Curling wands are hair styling tools used to create curls and waves in the hair. They come in various sizes and shapes, and are typically made with a ceramic or tourmaline barrel that heats up to create the curls. Curling wands can be used on all hair types, but the size of the barrel will determine the size and tightness of the curls. Smaller barrels are ideal for tighter curls, while larger barrels are better for looser waves.
