Final answer:
When shaving, a gliding stroke is used with the grain of the hair to reduce the risk of irritation and cuts.
Step-by-step explanation:
In the field of barbering or grooming, when shaving, a gliding stroke is typically used with the grain of the hair. This means that the stroke is directed in the same direction as the hair growth.
Shaving with the grain helps to reduce the risk of irritation, ingrown hairs, and cuts. It allows for a smoother and more comfortable shave.
In contrast, shaving against the grain (option B) can result in a closer shave, but it increases the likelihood of skin irritation and ingrown hairs.
