Using the Attachments
- Concentrator Nozzle (Drying): Use this attachment to quickly dry your hair. Direct the airflow from roots to ends.
- Round Brush (Curling & Volumizing): For curls, take a section of damp hair and wrap it around the brush. Hold for a few seconds, then release. For volume, lift hair at the roots and brush outwards.
- Paddle Brush (Straightening & Smoothing): For sleek styles, brush sections of damp hair from roots to ends. The even airflow helps detangle and reduce frizz.
The advanced airflow engineering ensures even heat distribution at a healthier 212°F (100°C), reducing heat stress and preventing breakage.
