Infectious folliculitis is an infection of the upper portion of the hair follicle, characterized by a follicular papule, pustule, erosion, or crust at the follicular infundibulum; the involvement can extend deeper to the entire length of the follicle (sycosis).
Folliculitis develops when bacteria, such as Staphylococcus, or a fungus enters the body through a cut, scrape, surgical incision, or other break in the skin near a hair follicle. Scratching the affected area can trap fungus or bacteria under the fingernails and spread the infection to hair follicles on other parts of the body.
