What direction do you shave a patient's leg hair?

• A. Direction of hair growth
• B. Perpendicular to hair growth
• C. Against hair growth
• D. Diagonal to hair growth

Answer: (C)

Shaving against the direction of hair growth is used to obtain the closest shave. When you shave opposite to how the hair grows, you cut the hairs at their base, leaving the skin smoother and hair removed more completely. This is often desired in clinical prep to ensure a smooth area for procedures, dressings, or accurate skin treatments, and it helps prevent hair stubs from remaining above the surface.

Using a clean blade, warm water, and soap with gentle strokes minimizes skin irritation and reduces the risk of nicks, especially on legs where skin can be sensitive. If the skin is irritated or there are broken areas, it’s best to avoid shaving or proceed with extreme care.

Shaving with the grain or in other directions tends to leave longer hairs and a less even surface, which is why they are not chosen for achieving the closest, most uniform result.
