Folliculitis
Folliculitis, single lesion
SpecialtyDermatology

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.[1]

Although acne can often involve superficial infection and inflammation of some hair follicles, the condition of those follicles is usually not called folliculitis, as that term is usually reserved for the separate set of disease entities comprising infected and inflamed hair follicles with causes other than acne.

Signs and symptoms[edit]

Complications[edit]

This condition can develop into a more severe skin condition, such as cellulitisorabscess.[1]

Causes[edit]

Most carbuncles, boils, and other cases of folliculitis are infected with Staphylococcus aureus.[1]

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,[2] blockage of the follicle, shaving, or braids that are very tight and close to the scalp. The damaged follicles are then infected by Staphylococcus spp. Folliculitis can affect people of all ages.[citation needed] Iron-deficiency anemia is sometimes associated with chronic cases.[citation needed]

Bacterial[edit]

Fungal[edit]

Mites[edit]

Viral[edit]

Noninfectious[edit]

Treatment[edit]

Most simple cases resolve on their own, but first-line treatments are typically topical medications.[1]

  1. Topical antiseptic treatment is adequate for most cases.
  2. Topical antibiotics, such as mupirocinorneomycin/polymyxin B/bacitracin ointment may be prescribed. Oral antibiotics may also be used.
  3. Some patients may benefit from systemic narrow-spectrum penicillinase-resistant penicillins (such as dicloxacillin in the US or flucloxacillin in UK).
  4. Fungal folliculitis may require an oral antifungal such as fluconazole. Topical antifungals such as econazole nitrate may also be effective.[1]

Folliculitis may recur even after symptoms have gone away.[citation needed]
