2. Diffuser
The Diffuser is perfect for defining curls and waves while minimizing frizz. Attach the diffuser to the hair dryer. Turn on the appliance. Gently cup sections of your hair with the diffuser, lifting towards the scalp. Use a low heat and airflow setting for best results with curls. The intelligent system will optimize settings to enhance your natural texture. Avoid vigorous shaking to maintain curl definition.
