Folliculitis is a benign skin disorder characterised by inflammation of one or more hair follicles that appears as pinpoint red bumps and sometimes with a small dot of pus at the top on the skin. In folliculitis, many hair follicles in one area of the skin are affected
Folliculitis affects people of all ages, from babies to seniors. The disease is characterised by the numerous smooth little redbumps form around hair follicles, most common on the face, scalp, chest, back, buttocks, and legs with infection and inflammation .
Folliculitis may be caused by bacteria, yeast or another type of fungus. If the follicles are injured, they are more likely to become infected. Follicles may get irrirated because of using a hot tub, whirlpool, or swimming pool that is not properly treated with chlorine, with substances like makeup, cocoa butter, motor oil, tar, and creosote. Iron deficiency anemia is sometimes associated with chronic cases.
AIDS-associated eosinophilic folliculitis is seen in HIV patients with CD4+ count <300 cells/mm^3. A limited number of cases of eosinophilic pustular folliculitis have been observed in infants less than 1 year of age, with a male predominance.
