The Andis Colorwaves Hairdryer is infused with Tourmaline. Crushed from precious stones, Tourmaline crystals emit negative ions that quickly seal the cuticle layer and eliminate frizz for smoother, silkier hair in 60% less time. Nano-ceramic, with its ultra smooth finish, minimizes friction and delivers far-infrared heat that dries the hair from the inside out for deep, long lasting styles.
