A hair straightener, or flat iron, is an electronic appliance used to make curls or waves in hair appear straighter. It is a popular styling tool, especially among people with naturally curly or wavy hair, who may want to change the texture of their hair for a special occasion or as a part of their regular hair care routine.
Hair straightening has been around for centuries, with historical evidence suggesting that ancient Egyptians used hot rods to straighten their hair. Modern hair straighteners were invented in the early 1900s and have since become more advanced, with features such as adjustable heat settings, ceramic plates, and ionic technology that helps to reduce frizz and damage.
