If you have curly or wavy hair, the diffuser is the most important part of your dryer. It spreads the airflow so curls dry in shape instead of being blown apart. A deep bowl with long prongs also lifts the roots.
Our pick: the Dyson Supersonic Nural, which includes a wide diffuser and lowers heat automatically near the scalp. For value, the Wavytalk Blown Away is built for curls and has about 26,000 Amazon ratings at the time of writing.

FAQs
Is a diffuser good for wavy hair?
Yes. It helps waves dry with more definition and less frizz.
Can I add a diffuser to any dryer?
Universal diffusers exist, but fit varies. A dryer with its own diffuser is easier.
What heat should I use when diffusing?
Low or medium, with low speed.
Does diffusing take longer?
Usually, yes. Air-drying partway first can shorten it.
