Name one benefit of using a diffuser with a hairdryer.

Using a diffuser with a hairdryer is particularly beneficial for those with curly or wavy hair because it helps distribute the heat more evenly and gently. This technique allows for the formation of soft waves, enhancing the texture of curly hair while preventing frizz. The diffuser's design—often featuring prongs or openings—ensures that the airflow is diffused rather than concentrated, minimizing disturbance to the natural curl pattern. As a result, hair dries in a way that maintains its shape and bounce, leading to a more polished and defined look without the frizz that can often accompany direct heat from a traditional hairdryer.

The other potential benefits associated with a hairdryer might not apply to the specific function of a diffuser; for instance, it does not inherently speed up drying time or achieve a straight look, nor does it necessarily add shine to hair in the same way that specific shine-enhancing products might.
