While they might not look a whole lot different to the untrained eye, today's curling irons are a lot more effective than their decades-old counterparts. Still, fine hair is notoriously hard to style with heat tools, even with today's advancements. The best curling irons for fine hair have adjustable temperature settings to avoid frying fragile, thin hair.
"Temperature is key," celebrity hair artist Sally Hershberger tells Byrdie. "Fine hair is more susceptible to heat damage, so finding one that allows you to keep a steady temperature is major—310 Fahrenheit (F) is ideal for fine hair."
We conducted hours of research on the best curling irons for thin hair. We tried some of the top-rated models out there, our testers taking note of heat settings and how easy the curling iron was to use. Our team then combined these results with our own research of fan-favorites plus stylist-recommended picks to create this list.
Ahead, find the best curling irons for fine hair.
Hot Tools 24K Gold Marcel Curling Iron
Heat sensor technology
Not ideal for beginners
"I like the Hot Tools Professional 24K Gold Marcel Iron," says Hershberger. "It's lightweight, creates a great curl, and can hold a steady temperature at 310 F that won't damage the hair." As its name suggests, this 1-inch wonder is coated with 24-carat gold to deliver optimal shine.
The brand's Pulse Technology senses heat loss and then restores it to the barrel. And unlike traditional spring irons, the marcel-style clamp offers more control when styling. (If you've never used a marcel iron, it'll take a little practice, but before long, you'll be a pro.) Not only that, but Hot Tools backs this iron with a seven-year warranty.

Conair Double Ceramic 1-Inch Curling Iron
Moderate heat range

With a moderate heat range that doesn't go above 375 F, Conair's budget-friendly Double Ceramic Curling Iron was designed with fine hair in mind. Though as Hershberger notes, you're wise to keep it around 310 F. The non-tapered ceramic barrel evenly distributes heat while helping to smooth frizzy hair.

What to Look For
When it comes to curling finer hair, hairstylist Shelly Aguirre stresses the importance of choosing a tool with a fully ceramic (read: not just coated) barrel. “You need to have even heat distribution from the top to bottom of the barrel,” she says. “If the barrel isn’t evenly heated, you’ll tend to go over the section more times than necessary because you’re not getting the results quick enough”—thus, leading to heat damage, which is definitely not beneficial to anyone with fine hair, which tends to be much more fragile.
To keep fine, limp hair looking healthy and vibrant, Aguirre also recommends looking for an ionic curling iron. “Negative ions will help make the hair shiny and less frizzy due to the simple fact that negative ions close down the cuticle,” she says. “Your cuticle lays like shingles on a roof, so ‘laying them down’ will increase the shine and offer a healthy overall look.”
Per Pucciarello's advice, those with fine hair shouldn’t be using their curling irons at 450 F unless they want fried, damaged hair. Aguirre says that it’s imperative to look for a tool with temperature control so that you can adjust it to fit your styling needs while maintaining a non-damaging temperature range. “You should keep the heat down to around 325 to 350 degrees, so you’re not damaging the hair,” she recommends. “Also, using a heat protectant is necessary and not negotiable.”
What kind of curling iron is best for fine hair?
As Aguirre mentions above, fine hair is more prone to damage than other hair types, so it’s important to look for curling that will keep the hair healthy (but, of course, still work). She recommends a curling iron with a fully ceramic barrel to allow for even heat distribution, ionic technology to keep the hair shiny and frizz-free, and temperature control to allow you to style in a non-damaging temperature range.
She also notes that a quality iron that won’t singe your hair may be pricier, but it’s well worth the investment. “Spending a little more when investing in a hot tool will help in the long run—ask your stylist for the recommendations when it comes to these tools,” she says.
What temperature should a curling iron be for fine hair?
According to Aguirre, those with fine hair should keep their curling irons in the 325 to 350 F temperature range to effectively curl the hair sans heat damage.
What size barrel is the best for fine hair?
When it comes to choosing the right barrel size, Aguirre says it depends on how curly you’d like your hair to be. “The smaller the barrel, the curlier the look,” she says. “This is also dependent on the length of your hair and what look you’re trying to achieve. When in doubt, talk to your stylist and get some advice.”
