## Examples

- He noticed his hairline was starting to recede.
- The barber carefully trimmed the edges to create a sharp, clean hairline for the client.
- Genetic factors largely determine the shape of one's hairline, though environmental stressors and age can cause the follicles to thin over several decades.
