Why is using a comb or pick important during freehand clipper cutting?

Using a comb or pick during freehand clipper cutting is crucial because it helps to remove excess hair and arrange the cut. This technique allows the barber to section the hair effectively, ensuring that the clipper can reach all areas evenly and provide a more uniform result. It also aids in controlling the length and direction of the cut, which is particularly important in freehand techniques where precision is key. By combing or picking through the hair, the barber can maintain a clear line of vision for the cutting process and make adjustments as needed, leading to a more polished and professional appearance.
