What To Consider In A Curling Iron For Fine Hair

“People with fine hair need to be very careful when working with a curling iron,” says Dorram. This means using lower temperatures and opting for barrels made with certain materials. Here’s what else to keep in mind.

Heat Settings

Dorram says that fine hair is more responsive than thick hair, which means it’s important to find an iron with multiple settings. “Look for irons where you can adjust and control the heat setting by degrees, versus only on/off or low, medium and high,” says Hayes. “This gives you much more control over exactly how much heat your hair is being exposed to.”

For fine hair, always start with low heat. “Those with fine hair do not need to turn up the heat to the highest heat setting,” says Ju. Keeping the temperature on the lower end won’t just protect your strands—it may encourage a better curl. “If the iron is too hot, it can actually have the opposite effect and prevent the hair from being able to hold shape, making it more limp because it can’t handle such high heat,” says Hayes.

Materials

All of our experts recommend a ceramic barrel for fine hair. “Ceramic plates distribute the heat more evenly than titanium, so there are no ‘hot spots’ on the iron that could cause more heat to be applied on one spot of your hair than others,” says Hayes. “This minimizes potential damage and produces a more even curl.” Titanium barrels can sustain higher temperatures for longer, she adds, but it’s not something that fine hair needs. Ceramic barrels have another benefit, too. They help smooth the hair by closing the cuticle and minimizing frizz for a glossy finish.

Barrel Size

Barrel size determines curl size, so the bigger the barrel, the looser and larger the wave. But hair length and texture can also steer you toward a bigger or smaller barrel. “Those with fine hair may struggle with their curls not holding the shape or lasting as long,” says Hayes, so you might want to opt for a smaller barrel size. “If you start with a tighter curl, knowing that it may fall and loosen fairly quickly, then you are more likely to end up with the desired result of that perfect wave,” she says.
