Let us guess: When you dry your hair (with direct heat on your scalp), you get frizzy curls and breakage. And when you opt to air-dry instead, it takes hours for your hair to be completely dry. It’s a major hair dilemma for waves, curls and coils right? But it’s one that can easily be solved with a good ole diffuser. This handy attachment is a curly gal’s secret weapon. Not only do they dry hair, but they also define curls and reduce frizz. Still not sure what the heck a diffuser is (or the point)? Here's everything you need to know and why you should get your hands on one.

What is a hair diffuser?

A hair diffuser is an attachment (or nozzle) that can snap/slide onto your blow dryer. Instead of heat pouring out directly onto your hair, the diffuser disperses the air around the curls to improve definition, reduce frizz and create volume. Without a diffuser, curly hair can resort to more tangles, breakage and overall a loss of its shape. But how do we know if it's a diffuser? The nozzles are usually plastic, bowl-shaped and feature prongs inside the attachment. However, some can look like "fingers" (like the DevaCurl DeFuser) or a sock (like the Hot Sock Diffuser). Finding the right diffuser for you all depends on your curl type and/or texture.

The best hair diffuser for your curl hair

As mentioned before, the shape, size and/or prong lengths can determine what diffuser work for your waves, curls or coils. If you have thick and/or long hair, you want to pick a diffuser with a large head and a lot of prongs to let the airflow move across your hair (and cut drying time by half). If you have frizzy, fine or short hair, you should reach for a small head (or a sock) diffuser to give you a gentler experience. And if you have coily hair, shape definitely matters when looking for a diffuser, so look for one that’s finger-shaped to get the job done.

But before adding any attachment to your shopping cart, check to see if your hair dryer is compatible with your nozzle of choice. Some diffusers are not universal (even if they have universal in the name). After you find that your attachment is a match with your dryer, you can begin to dry your hair without any issues. Now that you’re up to speed on what a diffuser is and which type might work best for you, here are 16 of the best diffusers for curly hair to consider when upgrading your drying game, according to reviewers:

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.

It disperses heat evenly and I got much better results than my traditional diffuser."

How to use a diffuser on curly hair

Found a diffuser? Perfect! Now, here's a step-by-step tutorial on how to use it on your curls (and if you need a visual check out the helpful video above to get you started).

1. Wash your hair as normal. You’ll get the best results when your hair is clean. Wash and style it as normal, then apply a leave-in conditioner before you start drying your curls. (FYI, make sure to detangle hair beforehand in the shower for defined curls.)

2. Apply a heat-protectant. Whether it's a serum, cream or spray, applying it directly onto the sections before starting the dryer can reduce frizz, breakage or damage. Here are a few of our favorites: CHI ($6); Briogeo ($24); Bumble & Bumble ($28); Olaplex ($28)

3. Add the attachment to the end of your blow-dryer. Once it's snapped (or slid) on, place your dryer on a low to medium setting. Using the dryer on high heat is a big no-no for curly gals. It'll just create more damage in the long run.

4. Flip your head upside down. Not only does this help dry hard-to-reach areas, but it provides more volume. (Tip to avoid neck cramps, try moving your head to the sides and continue to dry too.) You'll want to first hover the diffuser inches away from your curls. You're focusing on the roots without messing up the curl definition. Once it's been a few minutes, begin to move the diffuser closer to the scalp and move it in a circular motion (almost like a mini massage). Only spend 30 seconds or so on each area to avoid frizz.

5. Focus on the ends. After spending time on your root, take a section and cup it into the diffuser. Focus on that section’s ends for about 30 seconds before moving to the other sections.

6. Finally, shake out your curls. If you want even more volume, use your fingers or a hair pick to fluff up the roots.

It’s important to remember that the time it takes for your hair to dry depends on the length, thickness and/or texture of your curls. You should also only dry 80 to 90 percent of your hair, then let it air dry the rest of the way. Of course, a diffuser is meant to dry your hair, but you don't want to over-dry and take away from the products you just applied (aka leave-in, styling cream and heat protectant). Now, the only thing left to do is marvel at your beautiful, frizz-free curls.
