For curly hair, there's often a love/hate relationship with hair dryers. Sure, they can speed up your drying time—but the fast, hot winds can leave your curls feeling dry and looking less than defined. Enter diffusers: a curly girl's hero accessory to blow dryers. These handy, bowl-shaped attachments distribute the air throughout your hair so that your curls can dry more evenly, resulting in more defined curls. According to Aeleise Ollarvia, the cofounder of Black Girl Curls, a diffuser makes all the difference. "A diffuser is a great, portable way to take curls from wet to dry with minimal flyaways," she explains. "It can also enhance volume during the drying process if desired."
We conducted hours of research on the best diffusers for curly hair, evaluating each model by its design, benefits offered, and what type of hair it works best on. After consulting with a haircare expert and considering dozens of options, we landed on the following best in show.
Best Overall
DevaCurl DevaFuser
Unique design
Smoothes hairs
Ceramic lining
Not compatible with all hair dryers
Type: Diffuser
You’re probably familiar with the curl innovation of DevaCurl, so it’s no surprise that the brand would have a one-of-a-kind diffuser made with curly hair in mind. The ceramic inner core preserves moisture to ensure shinier, sleeker-looking curls. Plus, the wide, hand-like head delivers 360 degrees of airflow to shorten your drying time. Just keep in mind that it takes longer to dry hair.
Best Budget
KingKam Silicone Hair Dryer Diffuser
Affordable
Travel-friendly
Compatible with a variety of dryers
May collapse while using
Type: Diffuser
You don’t have to break the bank to get a quality diffuser. This collapsible travel-friendly blow-dryer attachment offers easy storage, funneling and softening the airflow of your hairdryer while also collapsing to a convenient size.
Best for Volume
Drybar The Bouncer Diffuser
Adds volume
Dries bigger sections
Lightweight
Reviewers note diffuser can fall off
Type: Diffuser
This convenient diffuser gets major points for its large shape that’s able to dry big sections at a time. The circular shape cups your hair to distribute heat from roots to tips for great shape and volume. It’s also surprisingly lightweight so that every wash day doesn’t also have to be an arm workout.
Best for Travel
Hot Sock The Ultralight Diffuser
Travel-friendly
Lightweight
Compatible with a variety of dryers
Not as much control as traditional diffusers
Type: Diffuser
No room for your standard diffuser in your carry-on bag? This Hot Sock diffuser is the next best thing. While it doesn’t feature fancy prongs, it conveniently glides over the nozzle of your blow-dryer to reduce heat damage, limit flyways, and promote more defined curls.
Best Compact
Chi 1875 Series Advanced Ionic Compact Hair Dryer
Lightweight
Three heat settings
Includes diffuser
Pricier than other options
Type: Dryer + diffuser
When you want all of the bang of a quality hair dryer with less of the bulk, this compact ionic dryer is a great solution—and of course, it comes with a handy diffuser attachment. With three heat settings and two speed settings, you can control the amount of heat you subject your hair to while diffusing the airflow for a more precise drying experience. This is pricier than other options on our list—but you're getting a whole drying system, not just an attachment.
Best Splurge
Dyson Supersonic Hair Dryer
Unmatched styling capabilities
Reduces damage
Includes diffuser
Pricier than other options
Type: Dryer + diffuser
This Supersonic hairdryer is quite the splurge, but users who love it say it’s worth every penny. Aeleise says that this dryer “has power and heat but doesn't displace the hair even on the highest air setting. It's game-changing because the hair can dry in half of the time.” Its technology takes blow-drying one step further by doing the work of your favorite heat protectant and guarding your hair against damage for 75% increased smoothness and 132% decreased flyaways—no matter the humidity. Yes, it's expensive, but it's also won over fans who swear by its results, so we think it's worth the spend.
Best Classic
Conair InfinitiPro Hair Dryer
Lightweight
Includes diffuser
Three heat settings
Noisy
Type: Dryer + diffuser
There’s a reason why Conair is celebrated for making quality hair tools—they just get it right, and this classic hairdryer is no exception. The ceramic technology makes for safer drying, and you can also use the cold shot when you want to avoid heat. The diffuser also has prongs with multiple lengths so it can evenly distribute air through thick hair.
