What is the purpose of using a neck strip during a haircut?

Using a neck strip during a haircut is primarily intended to keep hair off the client's skin and prevent irritation. When hair is cut, small hairs can fall onto the client's neck and skin, leading to discomfort or itching. The neck strip acts as a barrier between the sharp ends of the hair and the skin, ensuring a more comfortable experience for the client throughout the haircut process.

This practice not only enhances the client's comfort but also helps maintain cleanliness and hygiene during the service. The neck strip allows for easy cleaning up of hair remnants after the haircut, ensuring that the client leaves the salon without stray hairs irritating their skin. While the other options mention different functions, none align as closely with the primary purpose of keeping the client comfortable and preventing irritation.
