Understanding Hair Growth Below the Lip: Chin Hair, Mustache & More

A tuft of hair right below the upper lip on the chin is typically called a "chin hair" or "chin fuzz".

You might also hear it called a "lip hair" or "upper lip hair" if it's specifically located directly below the lip.

However, the term "mustache" is generally used for a longer, more pronounced growth of hair on the upper lip, not the area below it.
