Hot Tools Tourmaline Turbo Ionic Dryer features a pro-moisture system with tourmaline and ionic technologies that does more than just dry hair... it transforms airflow into a hydrating spa treatment!Tourmaline converts heat into penetrating far-infrared energy, drying the cortex (interior) without over-drying the cuticle (exterior). Also helps cleanse hair of odors and impurities. Direct Ion Technology leaves the cuticle silky, shiny, softer, and less frizzy by breaking water into smaller, easier-to-evaporate droplets. Quiet operation - powerful performance.Professional Features:
