A follicle refers to a crust or cavity from which the hair emerges on the surface of the skin. The term folliculitis is used to describe the inflamed condition of the hair. Depending upon the causal organism, folliculitis causes can be characterized as follows:

Viral Folliculitis
Parasitic Folliculitis

These are more serious than folliculitis and can cause permanent damage and scarring to the skin.
