Pseudofolliculitis barbae; Tinea barbae; Barber's itch
Folliculitis is inflammation of one or more hair follicles. It can occur anywhere on the skin.
Folliculitis starts when hair follicles are damaged by friction from clothing, blockage of the follicle, or shaving. In most cases of folliculitis, the damaged follicles are then infected with the bacteria Staphylococcus (staph).
Barber's itch is a staph infection of the hair follicles in the beard area of the face, usually the upper lip. Shaving makes it worse. Tinea barbae is similar to barber's itch, but the infection is caused by a fungus.
Pseudofolliculitis barbae is a disorder that occurs mainly in black men. If curly beard hairs are cut too short, they may curve back into the skin and cause inflammation.
