For those not in the know, a diffuser attachment is a round plastic extension that slides onto the nozzle of your blow dryer. Its main function is to disperse your hairdryer’s airstream over a wider area in a more controlled way, meaning it can help to keep curls in their natural shape and prevent frizz when blow-drying.

If you have curly hair, a diffuser is an absolute must-have for your beauty kit. Not only does it create major volume, but it also helps to define your curls and encourages definition, all while protecting your hair from heat damage.

Curly hair experts have been raving about the power of diffusing for quite some time, and it’s no wonder: The process is gentle on curls while simultaneously encouraging bounce, volume, definition, and moisture retention. It can also help reduce frizz and flyaways, while speeding up drying time.

To get the most out of your diffuser, it’s best to start with freshly washed, detangled locks and apply any styling products you may need (think: a volumizer and heat protectant). “Use a brush for curly hair while wet and blot your curls until they are damp but not soaking wet,” recommends beauty expert Nika Collins.

Next, either plop your curls into a classic diffuser cup or opt for the hand diffuser option—which is what we’re showing you in this article. It has different finger-like prongs that distribute heat evenly and allow for a customizable look that sets your curls naturally. diffuser attachments
