course and prognosis

Infected hairs are easily removed, although new papules or pustules frequently develop. Folliculitis may become a chronic condition when it affects areas where the hair follicles are deep in the skin. This is most common in the beard (sycosis barbae). Conventional medicine uses oral antibiotics promptly to avoid developing a chronic condition. If the infection worsens, a furuncle or carbuncle can develop, requiring more extensive treatment. A furuncle is a more heavily infected nodule which may exude necrotic, purulent material. Carbuncles are groups of furuncles which cause serious subcutaneous necrosis They are most common in patients with underlying diseases.

differential diagnosis
