Shaving can contribute to ingrown hairs when cut hairs curl back toward the skin or become trapped beneath its surface. Friction and naturally curly or coarse hair can also play a role.
That's why bumps can appear around the beard line, neck, bikini line, underarms, and legs—even when you take care while shaving.
The takeaway: Don't focus on hair removal alone. Pay attention to how you care for your skin afterward, too.
