CHI Haircare is expanding its popular CHI Vibes line with the addition of a new tool: The CHI Vibes “On the Edge” Hairstyling Iron. This 1-inch iron features ceramic plates that curve to the outer sides of the iron, which ensure styling closer to the scalp to tame hard-to-reach roots and edges. The preset temperature dial includes 300F, 340F, 380F and 410F, and features a one-hour auto shutoff.
