Straightening hair without heat is a practice involving methods to alter the shape of curly or wavy hair to achieve a straighter appearance, usually without using heat-styling tools such as flat irons or blow dryers.
This technique has gained popularity due to its potential to reduce hair damage, preserve hair health, and offer versatile styling options. Its origins trace back to traditional hair care practices, such as wrapping wet hair around cylindrical objects and allowing it to air dry.
