Tourmaline Tools by Hot Tools Professional tourmaline portable salon hair dryer with Direct Ion technology and high airflow tourmaline dries hair up to 50% faster. Tourmaline nano particles naturally generate penetrating far-infrared energy, drying the cortex (interior) without over-drying the cuticle (exterior) and resists brittleness and cracking, helping hair maintain its shine and softness. Also helps cleanse hair of odors and impurities. Direct Ion Technology with negatively charged nano ions leaves cuticles silky, shiny, softer and less frizzy by breaking water into smaller easier-to-absorb droplets.
