"Diffusing" in blow-drying techniques specifically refers to gently drying hair while enhancing curls or waves without creating frizz. This technique typically involves using a diffuser attachment on a blow dryer, which disperses the airflow over a larger area. This helps to maintain the natural shape of curls and waves, allowing them to dry in a way that emphasizes their texture without overwhelming them with direct, forceful heat.

Using a diffuser is particularly beneficial for those with textured hair, as it minimizes disruption to the hair cuticle, thereby reducing frizz and promoting a smoother finish. This method contrasts with approaches that apply high heat or direct airflow, which can lead to unwanted frizz and damage, making the preservation of curls more challenging.
