Short answer : WHY ???
Shaving against the grain can lead to several skin issues despite the appeal of a closer shave. Here are the main reasons why it is generally advised against:
Increased Risk of Skin Irritation
Shaving against the grain often results in skin irritation, razor burn, and discomfort. When the razor pulls the hair before cutting it, it can cause the hair to be tugged back against the skin, leading to inflammation and sensitivity
Ingrown Hairs
One of the most significant drawbacks of shaving against the grain is the increased likelihood of ingrown hairs. This occurs when hair is cut too short or at an angle that causes it to curl back into the skin as it grows. The result can be painful bumps and irritation, commonly referred to as "razor bumps" or "strawberry legs"
Compromised Skin Health
Shaving in this manner can damage hair follicles and increase the chances of developing razor burn. This condition manifests as red, inflamed patches on the skin, which can be uncomfortable and unsightly24. The process of pulling hair against its natural growth direction can also lead to micro-abrasions on the skin's surface, exacerbating irritation
Conclusion
While some individuals may tolerate shaving against the grain without significant issues, many experience adverse effects such as irritation and ingrown hairs. For a more comfortable shaving experience, it's often recommended to shave with the grain, especially for those with sensitive skin or coarse hair. If a closer shave is desired, consider using proper techniques and tools rather than compromising skin health by shaving against the grain124.
