What is the significance of using water or a spray bottle during a haircut?

Using water or a spray bottle during a haircut is significant for managing hair texture and preventing frizz. When hair is damp, it is typically easier to manipulate, allowing for more precise cutting and styling. Wet hair can provide a better view of the natural hair texture and pattern, enabling the barber or stylist to make informed decisions about the cut. Additionally, dampening the hair helps to keep flyaways and frizz at bay, resulting in a smoother and more controlled styling process. This practice contributes to achieving a clean, professional finish in the haircut.

The other options do not serve the primary purpose of using water during a haircut. Water does not affect hair color or make the hair heavier, and while it may help streamline the cutting process in terms of visibility and control, it does not inherently speed up the haircut itself. The main focus is on enhancing manageability and ensuring a polished end result.
