Answer

The primary lesion is a flesh-colored or erythematous papule with a hair shaft in its center. If the hair shaft is gently lifted up, the free end of the hair comes out of the papule. These inflammatory papules are seen in shaved areas adjacent to the follicular ostia, as shown in the image below.

Pustules and abscess formation can occur from secondary infection.

Postinflammatory hyperpigmentation, scarring, and keloid formation may occur in chronic or improperly treated cases.
