A hair curler, also known as a curling iron or curling wand, is a hair styling device designed to create curls, waves, or volume in the hair. It typically uses heat to temporarily reshape hair strands by wrapping sections around a heated barrel. Hair curlers come in various sizes and styles, including clamp irons, wands without clamps, and automatic curlers. There are also non-heated options like foam or Velcro rollers for more gentle styling. Ideal for both casual and formal looks, hair curlers are a versatile tool for achieving a wide range of textured hairstyles.
