Hot tools are great for a lot of things—like transforming limp, lifeless strands into red carpet-worthy waves—but keeping your hair healthy traditionally hasn't been one of them. Heat is one of the biggest offenders when it comes to damaging your hair, and if you aren't careful, using too much of it, in any form, can leave your lengths dull, dry, and broken. But thanks to advances in technology in the hot tools category that claim to be better for your hair, we've been left asking: In 2020, are hot tools still really that bad for your hair?

Before we dive in, it's important to understand what "heat damage" actually means. When you put any sort of heat directly on your hair, it creates little holes in the protective layer, which can lead to breakage. "Any kind of heat on the hair can be challenging because we are constantly trying to maintain the hair’s natural moisture balance," says Marco Pelusi, celebrity hairstylist. "Hair tends to mimic whatever environment it is in, so if you are heating your hair up with hot tools it will become hot and dry."

And the more you use them, the worse the situation gets. "Repetitive use of hot tools can damage and break the hair severely—especially chemically treated hair—and can also eliminate the hair sheen on all types of hair," says Frédéric Fekkai, celebrity hairstylist and founder of his eponymous hair-care line. Pros suggest applying the general rule of "everything in moderation" to your hot tools routine, meaning that you shouldn't use any hot tool too frequently, on too high of a setting, or for too long.

Of course, not all hot tools are created equal—especially when it comes to the newer models on the market—and pros agree that some of them are decidedly more harmful to your hair than others. "The hotter the tool, the worse it becomes for hair," says Fekkai, who admits that he doesn't believe any hot tools are particularly "safe" for your hair. "The worst are iron barrels and plates because they are very hot and in direct contact with the hair," he adds.

Aside from choosing the right material, you'll also want to pay close attention to the heat setting you're using. “As a professional stylist, I work with so many different types of hair every day, and can tell you firsthand that they can’t all be treated the same," says celebrity hairstylist Laura Polko, adding that factors like hair thickness, length, and color treatment all come into play. So how can you ensure your hair stays protected while still styling it? It all comes down to choosing the right type of iron for your hair type.

If you've got thick hair, opt for something made from titanium, like the BaBylissPRO Nano Titanium Prima 3000 Styling Iron ($190). Titanium is a lightweight metal heats up quickly and evenly, and doesn't require multiple passes over the same section of hair to get its job done (meaning that your hair isn't spending any extra time in direct contact with the heat). Thanks to its unique, rounded shape, it can help you achieve curled and straightened styles, giving you two tools for the price of one

While you should generally stick to the lowest possible setting that works to style your strands, figuring out what that temperature actually is can be confusing. Next-gen irons with built-in heat sensors, like the  T3 Curl ID Curling Iron ($235), can make this process easier by allowing you to input the specifics of your hair's length, thickness, and color treatment in order to output the correct temperature setting. This, says Polko, results in less damage and better styling results.

No matter what type of hot tool you're using, you'll always want to properly prep your strands ahead of time. "Your hair is like a sponge and will absorb the first thing that is introduced to it, so if you're styling with heat and there's no barrier on the hair, it will simply suck up all the heat," says Pelusi. This process starts in the shower, with a product like SheaMoisture Manuka Honey & Yogurt Hydrate + Repair Protein-Strong Treatment ($11), which combines manuka honey and yogurt to infuse your hair with moisture and breakage-preventing proteins.

Continue your hair-protection process post-shower with some sort of styling spray, like the L'Oréal Paris Advanced Hairstyles Blow Dry It Quick Spray ($7). This one, in particular, can be spritzed on before blowdrying, curling or straightening, and creates a barrier between your hair and whatever heat you're planning to put on it. The result? Healthier hair with a whole lot less damage.
