* Low density: Fewer hairs per square inch/centimeter compared to a full beard.
* Patchiness: Uneven growth, with areas where hair is either completely absent or very thin.
* See-through appearance: The skin underneath the beard is easily visible due to the lack of density.
Sparse beards can vary in severity. Some men might have a mostly full beard with a few thin spots, while others might have only a light dusting of hair across their face.
