These Are the 8 Best Curling Irons to Fake Thicker Hair (Really)

"It's very important to use a curling iron that has a lower heat setting if your hair is fine," Knight says. "Too much heat will damage the hair and make it susceptible to breakage, as well as making it even more difficult to achieve a curl next time you style. Not all hot tools have heat settings. I love the T3 Curl ID 1.25" Smart curling Iron, which not only has nine heat settings but also auto-adjusts its temperature based on your hair texture and condition."

"I love using GHD irons on fine hair," says Clariss Rubenstein, hairstylist and R+Co Collective member. "They're so effective, heat quickly and evenly, and come in a variety of sizes. (Often, you have to use a smaller-size iron for hair that falls easily.) The GHD irons also automatically default to the safe hair temperature of 365ºF and heat perfectly evenly, which helps damage hair much less." 

Leo Izquierdo is a hairstylist and co-founder of IGK Hair Care. He also recommends GHD curling irons, calling them his "go-to" hot tools. "Not only are they sleek-looking, but they also maintain the heat all day in the salon with tons of clients coming in daily, last a long time through wear and tear at the salon, are easy to use and don't have any complicated buttons or instructions, heat up quickly, and have many different sizes so I have options based on my clients' length and density of hair."

This curling iron, although less expensive than many others on this list, performs just as well—if not better—than all of them. Not only does it make my hair look full, bouncy, and shiny, but it creates curls that *actually* last. My hair is stubborn and likes to fall only an hour after I style it. But with this one, it lasts all day.

Another Hot Tools product, this is yet another one of my favorite curling irons to use on my fine hair. It has variable heat settings up to 430ºF (although, I never go past 380ºF so as not to risk damage), a swivel cord, and a 24-karat-gold-plated barrel with a cool tip for holding while styling.

This three-in-one hot tool can act as a curling wand, a traditional curling iron, and a waver. That means it can create bold, defined curls as well as beach waves and bouncy '90s-inspired curls. I love a multitasking tool.

The Dyson Airwrap uses a digital motor to style hair without excess heat. Yes, it's an investment. (A hot tool that costs over $500 is nothing to sneeze at.) However, if you style your hair every day, and you want to do away with as much damage as possible, this might be your best bet. It delivers incredible volume in my fine, thin hair—I use it all the time.

Like the Dyson, this styling tool uses air and regulated heat to create big, bouncy curls (among other styles). Don't take my word for it, though. Trust this customer review: "This is the best hair tool I've ever bought and highly recommend it. I struggle with styling my hair and this makes it so easy and allows me to get the style I've always wanted but could never get. After I used it for the first time, I was asked if I got my haircut. It looked so good, they thought it was done by a hairstylist. I have thin hair and the volume I was able to get with the round brush was beyond my expectations."

"You want something that won't become crispy or flaky," Knight says. He recommends R+Co Outer Space Flexible Hairspray for this step. Just be sure to follow up with another coat of hair spray after you're done curling each section. This will lock in the style and shape.

One more thing: Refrain from touching your hair until it's completely cooled down. "After you curl the hair or add a wave pattern, let the hair cool off before touching it or running fingers through it to allow the cuticle to shut and seal the style," Izquierdo says.

Another tip from Knight is to put your scalp's natural oils to good use. Don't curl your hair after washing it, as it won't hold the shape as well. "I'd say freshly washed hair isn't ideal for curls in fine hair, so make the most of a second-day head," he says. "Touch up a little with dry shampoo first. Then, start the curl process." 

As for a more extreme but "very useful" tip, consider getting a perm. "If you want to sport waves or curls every day and just can't make them stay, a perm is a great way to add some bite and texture into your hair before you begin styling," Knight says. "Modern perms have come a long way since the very drying perms of the ’80s and ’90s. Find a salon that specializes in perm processes, and give it a try. You’ll find the curls you later add in with a curling iron stay in until the next wash!" 

There's another thing all three hairstylists agree on, and that's that heat protection is key, especially when it comes to fine, damage-prone hair. "Heat protectant is so important for all hair types, but especially for fine hair," Knight says. 

As for Izquierdo, he recommends this IGK heat-protectant spray. "IGK Good Behavior Spirulina Protein Smoothing Spray has 450-degree heat protection and should be used before any heat-tool styling," he says.
