Pseudofolliculitis barbae

Uncommon card · No. 175444

Pseudofolliculitis barbae (PFB) is a type of irritant folliculitis that commonly affects people who have curly or thick facial hair. It occurs when hair curls back into the skin after shaving, causing inflammation, redness, and bumps. This can lead to ingrown hairs, scarring, itchiness, and skin discoloration. PFB can be treated with various methods, including changing shaving habits, using topical creams or ointments, and undergoing chemical-, or laser hair removal. Prevention measures include making changes to one's shaving technique: using sharp razors, avoiding too close a shave, using an astringent — such as alum — and an antiseptic — such as alcohol-based aftershave after shaving. It was first described in 1956.
