When should a barber use a guard on clippers?

Using a guard on clippers is essential when the goal is to achieve an even cut length. Guards come in various sizes, with each corresponding to a specific length of hair they will leave behind after cutting. When clients request a uniform cut, applying the appropriate guard ensures that the hair is cut to the same length throughout the entire section. This method helps barbers maintain consistency and precision, which are crucial for a polished and professional finish.

While creating a textured look and trimming around the ears may involve the use of clippers, these tasks often require freehand techniques or attachments that allow for more variation in length. Additionally, fading hair color is unrelated to the use of guards on clippers, as it pertains to dye application rather than cutting hair itself. Therefore, the use of a guard is specifically aligned with the practice of achieving an even cut length.
