Using the wrong guard size is a common mistake when using clippers because the guard size determines the length of the hair that will be left after cutting. Each guard size corresponds to a specific length of hair, and selecting an inappropriate guard can lead to unsatisfactory results, such as cutting hair much shorter or longer than intended. It's essential for barbers to be familiar with the different guard sizes and how they affect the cutting process to achieve the desired look for their clients.

In contrast, keeping the clipper blade clean, cutting wet hair, and maintaining a steady hand are generally good practices. Clean blades ensure effective cutting and reduce the risk of pulling or snagging hair. While cutting wet hair can alter the way hair behaves, many barbers choose to do this as part of specific styles or techniques. A steady hand is crucial for precise cutting and blending, ensuring the haircut turns out as intended. Therefore, the selection of the proper guard size is key to achieving the correct haircut and avoiding common pitfalls in barbering.
