Never heard of a hair dryer diffuser before? You’ve come to the right place. We’re breaking down everything you need to know about hair dryer diffusers, including how to diffuse hair using one. We’re also featuring 12 of the best hair diffusers out there.

What is a hair diffuser?

A hair dryer diffuser is a tool that’s attached to your blow dryer that helps evenly disperse air over a larger area of your hair. It’s round and covered with “spikes” that help keep your curls separated while creating more lift at the root.

What does a hair diffuser do to your hair?

When you use a blow dryer with a regular attachment, you get a strong, steady stream of air. A diffuser attachment eliminates that concentrated stream of air and instead disperses it, which in turn prevents disturbing the natural curl pattern. The result: You can dry your waves and ringlets with lightning speed and enjoy seeing less frizz, more definition, and improved volume.

Who should use a hair diffuser?

Hair diffusers can technically be used by anyone, but they’re particularly beneficial for those with curly hair or even wavy hair. Their ability to eliminate frizz and boost body makes hair dryer diffusers a must-have in hairstyling routines.

How do you use a hair diffuser?

As far as how to diffuse curly hair or wavy hair, there are a few different methods you can try when using a hair diffuser attachment tool.

One of the most common techniques is to place your mid-shaft to ends on the diffuser and use it to scrunch your hair up as the blow dryer dries. This helps your curls maintain their natural shape and disturbs them less while drying. If you're looking for a style with a little extra volume, flip your head over and diffuse your locks upside down to help create volume right at your roots.

If you’re worried about concentrating that much heat, hold the diffuser six inches away from your mane and slowly pass the blow dryer down the length of your curls. It’s a similar technique to traditional blow drying, but the air is dispersed more evenly so it’s less severe. Continue this process until your hair is completely dry. Since this can take a while, you could let your hair air dry a bit, then go in with the blow dryer.

Products To Use When Diffusing Your Hair

Whether you opt for a spray formula like Biolage Thermal Active Heat Protectant Spray, or a cream formula like Shu Uemura Art Of Hair’s Netsu Design Blow Dry Cream, pick a heat protectant product you will enjoy using every time you heat style your hair.

You can pair your heat protectant with a curl-defining cream, such as Mizani True Textures Curl Enhancing Lotion which helps create soft and touchable curls instead of stiff or sticky ringlets.

After you’ve finished diffusing your hair, we recommend going in with some styling products to perfect your mane. For example, Mizani Thermasmooth Smoothguard Serum helps further eliminate frizz for a beautiful, sleek finish. At the same time, its cationic polymers help lock in shine and keep humidity out while ceramides penetrate the shaft to reinforce strength. You can further smooth flyaways with a product such as Mizani Edge Trimming Hair Gel, which helps keep the most defiant strands in place.
