Hair curling products are tools or substances designed to create defined, long-lasting curls in the hair. A common example is the curling iron, which uses heat to shape and hold the hair in curls.
Curling products have been widely used for centuries to enhance hair texture and volume. They offer the benefit of creating various curl patterns, from soft waves to tight ringlets. One significant historical development was the invention of the electric curling iron in the 1930s, making curling more convenient and accessible.
