When cutting below the fingers along the perimeter, how thick should the back sections be parted?

When cutting below the fingers along the perimeter, the thickness of the back sections should ideally be parted at 1/4 to 1/2 inch. This thickness allows for adequate control and precision during the haircut, ensuring that each section can be managed easily.

Parting the hair in this range helps to create a clean and even cut, as well as to minimize the risk of cutting too much hair at once, which can lead to uneven layers or an unintended shape.

Using this specific sectioning size also complements the technique of cutting below the fingers, as it enables the barber to maintain a steady hand and to see the line of the cut more clearly. The choice of parting thickness can significantly impact the final look of the haircut, especially with perimeter work where precision is key.
