When cutting hair, which part of the head should typically be cut first?

Starting with the back of the head when cutting hair is a standard practice in barbering for several reasons. Cutting the back first allows the barber to establish the foundational length and shape of the hairstyle without interference from the hair on the sides or top. This approach provides a clean starting point that helps maintain symmetry and balance throughout the haircut.

Additionally, cutting the back first allows for better visibility and control when transitioning to the sides and top. By beginning at the back, the barber can more effectively gauge how the haircut will flow and ensure that all areas blend seamlessly. Furthermore, some haircuts require the back to be cut shorter than the top or sides, making it logical to start at the back to build up to the desired style.

This technique is widely recognized and taught in barbering practice, as it integrates well with various haircut styles and ensures a polished end result.
