The Best Diffusers for Curly Hair

We know a thing or two about the best diffuser for curly hair. No shade to any other section, but I think it's safe to say that we have a lot of great hair on the WIRED Reviews Team. Our Zoom meetings are full of poppin' curls and mind-boggling volume. But all that gorgeous hair takes work, and luckily, we're no strangers to putting in the extra effort toward styling our hair. Diffuser routines have a learning curve and require a bit of elbow grease, but they can help curls and waves look their very best. Our top picks, like the T3 StyleMax Dryer, work for both hair patterns.
A typical hair dryer shoots a jet of hot air straight out, which is great for adding volume or styling straight blowouts. But a jet of concentrated air can cause waves and curls to poof out and lose their shape. Diffusers—you guessed it—diffuse the air and distribute it evenly, helping to disperse that concentration while still offering volume and faster drying. People frequently use the typical nubby-ended, bell-shaped design to help lift and scrunch their textured hair while simultaneously drying it. This results in a voluminous, styled curl or wave with less frizz. And the diffusion makes the air a bit more gentle on your hair, leaving behind less damage. Some diffusers have longer prongs, a different shape, or more air distribution holes, and some styling products can tweak the final look, but the result is still the same basic concept: enhanced natural texture and volume from root to tip. So long as you're prepared to sweat for it.

Updated April 2025: We’ve added two new diffusers from WavyTalk and T3, updated our assessment of the Bellissima Diffon, and ensured accuracy throughout.

More About Our Hair
WIRED reviewer Louryn Strampe has thick, long, curly, mixed-race hair ranging from curl type 2A to 3A. It's low-porosity and usually dry or damaged thanks to her penchant for bleaching it and dying it neon pink.
Nena Farrell has wavy, fine hair in her natural color with a curl type that ranges from 2B to 3A. Her hair is high porosity and leans toward being frizzy on its own. During this testing window, her hair was only about chin-length.
We've also included some notes from former WIRED reviewer Medea Giordano, who has thick, coarse, long, curly hair that varied in pattern from layer to layer. And some recommendations from editor Kat Merck, who is a fan of straightening her hair and no stranger to heat styling.
How We Tested
To find the best diffuser for curly hair, we tested each dryer and diffuser in this guide on a minimum of three wash days. We tried every setting and attachment, and we compared notes on the diffusers’ different characteristics, weights, and features. We aimed to include a mix of diffusers that will work for multiple hair types and hair routines. See photos below of our hair dried with each diffuser or attachment.
Helpful Information About Diffusing
A proper diffusing routine starts in the shower: Wash, condition, and detangle your hair before diffusing for the best results. Apply styling products while your hair is still damp or wet. Avoid touching your hair or drying it roughly during the diffusing process to minimize frizz.
Temperature matters: The higher the temperature, the faster your hair will dry, and the drier and more frizzy it will be. Conversely, low temperatures can help cut back on frizz, damage, and flyaways, but this can add a lot of time to your drying routine.
Get to know your hair type: Do you have waves, curls, or coils? Is your hair high-porosity or low-porosity? Do you use water-soluble products or are they silicone-based? Do you sleep with your hair protected? All of these will have an impact on the best styling methods. You can find great resources on the curly hair subreddit, the Pattern, and our sister site Allure. YouTube and TikTok also are full of great information, and of course you can ask your hairstylist to teach you more about your hair type. Have fun in the rabbit hole!
Honorable Mentions
Beachwaver Co. Blow-Drying Hair Brush for $189: This cute blow-dry brush has a set of attachments that includes a diffuser. It’s a solid choice if you want both a blow-dry brush and a diffuser, but there are cheaper options if you don’t want the blow-dry brush included.
Our Favorite Products
Every person is different, and it can take some trial and error to nail down the right diffuser routine. Maybe you want to dry your hair fully, or maybe you want to take it to 80 percent. Maybe you want a leave-in, a curl gel, and a hair oil, or maybe you just need a little heat protectant. These are some products we like to use during our own hairstyling routines that might come in handy for yours.
Turbie Twist Microfiber Towel for $20: I like to plop my hair after the shower for a few minutes to absorb some water before diffusing. These microfiber towels are designed to stay put, and they soak up a lot of moisture without drying my hair too much. Others swear by plopping with a T-shirt, but this is what works best for me.—Louryn Strampe
Pattern Leave-In Conditioner for $28 and Not Your Mother's Curl Talk Cream and Gel for $19: I put a glob of leave-in conditioner in my hair after plopping, followed by a palmful of curl cream, and finally a generous amount of gel. This is what primes my natural curl clumps to look their best post-diffusion. It may be too heavy for some curl textures, but this is my favorite method. —Louryn Strampe
Kristin Ess Style Assist Blow-Dry Mist for $12: This is one of the most effective heat protectants I’ve tried that actually cuts drying time—halfway through blow-drying, I can actually tell where I sprayed it and where I didn’t. I wish it were as easy to apply as the Milk_Shake foam primer, below, but the bottle still has a decently targeted spray and the product is lightweight enough not to leave residue. —Kat Merck
Milk_Shake Lifestyling Blow-Dry Primer for $26: This lightly scented heat protectant is meant to prevent color fading and reduce drying time. It doesn’t do the latter quite as effectively as the Kristin Ess, above, and a little goes a long way, but it will shave off a couple minutes and gets high marks for coming out of the bottle as an easy-to-apply foam, so it’s a snap to ensure you’re getting even coverage. —Kat Merck
Davines This Is a Curl Gel Oil for $32: This gentle curl gel oil has been fantastic for my fine hair, helping my curls form and keeping them moisturized without weighing them down or making my hair crunchy. It starts out feeling like a gel in your hand, then transforms into an oil on your hair. It's best to use with a diffuser, though I've occasionally used it on air-dry days with similarly good results. —Nena Farrell
