DevaCurl Devafuser

Spot number four has to go to the one and only DevaCurl– it is the best helping hand your curls could ask for. The Devafuser helps dry curls with unbelievable shape, definition, and volume. 

This 360-degree airflow surrounds curls and allows you to get right to the root, which is the key to the volume and where it takes the longest to dry, for speedier drying time than any there diffuser. 

But that’s not all…

The ceramic inner core helps preserve moisture which is key to reducing frizz and enhancing shine. With curly hair, we want to preserve as much moisture as possible to keep the ends of our curls healthy, defined, and frizz-free.

However, my only pet peeve is that DevaCurl claims this diffuser will fit any blow dryer, but many customers found that this wasn’t the case. Be sure to check measurements before purchasing!

Other than that, this dryer works wonders for frizz and really helps define lifeless curls. 

Pros
  • 360-degree airflow surrounds curls for shape, definition, and volume
  • Adds volume to lifeless curls 
  • Ceramic core helps preserve moisture and tame frizz

Cons
  • Doesn’t seem to fit ‘every’ hairdryer

The Best Diffusers For Curly Hair-- A Buying Guide

If you’ve never tried a diffuser when drying your curly locks, all I can say is you’re missing out. There are lots of different brilliant ways to dry your curls, whether it’s through plopping or leaving it to naturally dry.

But sometimes, we just don’t have enough time to wait hours for our curls to dry, and going to bed with wet hair is a no-no. Investing in a hair diffuser for your curls is definitely worth it; they’re super easy to use and will leave your curls looking defined.

Diffusers for curly hair work differently from just blowdrying your hair with a hairdryer. Instead of directing heat to one hair to dry strands, they evenly distribute heat in a 360 direction to wrap around curls and gently dry curls.

Stay tuned for everything you need to know when buying a diffuser, along with techniques and top tips and tricks. Want to know the best ways to dry curly hair? Check out my full guide here.

Let’s jump into all the nitty-gritty details, friends!

What Is A Hair Diffuser?

A diffuser is an attachment for your blow dryer that disperses air evenly to reduce frizz and keep it from disrupting the natural curl pattern. It helps dry your curls more evenly and gently without causing frizz.

Using a diffuser will help define curls and add major volume; instead of your hair blowing around wildly and causing damage from the heat of a regular blow dryer, a diffuser cups and nestles hair in one place.

It comes in a bowl-like shape with prongs that are designed to cradle hair. These prongs can also help lift the root to add any volume and lift the hair from the scalp. You can even use this while your head is upside down for any extra volume.

Your hairdryer may not come with a diffuser, so you may need to buy the attachment separately, but they’re universal and easy to get hold of. Just be sure to buy the right size for your hairdryer.

How To Diffuse Curly Hair:

If you have long, thick curly locks, there’s always going to be a struggle on wash day, plus drying your curls naturally can take hours and a hell of a lot of patience. Using a diffuser can cut time in half, but how exactly do you diffuse curly hair.

You may need to purchase a diffuser separately, but it is an attachment that is definitely worth the investment.

Step One: Wash your hair:

Fast forward to wash day; your hair is needing some TLC and a good massage to help get rid of all the dirt and grime you’ve collected from the week. Remember to use either a sulfate-free shampoo or cleansing conditioner. 

We all know how to wash our curls by now, right? If you’re still a newbie to the curly girl method and not sure where to begin, don’t worry, I’ve broken it all down in my full guide to washing curly hair here

Once you’ve washed and conditioned your hair, grab the comb and comb through your curls with either the conditioner or after rinsing and applying your trusty leave-in conditioner.

Be patient for this step; start at the bottom and work your way up. Tugging and snagging your curls while combing or brushing can cause breakage or damage the curl pattern– since hair is most fragile while wet.

Step Two: Apply styling products:

Got a comb through what feels like a bird’s nest of curls? Brilliant, now it’s time to apply your curl-defining styling products. Don’t forget your heat protectant too, while you may only be using low heat; any direct heat can damage curls without a heat protectant.

Whether you’re using gels, creams, or mousses, here’s a pro tip: I like to work in sections to ensure every curl is defined. Grab yourself a water spray and work through each layer and each section.

Spray down each section with the water spray until it is sopping wet, apply your styling products to that section and then use your styling brush and twirl it through that curl until it looks defined. Then scrunch until you’re happy with the shape. 

This really helps curls defined and adds even more volume when diffusing. 

Step Three: Diffuse

Don’t worry; I’m going into the details. You can use a few different techniques to diffuse your hair; try a couple out and see what works for you.

You can either hold the blow dryer at a 90º angle and place the diffuser at the roots of one section, starting at the nape of the neck and gently holding the eyes away from the diffuser, moving a circular motion and lifting the roots.

Another brilliant way to add volume is to flip your head upside down and place the diffuser at the roots of your hair, using the diffuser’s fingers to lift the root in a circular motion.

Then once the root has a bit of volume, you can scrunch up the mid-shaft to hold and dry; you want the roots and mid-shaft to be completely dry to lock in volume.

Remember to use a low-medium airspeed and low-medium heat, this may take longer, but it will prevent heat damage and frizz. You should also only dry your hair to 80-90%; then air dry the rest. Do the ends last or not at all to keep curls defined.

Diffusing your curls is brilliant for a night out or if you’re quite strapped for time.

Frequently Asked Questions:

What does a hair diffuser do?

So you’ve probably heard the word diffuser being thrown around in the Curly Girl Method community, but what does it actually do, and is it worth using on curly hair?

Absolutely! Investing in a diffuser is definitely worth it if you’ve got curly hair. Unlike regular hair dryer attachments, a diffuser attaches to the end of your hair dryer and evenly distributes airflow around each curl.

It cradles each curl in a bowl-like shape, and the prongs help lift the curls from the root for boosting volume and defining curls. Plus, since it gently dries curls evenly, it prevents heat damage, frizz and helps maintain the natural curl shape.

Check out my full guide for more info here.

Can you use a diffuser on straight hair?

If you have straight hair and want it to look slightly wavy, then absolutely, you can still use a hair dryer diffuser. You will love the natural waves a diffuser can create for straight hair.

Once you’ve washed your hair like normal, you can apply mousse; this helps make straight hair wavy. Then grab the diffuser and use the fingers to massage the roots to the ends. You can use a similar scrunching motion to what curly girls would do.

Once you’re happy with the waves, you can then apply a good amount of hairspray to hold in the curls.

Do you brush your hair before using a diffuser?

Before you pick up the diffuser, you should style your curl beforehand. I like to use a Denman Brush and work in sections when applying my styling products. I spray down each section, apply my styling gel, and use my Denman brush to style. 

This doesn’t mean you have to brush your curls before using a diffuser; you should only brush if you’re using a styling brush to define your curls. Just make sure you detangle your hair while wet and not brush once your curls are dry; this will cause frizz. 

Summary

So there you have it; whether you’ve used a diffuser or not in the past, they can really work wonders for your curls. If you have thick curly hair that takes hours to dry, investing in a diffuser is a must. 

It is all trial and error for our curls; sometimes, products will work, whereas others won’t. The same goes for the technique and tools you use; it’s all about working out what works for your curl type. 

Choose any of the diffusers I have selected for you today; thousands of curly girls love and trust these products to dry your hair– but make sure it fits your hair dryer before you purchase!

Happy diffusing, ladies!
