How can a barber ensure a precise haircut?

Using a mirror to check for symmetry is essential for ensuring a precise haircut. The mirror provides a reflective surface that allows the barber to visually assess the evenness and balance of the haircut from various angles. This step is crucial as it helps identify any discrepancies in length or shape that may not be immediately visible from the barber's viewpoint. By regularly checking the haircut in the mirror while making adjustments, a barber can refine their work and achieve a more polished and professional finish.

Combining this technique with other skills and tools can enhance the overall quality of the haircut. Relying solely on experience may lead to oversights, as even seasoned barbers can benefit from the visual confirmation that a mirror provides. Likewise, using only a comb could restrict the barber's ability to see the full picture of the client’s head and hair from multiple angles, while cutting quickly might compromise precision and the final result. Thus, the use of a mirror stands out as a fundamental practice for achieving symmetry and accuracy in haircuts.
