What is the primary purpose of a neck strip?

The primary purpose of a neck strip is to prevent hair from falling on the client's skin. When a barber cuts hair, loose strands can easily fall onto the client's neck and clothing, causing discomfort or irritation. The neck strip acts as a barrier, catching the hair and keeping it from coming into direct contact with the skin. This not only enhances the client's comfort during the haircut but also promotes cleanliness and allows for a more enjoyable experience.

The other options presented do not align with the main function of a neck strip. While a neck strip may inadvertently contribute to fashion by adding a professional touch, that is not its intended purpose. Similarly, marking the beginning of a haircut is not relevant to what a neck strip does; it serves a practical function rather than a symbolic one. As for securing a cape, that task is typically performed using other methods, such as clips or ties, and is separate from the role of the neck strip.
