Consult the enclosed user guide prior to use. Begin with dry, detangled hair. Divide hair at the temples and secure the top half out of the way. Then divide the bottom half into 1-2'' sections to begin styling. Secure the ends of a section underneath the clamp and roll upwards, wrapping the hair evenly around the barrel. Hold for a few seconds, then release the clamp. For loose, wavy curls, tug slightly on the ends before allowing it to cool.
Precautions: Use a heat resistant glove when styling to protect against accidental burns in case your hand comes in contact with the heated barrel.
