What is the technique used to ensure precision in hair cutting by parting subsections opposite from the elevation or direction where hair was cut?

The technique that ensures precision in hair cutting by parting subsections opposite from the elevation or direction where hair was cut is cross-checking. This method is employed after the initial cut has been made. By examining and cutting the hair in the opposite direction, the barber can effectively verify the accuracy of the previous sections and make necessary adjustments. It helps to identify any inconsistencies or unevenness in the cut, ensuring that the overall style is balanced and precise.

This is crucial because it allows the barber to catch mistakes that may not be apparent when viewing the hair from the original direction of cutting. Cross-checking is an essential skill that enhances the quality of the haircut by promoting thoroughness and attention to detail.
