Frequently Asked Questions (FAQs)

1. What does a diffuser do on a hair dryer?

Put simply, a hairdryer diffuser is a round, plastic attachment that you can slide onto the nozzle of your hairdryer. A diffuser works by spreading the airstream over a wider area in a more controlled way. Diffusers are great for those with curly to wavy hair types as it can help to keep the natural curl pattern.

2. Can you use a diffuser on any hair dryer?

The diffuser can attach to just about any blow dryer! The universal diffuser broadens and helps reduce the speed of the airflow from your blow dryer to help gently dry, define curls, add shine, and reduce frizz in naturally curly hair.

3. Is a diffuser better than a hair dryer?

"The benefits of using a diffuser are faster drying time, and bouncier, fuller, voluminous curls," Emilio says. "Diffusers diffuse the air, aka, they disperse it, which means it prevents the dryer from roughening up the cuticle of the hair. It protects curls from frizz."

4. Is diffuser same as hair dryer?

Hair dryers are used to dry and style the hair, ensuring that the heat keeps the style in the hair. Diffusers are attachments that can disperse the heat from the hair dryer over a bigger area so that hair dries faster and is less frizzy. The diffuser can also be used to style and adds volume and bounce to the hair.
