When performing a haircut, what should be done to achieve a clean line at the perimeter?

To achieve a clean line at the perimeter when performing a haircut, utilizing a guide is essential. A guide serves as a reference point to ensure uniformity and precision in the cut, allowing the stylist to establish a sharp outline along the hair's edges. This technique is particularly important for outlining styles such as blunt cuts, where the perimeter needs to appear crisp and well-defined.

Incorporating a guide aids in maintaining consistency throughout the haircut, making it easier to achieve the desired length and shape. A clear focus on the guide allows for better control and a more polished finish, which is critical in professional hairstyling.

Other methods, such as using dull scissors, won’t produce a clean cut and can lead to frayed ends. Texturizing the ends can soften the look but does not contribute to achieving a defined perimeter. Dry cutting may offer some benefits in certain styles but does not ensure the accuracy provided by a guiding method, especially when creating clean, straight lines in the haircut.
