The Revlon Pro Collection Salon Straight Copper Smooth 1 1/2" XL flat iron helps you quickly and gently glide your way to long-lasting, smooth, straight, shiny styles with less frizz. Featuring an optional slide-on smoothing attachment with snag-free bristles, hair is distributed evenly across the plate for better control, glide and one-pass styling. The technology's even heat distribution delivers 24-hour frizz control, and an exclusive extra-large plate delivers twice as much styling power for expanded coverage and faster results. Thirty variable digital LCD heat settings (from 180° (F) to 455° (F)) of professional high heat provide precise styling control and flexibility for all hair types. Other professional features include a 60-minute auto shut-off, 10-second heat-up, color fade control, Smart Heat Memory System that automatically recalls the last temperature as your preferred heat setting, and a plate-locking switch for easy storage. Based on testing by an independent third-party lab. When used at a setting of 400° (F) or below.
