11 Hair Diffusers for the Best Frizz-Free Curls of Your Life

Bed Head takes diffusing a step further with this innovative diffuser/dryer hybrid, earning it our best overall distinction. Instead of a separate attachment designed for use on a traditional hair dryer, this has everything you need in one handy tool.

It features three different heat settings, as well as two different speeds, so you can truly customize your styling session.

Amazon reviewers consider it their ride-or-die hair diffuser, too. “Best experience with a hair dryer diffuser. I always wanted to use a device that worked fast and effectively — and I found it! I love that it is not heavy to carry, its design will be very convenient for traveling, and my frizzy hair turned out spectacular,” says one 5-star review.

Perfect for both long and short hair, this diffuser features 110-plus air outlets to distribute heat and prevent damage. We love the deeper bowl, too, which allows the dryer to get a better grip on your hair, making your curls even more defined.

Amazon reviewers agree using this hair diffuser always levels up their haircare routine. “My curls are fuller and more defined, and my drying time is cut. I wish I had gotten one of these years ago instead of using the smaller ones that come with the hair dryers,” says one 5-star Amazon review.

This affordable hair diffuser is lightweight, easy to use, and can fit a wide range of blow dryers. But the best part is that it’s collapsible, making it the perfect travel companion. Plus, it comes with a convenient travel bag, so you can take it with you anywhere you please.

“Lightweight, and yet, when expanded, worked just as well as the bulky solid plastic one I use at home. Perhaps better as the entire piece heats up for a quicker dry time,” says one Amazon reviewer. They add it works nicely on their personal travel-sized hair dryer and hotel hair dryers abroad.

This weird beauty product looks similar to a chicken foot, but its unique design is tailor-made for curly hair. It's equipped with an impressive 360-degree airflow and a ceramic inner core that heats up quickly to ensure your hair dries fast AF. It also helps define your curls, add volume, and minimize frizzy hair.

“I love, love, love, LOVE this diffuser! The ‘fingers’ slip into areas of my hair around my head in ways that a traditional diffuser cannot. For example, I can slide it into the curls instead of just scrunching them. It gives me [a] great lift at the roots,” says one 5-star Amazon review.

BIO IONIC's hair diffuser will help you achieve frizz-free curls no matter your skill level. You're in control of your styling routine because this hair diffuser has a turn-dial where you can increase or lessen airflow at the center of the diffuser, depending on how dry you want your curls.

Amazon reviewers agree it fits a variety of hair dryers, including cheap Conairs, moderately priced Rusks, and pricey Dyson Supersonics and Drybar Buttercups.

For example, one Amazon reviewer didn’t want to spend upwards of $150 on a replacement hair dryer just because theirs was acting up. “I decided to try this, and it fits my dryer PERFECTLY. I also love that you can twist it to adjust the vents. My curls look amazing, and I’m so glad I purchased this,” says their 5-star review.

Curly, coily, and wavy hair isn’t always full, and that’s where this hair diffuser comes in handy. Like other hair diffusers on our list, this model helps enhance your natural hair texture with the bonus of creating soft volume and a smooth finish to fine hair.

One online reviewer with fine hair admits they recently lost some hair post-partum, but this hair diffuser helps camouflage their hair loss. “The diffuser really does the job of giving my hair lift and volume. You can’t even notice the hair I’ve lost, luckily, it wasn’t too much. I’m so glad I have this,” says their 5-star review.

You’ll adore this hair diffuser when using a T3 hair dryer, including the AireLuxe, Featherweight StylePlus, and Featherweight 3i models. It’s lightweight and helps distribute airflow quickly to help speed up your drying time, especially if you have textured hair. “I have really curly hair, and this has improved the ease of taking care of it,” says one 5-star Amazon review.

SoftTouch 3 is specifically designed to provide proper styling for soft, defined curls. It features vented finger-like extensions to distribute heat gently and evenly, resulting in voluminous, soft curls.

Plus, other reviewers add that it’s super easy to attach to your T3 hair dryer of choice. To quote their 5-star review, “It took NO effort to put on and took literally 1 second to snap on and off, no precise alignment or hard pressure. It’s the perfect diffuser for my most highly rated pro hair dryer.”

Drybar knows a thing or two about proper heat styling. In addition to controlling airflow for properly defined curls, this one also cuts down on frizz and boosts shine.

Wedding hairstylist Senada Ceka says that this is one of her go-tos's when she’s styling curls for its volumizing effect and shining results.

Amazon reviewers agree that it’s the best hair diffuser on the market for enhancing their curls. “Sure does make the curls curl! My hair was full of body and really made it look like I just left the salon! My curls were just like they were when I was little- bouncy and so pretty,” says one 5-star review.

A bonus: They fit full- and travel-sized Drybar hair dryers and most other blowdryers, too.

An excellent budget buy, this Conair pick offers everything you’d want in a hair diffuser for less than 13 bucks. It works well with nearly any blow dryer and delivers frizz-free curls and waves in a flash.

In fact, one Amazon reviewer says it fits their 15-year-old Conair hair dryer perfectly, so definitely give this hair diffuser a shot, even if you have an older blowdryer.

“I was pleasantly surprised when I received it, and it fits perfectly. It also dries my hair quickly while creating very little frizz,” says their 5-star Amazon review. They add it only takes 10 minutes to diffuse their medium-to-long wavy hair at low heat and low speed settings.

Another favorite of Ceka's, this hair diffuser lifts and separates hair while creating soft, bouncy curls without the frizz. This snap-on attachment fits the BaBylissPRO Volare V1, Portofino, and recently discontinued Luminoso Dryers, while the slide-on hair diffuser is compatible with almost a dozen BaByliss hair dryers.

This pick is easy to use, but it's also great for your hair: It works for just about any hair type to add volume and shine, and it cuts your drying time down.

“This is a critical attachment when blow drying any type of textured hair. Happy days for me, my clients, and the salon,” adds one 5-star Amazon review.

Not one, not two, but three celebrity hairstylists (Cheryl Bergamy, Michelle Cleveland, and Michael Boychuck) that we spoke to for this article all praised the wonders of this hair diffuser from Dyson. This diffusing attachment has extra-long prongs to get deeper into your hair, cutting down drying time in half.

But the true magic of this diffuser lies within its meticulous engineering, which means that it disperses air evenly around your curls for a more defined, frizz-free, and voluminous look.

However, there is one drawback: This attachment only works on the Dyson Supersonic Hair Dryer, which costs a pretty penny (but is totally worth it if you have the cash to spend). Our beauty editor, Nicole Saunders, considers this the gold standard of beauty tools. To quote her recent review, “You can be a complete beginner or a professional hairstylist working on A-listers, and you’d still fall in love with this hot tool like I have.”
