A permanent wave refers to a chemical process designed to alter the natural structure of hair, allowing it to curl or wave for an extended period of time. This method involves the use of specific chemicals that break down the hair's natural protein bonds, enabling stylists to reshape the hair into curls or waves that hold their form.

The significance of a permanent wave lies in its ability to provide long-lasting texture and volume to hairstyles, offering clients the chance to enjoy curls or waves without the daily maintenance that traditional styling would require. This process can vary in use and application, resulting in different types of curls or waves based on the desired outcome and the tools employed during the treatment.

In contrast, the other options refer to different hair manipulation techniques. Straightening hair focuses on creating a sleek look, which is not the intent of a permanent wave. Hair extensions involve the addition of extra hair for length or volume, rather than altering hair texture. Styling techniques that utilize heat may also achieve temporary curls or waves, but do not provide the durable results that a permanent wave offers.
