Say hello to volume, bounce and definition.

Members of the curly hair club, this one’s for you. At this point, we know coils, curls and waves deserve special care to keep them looking fresh and bouncy. Of all the hair styling tools in your kit (which includes hair oil and a hair mask), finding the best hair diffuser is essential.

Hair diffusers are bowl-shaped attachments that snap to your dryer to help diffuse the flow of air to your curls to encourage clumping and definition. With one of the top diffusers, you can speed up your drying time, leaving your curls super voluminous and defined, with less frizz and flyaways.

What to look for in the best hair diffusers

Has your blow-dryer ever left you with frizzy, dried-out hair? We get it. “A diffuser gently disperses airflow from your hairdryer, avoiding direct force or pressure preserving the hair’s integrity and shape,” explains Aliza Esmail, owner of Toronto’s Salon August. “Its purpose is to promote natural drying without disrupting the curl pattern.”

While diffusers work wonders for curly and wavy hair types, they are versatile enough for any hair type. “They accelerate drying without the need for forced air or concentration, ensuring a natural dry effect and minimizing heat damage,” says Esmail.

When it comes to finding the best one, she recommends a diffuser with longer prongs. “Diffusers with extended prongs promote airflow to the scalp, giving root lift for voluminous curls without compromising their structure and minimizing frizz. Certain diffusers optimize air passage through the prongs, expediting the drying process.”

After diffusing your mane, Esmail notes hair should feel bouncy, defined and soft. “[Through using a diffuser] you can both promote volume and fullness as well as contain natural textures.”