Best Smoothing
Revlon Salon Infrared Hair Dryer
Minimizes flyaways
Adds shine
Includes diffuser
Reviewers note diffuser can fall off
Type: Dryer + diffuser
This blow-dryer and diffuser set was made with humidity in mind. With infrared heat technology and a diffuser with widespread prongs, you reduce your risk of over-drying your hair. The results? Smoother curls and enhanced shine.
Best Adaptable
Hairizone Hair Diffuser Adaptable for Blow Dryers
Compatible with a variety of dryers
Comes in various colors
Can break easily
Type: Diffuser
When you buy a diffuser that doesn’t come with your blow-dryer you can run the risk of it not fitting—but not with this adaptable head. With a quick squeeze, it can adjust in size to fit 90% of blow-dryers on the market. Use the diffuser for a sleek finish.
Best for Thick Hair
CONFU Hair Dryer With Diffuser
Longer prongs than other options
Lightweight
Three heat settings
Noisy
Type: Dryer + diffuser
Having a diffuser sounds like a great curly-haired solution unless your hair is too thick for tiny prongs to penetrate. That’s why this diffuser is such a standout. It has extra-long prongs that can reach the roots of thick hair, and the convenient, lightweight dryer is ergonomic for comfortable styling. For tighter curls, Aeleise offers her advice for maximum definition and flyaway-free diffusing, “When using a diffuser on tighter curls do not put it into the hair. Hover it over the hair 4 to 6 inches like a portable hood dryer. Move it in the direction the hair grows, root to end, not end to root, to reduce the possibility of frizz. Don't put your hand in your hair either till the hair is 60% to 75% dry.”
Best Hair Tool Set

Reduces damage

Hair can get sucked into dryer
Type: Diffuser + dryer
This diffuser sets itself apart from the pack for its unique design that has a large surface area—making for quick drying and faster results. The removable diffuser is evenly spaced for added definition, texture, and increased volume.
Best Hooded Dryer
Glow by Daye Soft Bonnet Hood Dryer Attachment
Even heat distribution
Compatible with a variety of dryers
Affordable
Testers note its not comfortable to wear
Type: Hood attachment
Now, this isn’t exactly a diffuser, but the even distribution of the air gives you all of the benefits of a hairdryer with the convenience of an attachment. It’s great for setting roller styles or twist-outs, but it can also be used on wash-and-go styles for easy, effortless drying. Plus, the flexible material fits virtually any blow-dryer.
Best for Fine Hair
T3 Soft Curl Diffuser
Volumizes and enhances
Affordable
Only compatible with a T3 blow-dryer
Type: Diffuser
This do-it-all diffuser works for both curly and coily textures, and for all hair types. However, it’s especially choice for those with finer strands. The vented extensions evenly disperse heat, helping to add volume, all while defining your spirals in the process.
Best Multitasker
Shark FlexStyle Air Styling and Drying System
All-in-one tool that’s great for creating a variety of styles
Minimizes heat damage to hair
It's an investment
Type: Diffuser + dryer + attachments
This isn’t a diffuser, it’s not a dryer, and it’s certainly not your run-of-the-mill hot tool. There are not one, not two, but three different attachments included: a blow-dryer head, two different size curling wraps, a round brush, and a unique, flower-shaped diffuser. The diffuser is noteworthy in and of itself, with retractable and extendable prongs that help shape your curls to perfection. Plus, this also gives you the option of wearing your hair smooth if you want to blow it out, or adding back waves with the curl wraps. Not to mention that it measures and regulates the air temperature a whopping 1,000 times per second, helping to drastically cut down on the likelihood of heat damage.
What to Look for When Shopping for a Diffuser for Curly Hair
- Size and Shape: When you’re buying a blow-dryer that already comes with a diffuser attachment, you’re in the clear. But if you are searching for an attachment, Aeleise says, “make sure the one you purchase fits securely on your preferred handled dryer. This will reduce fumbling and possible frizzing of the hair.”
- Your Hair's Thickness: Thick hair obviously needs a bit of assistance to dry quickly, so those with thick hair should choose a diffuser with longer prongs that can penetrate your curls and coils to dry your hair at the root.
