PSEUDOFOLLICULITIS BARBAE

• Pseudofolliculitis barbae (PFB - "razor bumps") is a chronic recurrent inflammatory skin condition

• PFB is more common in patients with darker skin types and curly hair. 

• It can present with itching, pain, bumps, puss-filled bumps, scarred bumps in an area previously shaved. Lesions can be reddish-purple and/ or dark.

• PFB risk factors include genetic predisposition,  the curved shape of the hair follicle, the structure of the hair, and hair grooming practices (e.g. use of multiple blade razor).

• Management includes improved shaving techniques (e.g removal of trapped hairs, cessation of shaving, electric clippers), topical keratolytics (e.g. retinoids, salicylic acid, and alpha-hydroxy acids), topical anti-inflammatory agents, topical antibiotics, oral antibiotics, topical steroids, topical skin lighteners (e.g. hydroquinone, azelaic acid), chemical peels, lasers
