When should a barber use a neck strip?

A neck strip is used primarily to protect the client's neck from hair clippings during haircuts. This strip creates a barrier between the hair being cut and the skin, ensuring that loose hairs do not irritate or stick to the skin, which can be uncomfortable for the client. Additionally, using a neck strip helps in maintaining hygiene and cleanliness by preventing hair from spilling onto the client’s clothing.

Option related to cutting long hair and the application of chemical treatments, while relevant in a barbering context, do not specifically address the main purpose of the neck strip. Drying hair does not necessitate the use of a neck strip either, as the primary focus during that process is different. Therefore, the use of a neck strip emphasizes the importance of client comfort and cleanliness, making it the appropriate choice in this scenario.
