Paul Mitchell Curl Round Trip Defining Serum delivers flexible hold and touchable definition for waves and curls without weighing hair down. The lightweight formula blends panthenol and magnesium sulfate to condition and strengthen, while cornstarch-derived styling agents create frizz-free structure. A real time-saver: this serum noticeably reduces drying time, so you can get gorgeous, defined curls faster.

Usage: Apply a small amount to clean, damp hair. Style as desired.
