What is the primary purpose of a cape during a haircut?

The primary purpose of a cape during a haircut is to protect the client's clothing. Capes are designed to cover the client's garments, preventing hair clippings, styling products, and water from adhering to their clothes. This protective function is crucial in maintaining the client's comfort and ensuring that they leave the salon or barbershop with clean attire. While other options may describe aspects associated with a barber's practice, such as enhancing professionalism or offering comfort, the essential role of the cape directly relates to safeguarding the client's clothing during the cutting process.
