Pseudofolliculitis barbae

Pseudofolliculitis barbae is a common skin condition that affects the hair follicles in the beard area, primarily in people who shave. It occurs when shaved hairs grow back into the skin instead of outward, causing inflammation, red bumps, and sometimes pain or itching. This condition mainly involves the skin and hair follicles on the face and neck. It can lead to discomfort and visible skin changes, such as dark spots or scarring if it becomes chronic. The main health impact is cosmetic and discomfort related to the irritated skin and bumps.

Pseudofolliculitis barbae is a chronic inflammatory disorder of the hair follicles caused by ingrown hairs following shaving, especially in individuals with tightly curled hair. The core pathology involves hair shafts that re-enter the epidermis or dermis, triggering a foreign body inflammatory reaction. This leads to the formation of papules, pustules, and sometimes keloid-like scarring. It is most common in men of African descent due to the hair's curvature and growth pattern. The condition is significant because it can cause persistent follicular inflammation, secondary infection, and permanent skin changes such as hyperpigmentation and scarring.
