T3 Featherweight 3i Hair Dryer and Diffuser Discover shiny, healthy-looking results in less time. Powered by T3 IonAir Technology, the T3 Featherweight 3i hair dryer infuses negative ions into a wide and gentle airstream to smooth the hair cuticle and speed up drying while remaining gentle on hair. Three heat settings, two speed settings, and a lock-in cool shot offer total styling customization for all hair types and textures. A lightweight and quiet design creates a comfortable and pleasant styling experience. The T3 Featherweight 3i includes three attachments to deliver versatile styling for all hair types: Use the Drying Concentrator to rough-dry hair with a wide, ion-rich airflow; use the Styling Concentrator to smooth and style, one section at a time; and use the SoftTouch 3 Diffuser to lift and define curls, waves, coils and layered styles.
