What should be applied to the hair before cutting to ensure precision?

Applying a sparing amount of water to the hair before cutting is beneficial for achieving precision in haircutting. When hair is slightly dampened, it becomes easier to manage and manipulate, allowing for more accurate cutting. Wet hair tends to clump together, providing a clear view of the hair’s density and structure, which aids the barber in making precise cuts. This is particularly important when creating specific styles that require clean lines and uniform length.

Using a generous amount of conditioner, hair gel, or leave-in conditioner can make the hair overly slippery or weighted down, potentially leading to uneven cuts or difficulties in handling the hair during the cutting process. These products may interfere with the barber's ability to see the natural fall and flow of the hair, which can compromise the skill required for cutting accurately. Therefore, a sparing amount of water is the ideal preparation for maintaining control over the hair while cutting.
