What is the function of a clipper guard?

The function of a clipper guard is to control the length of hair being cut. Clipper guards are attachments that fit onto the blades of hair clippers, allowing barbers to achieve a variety of hair lengths with precision. Each guard is labeled with a specific length measurement, enabling the barber to select the desired guard for the client’s haircut. This helps ensure uniformity in the haircut and enables the barber to execute different styles effectively while avoiding cutting the hair too short unintentionally. The other options do not accurately represent the primary purpose of a clipper guard, which is specifically aimed at length control.
