Pseudofolliculitis barbae - Skin
Methods of close shaving that predispose to the development of pseudofolliculitis barbae include using razors with multiple blades, plucking hairs with tweezers, shaving against the grain of hair growth, and pulling the skin taut while shaving. Pseudofolliculitis barbae is primarily a cosmetic concern, but it can lead to scarring, infection, hyperpigmentation, and keloid formation.
Pseudofolliculitis pubis is a similar condition that occurs in the genital area after pubic hair is shaved. Shaving of the axillae may cause a similar condition.
