Folliculitis

Folliculitis is the infection and inflammation of one or more hair follicles. The condition may occur anywhere on hair-covered skin. The rash may appear as pimples that come to white tips on the face, chest, back, arms, legs, buttocks, or head.
Causes.
Most carbuncles, boils, and other cases of folliculitis develop from "Staphylococcus aureus".
Folliculitis starts with the introduction of a skin pathogen to a hair follicle. Hair follicles can also be damaged by friction from clothing, an insect bite, blockage of the follicle, shaving, or braids that are very tight and close to the scalp. The damaged follicles are then infected by "Staphylococcus". Folliculitis can affect people of all ages.
Iron deficiency anemia is sometimes associated with chronic cases.
Complications.
Condition can develop into a more severe skin condition such as cellulitis or abscess.
Treatment.
Most simple cases will resolve on their own but first line treatments are typically topical medications.
Folliculitis may recur even after symptoms have gone away.
