Flexible rods for hair are styling tools used to create beachy waves or voluminous curls on medium-to-long hair. The rods, typically made of a bendable material like plastic or foam, are inserted into damp hair and removed after a period of time to reveal the desired effect.
Flexible rods offer a multitude of benefits, including their ability to create heatless curls, which helps preserve hair health. They were first introduced in the 1980s but have recently gained popularity as a gentler alternative to thermal styling tools.
