The 13 Best Diffusers for Curly Hair, from $5 to $400
Let us guess: When you dry your hair (with direct heat on your scalp), you get frizzy curls and breakage. And when you air-dry your curls, they pretty much stay wet all day. It’s a major hair dilemma, right? But it’s one that can be easily solved with a diffuser, a handy little attachment that helps dry hair, define curls and reduce frizz. Just pop it onto the end of your blow-dryer and let it do the work for you—just don’t forget to add some heat-protectant serum before starting and to run your dryer on a low setting. Below, 13 of the best diffusers for curly hair, according to reviewers.
1. Black Orchid Hair Diffuser
This diffuser has more than a thousand five-star ratings, so we’re not surprised by its benefits. One Amazon reviewer says, “I love this diffuser! It has completely changed my curls for the better. It also has cut down on drying time because it holds so much of my hair at a time. Will always have this product on hand for life.”
The 360-degree design works to dry your hair quickly from roots to tips. Whether your hair is thick, long or curly, the diffuser enhances your natural strands, minimizes frizz and boosts volume. And thanks to the silicone grip, it won’t fall off the nozzle as you’re drying.
2. BaBylissPRO Nano Titanium Universal Finger Diffuser
This diffuser provides soft, bouncy curls to wavy or permed hair. It gently dries large areas while leaving curls frizz-free—not to mention it’s a pretty universal fit for all hair dryers. One reviewer raves, “[It’s] the best dryer I have ever used on my thick and curly hair. The large diffuser and the light weight of the dryer make drying my hair quick and easy.”
3. The Curly Co. Collapsible Hair Diffuser
The last thing you want to do is buy a diffuser only to realize it doesn’t fit your hair dryer. This silicone tool is built to stretch or shrink to fit any nozzle, which also makes it super portable. “I love this product! I travel often, and I’m always freaking out that the plastic diffuser that came with my dryer will get broken during transit, leaving me to deal with bad hair for my entire trip,” expresses an Amazon reviewer. “This diffuser fits snugly on my dryer, even with my dryer’s somewhat oddly shaped end.”
4. Hot Sock Diffuser
Yup, this weird but useful tool is great for a quick dry, especially if you’re using roller sets. It fits on every size blow-dryer and won’t take up too much room in your bag when traveling. One reviewer has a great tip: “This diffuser sock is great for attaching to the mini blow-dryers supplied in hotel rooms. I used it on low heat and it gradually dried my wavy/curly hair without causing frizz.”
5. Segbeauty Professional Hair Diffuser Attachment
The 114 air outlets and multiple teeth on this one help to distribute heat evenly throughout your curls, which prevents dryness. The attachment also has eco-friendly material while ensuring salon-quality results.
One Amazon reviewer enthuses how it completely changed her curls, saying, “This is the best diffuser I have used. My curls are bouncier and fuller than they have been in a long time. I am a curly hair expert! I have used many diffusers that break, fall off the hair dryer and melt. This is awesome! It covers a large part of your head, which is key, and keeps frizz down. Worth every penny!”
6. KingKam Collapsible Silicone Hair Dryer Diffuser
This lightweight silicone diffuser wants to make traveling easier with its foldable design. For one reviewer, it was the diffuser she’d been searching for. “This is a lifesaver! I [put] this in my carry-on every flight I take. It’s small and lightweight. It gets the job done and pairs well with a travel hair dryer.”
7. Dyson Supersonic Dryer
OK, so if you’re down to pay $400 for a hair dryer, it has to be worth it, right? This quiet tool comes with three attachments, including a curly hair diffuser. It simulates the natural drying process to reduce frizz and help you style your hair with control.
If the features alone don’t persuade you, know that this dryer has more than a thousand five-star ratings like this one: “I LOVE this dryer. I couldn’t be more impressed with how quickly and easily my hair dries to a smooth finish. I have a lot of gray hair that tends to frizz and my hair is delicate and easily prone to heat damage. I waited a long time due to the high cost, but it is worth the money. Especially since it is my go-to styling tool for touch-ups as well. Go ahead and treat yourself, you won’t regret it!”
8. Conair Volumizing Diffuser
Looking to create curly or wavy styles? This attachment helps to dry hair quickly and add volume to your locks. “I never really used a diffuser, but after buying this universal one, I love it! Definitely defines the curls!” says one happy reviewer.
9. BestTrendy Professional Universal Hair Diffuser Attachment
This diffuser evenly dries your hair, protects from heat damage and prevents frizz. Many reviews rave about how easy it is to travel with, including this five-star review: “I like that this dryer has cool, warm and hot settings as well as low and high speeds. The dual voltage and electrical adapters make it ideal for overseas travel.”
10. Drybar The Bouncer Diffuser
The salon known for its blowouts created a diffuser with the curly gal in mind. One Amazon reviewer states, “Love my new Drybar diffuser. Super useful, helps my curls fluff and dry nicely, fits on my blow-dryer, great size and teeth for drying, good price, etc. No complaints. Thanks, Drybar!” (It’s important to note it is specifically designed for the brand’s popular Buttercup blow-dryers, but it can work on nozzle sizes up to two inches.)
11. BIO IONIC Diffuser
The lightweight tool’s 12 air outlets make for fast dry time while providing frizz-free results. It fits on most Bio Ionic dryers (except for the Power Diva model). One Amazon reviewer calls it “The absolute best diffuser I’ve ever had. I recommend this to everyone who likes to use them. I like the way it’s made [so you can open or close the vents].”
12. DevaCurl DevaFuser Universal Hair Diffuser
Not your average diffuser, this tool is designed to surround curls (basically hugging them) at the roots to speed up the drying process and enhance the natural definition. One reviewer raves, “I would recommend this product for [everyone with] curly hair. Lightweight, easy to use and dries my hair like no other tool. I spend 20 minutes maximum drying my hair with DevaFuser. Not to forget the gorgeous curls it creates!”
13. Bed Head Curls in Check
Never mind the attachment, this entire hair dryer is made for diffusing. The unique design adds texture, tames frizz and aims for fast drying with just one tool. One reviewer says, “This dryer is great for curly/wavy hair, easier to use than a traditional dryer with a diffuser attachment, not as bulky. I love it!”
