The key to a perfectly smooth shave is often the most overlooked step: mapping the grain. 

What is mapping the grain? 

Mapping the grain is examining your facial hair growth patters. These patterns don’t change and dictate your shave direction to minimize skin irritation (bumps, ingrown hair, redness, etc.).

How do I map my grain?

For best results, have 2-3 days of facial hair growth. If your facial hair is too short you won’t be able to see the direction the hair is growing. If it’s too long your hair may curl, concealing the pattern.

Your facial hair will likely change directions across your face. We recommend examining the following 5 sections:

  1. Left cheek
  2. Right cheek
  3. Underneath your chin
  4. Left side of your neck
  5. Right side of your neck
Why Mapping the Grain Matters when Shaving

While examining these sections in the mirror, look to see if there is a specific direction the hair is growing. Hair can grow vertically, horizontally, or diagonally. 

When running your fingers over your facial hair, the “with the grain” direction will feel smooth – like you’re pushing down the hair. The “against the grain” direction will feel rough – like you’re pushing up the hair.

Once you’ve mapped the grain of your face you’re ready to start shaving.

With any single blade razor, multiple passes are the key to a successful shave. Each pass progressively removes the hair closer to the skin. In three passes, you’ll have that baby butt smooth shave we are all after. 


No shaving cream? No shaving. Running a razor over an area of skin that is not lubricated is a big no-no. This is the main cause of razor burn, ingrown hairs, and irritation. Make sure to re-apply shaving cream before each pass.
