Pseudofolliculitis barbae and folliculitis keloidalis nuchae are chronic follicular disorders disproportionately affecting men of African ancestry. This article explores the etiology, pathogenesis, treatment, and prevention strategies of these conditions. Effective treatment and prevention of these disorders involves pharmacologic and procedural interventions as well as behavioral modifications.
Key points
- •
Pseudofolliculitis barbae (PFB) is an inflammatory follicular disorder associated with shaving, most commonly seen in men of African ancestry.
- •
Follicular penetration from ingrown hairs is the primary inciting factor in PFB.
- •
In the appropriate patient, an effective prevention strategy for PFB is to grow a beard, but optimization of shaving practices (including pre- and postcare) is a useful approach for men who wish to continue shaving.
- •
Folliculitis keloidalis nuchae (FKN) is a follicular-based disorder mainly affecting the nape of the neck; histopathologically, FKN has characteristics of a primary cicatricial alopecia.
- •
PFB and FKN are chronic conditions requiring continual maintenance strategies.
