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

Using a cape during a haircut primarily serves to keep the client clean and comfortable by collecting hair clippings. When hair is cut, it tends to fall onto the client's clothing and skin, which can lead to discomfort and an unkempt appearance after the haircut is finished. The cape acts as a barrier, capturing these hair clippings and preventing them from settling on the client, thereby enhancing the overall experience of the service. It also helps maintain a tidy workspace, making it easier for the barber to manage the area.

The other options do not accurately represent the primary function of a cape. While tools and hair products may play roles in the barbering process, the cape's main focus is on client comfort and cleanliness, highlighting its essential role in the haircutting environment.
