11 Best Diffusers for Curly Hair (2025), Tested and Reviewed

- Tepenar Bonnet Hood Dryer Attachment
If you hate holding up a hair dryer to dry your curls and wish you had a salon-style hair dryer to do it for you, here's the closest option to use at home—and costs less than $20. This bonnet hood, like the DevaFuser below, is a universal attachment, with the hose fitting most standard hair dryers with a Velcro strap to secure it. Once the hose is on, the hood goes on your head and around your hair. There're two layers in the hood, so the air fills the first layers and then is dispersed through the ventilation holes to reach the second layer where your head and hair will be.
There're several similar options on Amazon, but former WIRED reviewer Medea Giordano likes this one since it had enough room for her long, curly hair to lay naturally rather than get scrunched up, and it dries her hair in a span of 30 minutes. It usually takes her over an hour to dry her hair, and allows it to dry all at once rather than having to move the diffuser around to get each part of her head. —Nena Farrell
Settings Uses dryer settings What's included Bonnet hood Warranty None Even at its highest heat setting, the Pattern Blow Dryer doesn't get as hot as some other hair dryers, which helps to minimize damage. It has foolproof switches—choose between three heat levels and two airflow levels—plus an ion customization button that you can activate for smoothness or deactivate for more volume. There's also a cold shot button that's useful when you're finishing up your drying routine. I like that the switches aren't difficult to use. This comes with four attachments—a diffuser, a wide-tooth comb, a brush, and a concentrator nozzle. The attachments lock in place and can be oriented vertically or horizontally, which I appreciate since it allows me to target specific areas of my hair. (For example, I use the concentrator nozzle to give my roots volume without worrying about drying the rest of my hair straight.)
The diffuser is huge and easy to maneuver, especially since the lightweight body of the dryer stays cool to the touch, and it's easy to hold by the top or base depending on how you like to style. The diffuser's long, ventilated prongs dried my hair efficiently while giving my curls a ton of volume and definition. Most important, I didn't get tired and my biceps didn't give out, even while diffusing with my head upside down or hover-diffusing. This setup might take a bit longer than other, hotter dryers, but I think the trade-off is worth it. —Louryn Strampe
