The strands of curly or wavy hair don’t get jammed or tangled in the Hairizone like they do in some diffusers. That’s because the design is spiral.

Pros:

  • Perfect for travel, inflating, and other uses
  • Can be combined with hair dryer to create a diffuser attachment
  • Dries hair faster and has better airflow than hand or hairdryer
  • Creates soft air flow

The Sindycurls Portable Diffuser is the coolest hair diffuser around. It’s soft enough to be collapsed around your blow dryer and held against your head without falling off, but it’s flat enough to inflate and attach to a bike and be left on your head as you ride.

The SindyCurls diffuser is hollow inside with holes on both sides with a max diameter of 7.5 cm (about 3 inches). The holes are taped with plastic tape to keep hair from coming in. The diameter is smaller than the SindyCurls expansion clip but still larger than a lot of hair dryers.

The SindyCurls diffuser is a silicone rubber bellow that is soft enough to collapse and put in your pocket, but sturdier than rubber. It can be squeezed underwater to make it smaller and flatter. It can be put in a sink to dry without being damaged.

14. Collapsible Silicone Hair Dryer Diffuser

Our rating: 7 / 10

Collapsible Silicone Hair Dryer Diffuser

Check Price on Amazon

Pros:

  • Handy carry case
  • Great travel diffuser
  • Best natural looking curls

Most hair dryers are not ideal for creating curly looks because the barrel is often too wide and thus does not provide the styling control that curly hair needs. However, if your goal is to create natural looking beachy waves or textured curls without too much frizz this diffuser will do the trick. With a bit of patience and a few trial runs you can achieve good looking styles in less time than it takes using a regular hair dryer.

The diffuser features a soft, compact design so it will stand up to frequent travel without taking up much space. It also features heat resistant silicone so it can be safely used with any type of hair dryer including the ones you already own.

Note that the diffuser is not actually made of silicone. Instead, it is designed to last longer and stand up to frequent use compared to competitive diffusers because it has double the BPA-free material that other hair dryer accessories have.

Pros:

  • Easy to carry
  • Good for all hair types
  • Makes drying faster

Cons:

  • Dries out hair if used too much
  • Diffuser easily gets dust and lint inside
  • Some of the velcro comes off easily

The Dovewill is one of the most popular choices for hair diffusers thanks to its effectiveness and low price.

When we want to add volume to hair, we commonly use a hair dryer. Sadly, most of the hair dryers do a poor job at it. That’s where the hair diffuser comes in. It helps add volume to hair by diffusing the air.

Using a hair diffuser takes a little getting used to. It also contributes to faster drying time, so what’s not to love? This one is a store favorite because it’s soft, lightweight, easy to pack in a suitcase, disposable, and very effective.

If you are looking for an almost unbelievable solution to the common problem that all curly girls have of straightening their hair without resulting to heat damage, you should definitely check out the Diane hair diffuser.

I will never go back to heat…loose wave spray works just like the diffuser to give you the same extra long-lasting waves. Do not get me wrong, the diffuser is better and the models I have tried.

I have used many hair diffusers over the years, and the only one that I am willing to use regularly and recommend to my readers and all other curly girls out there is the Diane soft finger diffuser.

Pros:

  • The silicone is very silky and has a good grip for when you get the hang of placing a product like a smoothing cream or gel while it is still in your combo hair dryer diffuser.

Although I’ve seen this not matter for other combo hair dryer diffusers, the silicone in this one moves and with it your product can move if it is a heavier product. It’s nothing too concerning just something to note for your combo hair dryer diffuser product application.

M Hair Designs Collapsible Silicone Diffuser

Check Price on Amazon

Pros:

  • adjustable – Our diffuser is designed with a spring-loaded hypo-allergenic silicone core, allowing you to slip through attachments of up to 1.8 inches in diameter.
  • collapsible – This hair dryer attachment collapses into a compact, flat disc so it can easily rest in your bag or suitcase.
  • lightweight – The diffuser weighs almost nothing, so it's perfect for home and travel use.
  • durable – Our diffuser is comfortable, convenient and eco-friendly!

Cons:

  • Not enough hold – doesn't work well if you have pretty frizzy or fly-away hair – if you have super curly hair it works well
  • Can't use with CHI hair dryers – This is designed to work with a Conair brand hair dryer and cannot be used on a CHI hair dryer, despite what the box may indicate. I tried the CHI hair dryer and it just doesn't fit inside the 1.6 inch opening (it was too big) but it should work fine with a Conair brand hair dryer.

If you want the perfect blowout or a simple style every time right out of the shower, a hair diffuser dryer attachment is a lifesaver!

Pros:

  • Universal Fit
  • Includes travel size for added convenience

It’s hard to believe that a hair diffuser could make such a big difference, but I can tell you that it has truly changed the way I style my hair each day. When I straighten my hair, the curls in my hair are so soft that they look more natural, which is not a look I’ve been able to achieve through other methods.

If you’re going for a more relaxed look, or if you’ve got a lot of frizz, the M Hair Designs Hair Diffuser is a worthwhile investment.

It’s easy to use and it comes with cool air vents at the sides so that you can blow cooler air during hot summer months.

Pros:

  • Can be used for all curl types
  • Easy to use
  • Hair-friendly
  • Not too heavy
  • Great for eliminating frizz
  • Will pass through airline security

DevaCurl’s DevaFuser is, in my opinion, the best diffuser on the market because of its ability to work with all curl types. It is a powerful tool that a lot of customers feel has changed their lives when it comes to styling their curls at home.

The DevaFuser is safe to use on all curl types because of the innovative shape that has its back end much wider than the front end. This feature not only makes it easier to work with, but it significantly reduces the amount of risk that is normally associated with using a diffuser.

The unique design of the DevaFuser helps it to easily move throughout your curls and scrunch them in place. Most customers report that their curls stay perfectly in place after using this tool. It’s also great for eliminating frizz.

Pros:

  • Affordable
  • Super easy to use
  • Great for many kinds of hair
  • Different colors to choose from

The invention of rapid-air technology by Conair changed everything for me and for whoever else loves styling their hair. I used to have a traditional hair dryer, but then I upgraded my hairstyling game with this large diffuser.

I used to spend a lot of time doing the "punny hairstyle," but now I can do that and more with these amazing diffusers. I’m a certified hair junkie, so these are essential for me, and I use them every single day without fail.

They always dry my hair as fast as a traditional diffuser, but they never cause damage to my hair. I’ve absolutely fallen in love with them, and I’ve been recommending them to everybody I know, particularly those of you with curly or wavy hair.

Frequently Asked Questions (FAQ)

Which hair diffuser is best?

It depends on your hair type. The smaller the barrel size, the gentler the curl. Wider barrel sizes make looser curls, seemingly more natural looking. Bigger barrels also make curls on shorter hair, which is nice if you are too impatient to let your hair grow a bit for bigger curls (or you have too much hair and need bigger curls to look nice!).

Round barrels are supposed to make curls that look more natural and less poofy, but I’ve never been able to tell the difference. The big benefit here is that these barrels are easy to grip, so you can use them with longer hair, and still have both hands free to hold the curler around your head.

Some models have very bright colored barrels, which might make it more obvious that you are using a curler, but if you are bothered by that, just get a clear one.

Do hair diffusers really work?

Hair diffusers work like the professionals use to create hairstyles. However, instead of hiring a stylist to come to your home, you simply blow-dry your hair using a diffuser. These tools come in multiple different shapes, sizes, and types. Many feel like they are wasted money and that you could never get the curls you were hoping for. However, if you know how to use a hair diffuser you’ll be pleasantly surprised at how they create gorgeous curls and volume.

The key to using a hair diffuser is to hold it as close to the scalp as possible. Then use the blow-dryer as you normally would. This creates a lasting effect instead of simply drying your hair like a styrofoam cup. This trick will intensify your blow-out and give your locks more body and bounce.

What makes a hair diffuser good?

A hair diffuser is an essential tool for anyone who wants to tame their hair while adding volume. The design of a diffuser is essentially a series of pores and spaces that it then distributes the hot air from your blow dryer over in a sort of swirling motion. You might think that scattering hot air directly on your hair would be damaging, but it actually does the opposite. The hot air is circulated on your hair along with the cool air from the room, so your hair ends up more moisturized- and less killed!

A good hair diffuser will be made of a light but strong material so you can squeeze the air through its small spaces but it will not tear or rip when you use it. The more efficient the air flow the better your hair dryer will work, which is why you will often find materials like nylon and silicone in a good diffuser.

Is the Deva diffuser worth it?

We all want beautiful natural curls and waves. Diffusers are the great way to achieve them. The Deva is a well-reviewed hair diffuser, but does it live up to the hype?

Conclusion

Although there are many different hair diffusers to choose from, we believe these are the best because they are created by a brand that has been in business for over 100 years. They offer good designs and different sizes to accommodate singles and families with multiple users. They are also easy to use, both in design and function, and compact enough to travel with or even store. They don’t leave your hair with the crunchy texture we dislike about some of the bigger diffusers, and they are adjustable to different heights to create volume or lift. The nozzles swivel to help reach every section of hair to avoid missed spots.
