The purpose of a diffuser in hairstyling is to distribute air evenly and create soft curls or waves without frizz. When using a diffuser, it attaches to a blow dryer and helps to spread the airflow over a larger area of hair. This gentle, more diffused airflow prevents the vigorous blowing action that can lead to frizz, allowing the natural curl pattern to form beautifully. As a result, it enhances the texture and definition of curls or waves while minimizing heat damage, providing a softer and more polished look. This technique is particularly beneficial for individuals with wavy or curly hair, as it supports their natural texture rather than disrupting it.
