The best diffuser for curly hair

After years of seeing pin-straight hair everywhere from runways to PTA functions, curly hair is bouncing back into the spotlight. And it’s easier to achieve than ever, thanks to the modern hair-dryer diffuser. The handy blow-dryer attachment is typically round and cuplike, with finger-like vents that gently diffuse air over a large surface area to dry curly hair and tame frizz. For curly girls, it’s as essential a beauty tool as your trusty hairbrush and curling iron.

“Diffusers are great for anybody with wavy, curly, coily, and kinky hair textures to enhance curl, dry curl, stretch curl, or reduce shrinkage,” says Gregory Patterson, celebrity hairstylist and DIY expert for Sally Beauty. A curly hair diffuser can also be used to help set hair when doing twist-outs, rod sets, or wave patterns. For the smoothest effect, use low heat settings and lower speeds. “This helps to allow the curl pattern to form and dry in a much more gentle way, which your curls will always love,” he says.

Before you start investigating how to use a hair diffuser, browse our list of the best hair-dryer diffusers available. We tapped hair experts for their favorites and read through hundreds of reviews from curly-haired folks like you. We also tested many of them out to see how easy (or difficult!) they were to use and whether or not they lived up to the hype. We managed to narrow down our picks to 15 diffusers truly worth your money. One thing to pay attention to: Some of our favorite diffusers come prepackaged with a blow-dryer, while others are sold separately and work exclusively with a paired blow-dryer.

It boasts 360-degree airflow, which surrounds your curls and speeds up drying time without leaving your hair looking parched. To kick your look up a notch, follow these curly hair tips that’ll help you style your hair to perfection.

Dyson Supersonic Diffuser via dyson.com

Dyson Supersonic Diffuser

Best for thick hair

Like most Dyson hair products, this diffuser will give you a salon-worthy blowout. You get the added benefit of longer prongs, which provide more control while drying and help those with the thickest curls manage drying time and styling.

Highlights:

  • One-year warranty
  • Three color options

Ion Luxe Supercharged Hair Dryervia sallybeauty.com

Ion Luxe Supercharged Hair Dryer

Best for all types of hair

This small powerhouse is Patterson’s top pick. “I love it for its innovation in design—the finger air vents have been angled so that the diffuser airflow blows into the center of the curl section rather than the traditional airflow on the surface,” he says. “The hair closest to the root gets dried at the same time as the outer surface of the hair, which helps to create a more uniformed curl with less frizz because you will manipulate the curls much less.” Amp up your hair’s curling power by swapping out your regular shower routine for a combination of shampoo for curly hair and conditioner.

Highlights:

  • Sold with blow-dryer
  • Magnetic diffuser attachment is easier than most

Harry Josh Pro Tools Pro Dryer 2000 Diffuser

Best for travel

This compact diffuser by celebrity hairstylist Harry Josh is small but mighty. It’s designed to not only dry curly hair but also distribute heat evenly so you don’t have random dry spots while other areas are still damp. Note that it fits only the stylist’s hair dryer, so if you don’t use the Harry Josh Pro Dryer 2000, you’ll need to pick a different diffuser option.

Highlights:

  • Small enough for travel
  • Even heat distribution

Revlon Inrared Heat Hair Dryervia amazon.com

Revlon Infrared Heat Hair Dryer

Best for versatile styling

If you prefer curly hair only some of the time, your best bet is a blow-dryer with several attachments—including a diffuser for curly hair. We love Revlon’s hair dryer for the tourmaline ionic technology, which helps smooth away frizz. Take your pick of attachments, based on your ideal style for the day. Want smooth hair worthy of a straightening iron? Use the concentrator. Creating soft, bouncy curls? The diffuser gets the job done while maintaining volume. Nearly 22,000 five-star reviews sing its praises. “I need a dryer with a really good diffuser for when I wear my hair curly,” writes one reviewer. “This totally fit the bill! Airflow is strong, but the diffuser prevents it from straightening out the curls.” Don’t need a diffuser? Try our editor’s favorite styling tool, the Revlon one-step hair dryer.”

Highlights:

  • Sold with blow-dryer
  • Ionic technology reduces frizziness

T3 Fit Diffuser via nordstrom.com

T3 Fit Diffuser

Best for coils

Though it doesn’t quite match Dyson’s cult status, the T3 brand has a great reputation for delivering quality hair tools like this sleek and affordable diffuser. It’s meant to be used exclusively with the T3 Fit Hair Dryer (sold separately), but we tested it out with different models—it worked on some, not others. It’s worth a try, but be sure to consider the return policy before you commit to trying this diffuser on another brand’s hair dryer. The product was created to lift and separate hair for added body, so even heavy curls or coils won’t be weighed down. Pro tip: If frizz is an issue, use a frizzy-hair product before diffusing your curls.

Highlights:

  • Ideal for tight coils
  • Lifts and separates curls

You’ll also have maximum styling ability, so you get to decide whether you want to target specific areas or concentrate on a few big, bouncy curls.

So read the description and measurements carefully before ordering. And if you want to try a completely different look, check out this hair straightener comb.

Drybar The Bouncer Diffuser

Best for natural-looking curls

If you like to look like you woke up this way, step away from the straightener brush and toward this  diffuser instead. The Bouncer is made to create springy curls that look polished but not too done. Drybar products have a massive following for a reason—they almost always produce perfect results, even if you’re not a styling expert. Many reviewers rave about its curl-defining ability, and most (though not all) report that it fits their blow-dryer, no matter what brand or model.

And at $10, it’s a great way to test out a new tool to see whether or not it works with your curls or coils. One thing to note: It’s specifically made to fit the Bombshell blow-dryer.

T3 SoftCurl Diffuser

Best for fine hair

Curly hair isn’t always thick or kinky. For fine or harder-to-manage hair, you need a diffuser that will enhance curls softly to prevent breakage while lifting and separating to create volume. Though this product is compatible only with the T3 Cura or Cura Lux blow-dryers, the pair is worth the investment for its ability to avoid damage from overdrying. On that note, here’s a hairstylist tip to avoid further damage: When you scrunch your curls, be extra gentle to prevent breakage or split ends.

Highlights:

  • Two color options
  • Ideal for thin, fine hair
