Define "true length" in the context of hair cutting.

The term "true length" refers to the actual length of hair that is visually apparent after it has been cut. This is important in hair cutting because it takes into account how the hair falls and appears in its natural state, rather than just a measurement of the length before cutting. Understanding true length helps barbers and stylists in achieving the desired look, as hair can appear differently based on its texture, movement, and how it has been styled or layered. This concept is crucial for ensuring that clients receive a haircut that meets their expectations not just in terms of length but also in terms of appearance and style.
