If you have curly hair, there’s an incredibly high chance your curls have been kissed by a diffuser before. And if not, well, please enjoy this complimentary hug, because your poor hair has clearly been wronged in the past. Listen, I'm not saying that every single wave, curl, and coil type absolutely needs to be diffused for the absolute best finish, but if you've been feeling meh about your hair recently, or you just wanna see how far you can really take your texture, I highly recommend using a diffuser. Which brings us to...

What does a hair diffuser do?

As a refresher, hair diffusers are bowl-shaped attachments that disperse the flow of air from your blow dryer, helping to dry your curls more evenly and gently while preventing frizz, encouraging definition, and creating major volume. So rather than your hair blowing wildly into the wind (which = tangles/flyaways/nightmares), a diffuser cups and nestles your hair in one place while it dries.

What is the best hair diffuser?

K, so even though the idea of all diffusers is the same—i.e., to diffuse air—not all diffusers are created equal. Different hair types can get better results from different bowl shapes and prong lengths (ex: cropped, 4a hair has different needs than long, super-thick 2c wavy hair). So to help you parse through the zillions of options on the market, I handpicked the 15 best diffusers for wavy, curly, and coily hair, below. But lemme first give you just a lil bb sneak peak of my top favs:
