degrees Fahrenheit. And, while this flat iron may lack some of the fancier (and damage-preventing) features of other options on this list, reviewers swear it keeps hair looking healthy, shiny, and straight without damage. What fans say: "I love this straightener! I have naturally wavy, frizzy hair. I am always looking for products or appliances to make it straight without fly-always. I ordered this not know if it work really work. It promises shiny and silky hair and let me tell you that it does just that! My hair looks smooth and natural. It does not make my hair feel damaged and some straighteners do. Soft and silky as advertised!" 6 MONDAVA PROFESSIONAL Ceramic Tourmaline Flat Iron MONDAVA PROFESSIONAL Ceramic Tourmaline Flat Iron, $60, Amazon
At this point, you could probably guess that this
splurge-worthy flat iron also has plates that heat evenly thanks to their ceramic construction. Unlike others on this list, this Italian straightener also has a slightly wider plate than most of the hair tools on this list (1.25 inches in width). According to the manufacturer, the ionic tourmaline-infused plates of this flat iron will restore your hair with 3 million negatively-charged ions every minute you use it. That means your hair will retain more moisture while you straighten it and is less likely to frizz or dry out with repeated exposure to heat. But, don't take my word for it. Hundreds of Amazon fans swear by this model. What fans say: "I have fine, delicate hair. This flat iron does not tear my hair at all. It heats up very quickly. The precise temperature adjustment lets me choose a temperature that will do the least damage to my breakage-prone hair."
