HAI Ultra Stik 1" Ceramic Digital Flat Iron Hair Straightener is a wonderful styling choice for anyone looking for the latest technology in a heat styling appliance. This versatile styling tool produces far infrared heat to ionically charge the hair and close the cuticle, sealing in natural moisture and oil, creating smooth styles with unbeatable shine. The automatic temperature control is preset at 170 degrees F and adjusts up to 390 degrees F in just seconds. We suggest the lowest setting (from 60 degrees) for fragile, fine hair, up to the highest setting for thick, coarse hard-to-straighten hair. It’s easy to see the temperature, it’s got the digital temperature control and display right on the ergonomic handle. Sweet!
