The CHI's ergonomic design allows the user to flip hair up or curl it under with a twist of the wrist. The CHI is ideal for straightening and smoothing the hair while the ceramic plates seal in natural moisture. It's great to use prior to a Dry Haircut. The ceramic coated paddles help prevent scorching hair color and helps reduce styling product build-up. Featuring an extra long swivel cord to prevent tangling, the CHI has a concealed on-off switch inside the handle to prevent accidentally turning the unit off when in use. The heat paddles are recessed from the edges to prevent skin burns.
