process of flattening curly or wavy hair for smoothness

Hair straightening is a hair styling technique used to flatten and straighten curly or wavy hair, giving it a smooth, sleek appearance. This can be achieved through various methods, including chemical treatments like relaxers or keratin treatments, and mechanical means such as flat irons or blow-drying with a round brush. The effects can be temporary or permanent, depending on the method used.
