The direction of hair growth is a key consideration when shaving. This direction, often referred to as the grain, is the path the hair follicle takes as it emerges from the skin. For instance, on the cheek, hair might grow downwards, while on the neck it may grow upwards or sideways. Identifying this direction is the first step toward a comfortable shave.
Adhering to the natural direction of hair growth minimizes irritation and ingrown hairs. This technique reduces the stress on the skin, leading to a smoother and less inflamed post-shave result. Historically, barbers have recognized this principle as foundational to preventing skin problems associated with hair removal.
