What is the main benefit of using a diffuser attachment on a blow dryer?

Using a diffuser attachment on a blow dryer is primarily beneficial for scrunching hair or manipulating curly or wavy hair. The design of the diffuser allows for hot air to be dispersed gently, reducing the intensity of the airflow that directly hits the hair. This helps to maintain the natural pattern of curls and waves while minimizing frizz.

When using a diffuser, stylists can scrunch the hair or add lift at the roots, enhancing the natural texture without disrupting the curl definition. This technique is essential for achieving a defined, bouncy look in curly hair types that might otherwise lose their shape with direct heat from a standard blow dryer.

While adding volume to fine hair is a potential benefit of using a diffuser, its primary purpose is focused on curly and wavy hair. Straightening hair or drying it quickly are not advantages typically associated with the use of a diffuser, as those tasks are better suited to other tools or attachments.
