There are two types of folliculitis:
Superficial Folliculitis affects the upper area of the hair follicle and may cause red, inflamed skin, small clusters of red bumps, blisters that break open and crust over and/or itchiness and tenderness. When the infection occurs in men’s beards, it is called Barber’s Itch.. When it is caused by a fungal infection, it is known as Tinea Barbae (ringworm).
Deep Folliculitis affects the entire follicle from its deepest parts under the skin to the surface of the skin. This less-common form of folliculitis is seen in people who are undergoing chronic acne antibiotic treatment, people with HIV or people with boils and carbuncles.
