| Folliculitis is a superficial or deep infection and inflammation of hair follicles usually arising from blockage of the associated oil (sebaceous) gland. The infection and inflammation may spread to areas around the affected follicles. Folliculitis can be bacterial (most often Staphylococcus), fungal (Candida), or viral (herpes simplex or molluscum contagiosum).
Factors that promote folliculitis include shaving, friction from clothing, athletic padding, mineral oil on the skin, and the use of wax to remove hair (wax epilation). Folliculitis may occur anywhere on the skin surface but is commonly found on the extremities, scalp, and face. It usually occurs in areas with short, coarse hairs. Chronic folliculitis of the bearded area is called barber's itch (sycosis barbae).
Less common causes of folliculitis are the Klebsiella, Proteus, and pseudomonas bacteria. Klebsiella or Proteus can cause folliculitis in individuals on long-term antibiotic treatment for acne. Pseudomonas causes "hot tub" or "spa pool" folliculitis and is contracted by individuals using a contaminated, inadequately chlorinated hot tub. Hot tub folliculitis may also be contracted from swimming pools or a contaminated sponge or loofah.Risk: Folliculitis is more common in people who are immunocompromised, obese, and those with diabetes (Cyr). Additional risk factors include individuals who have pre-existing dermatitis, hyperhidrosis, frequent hot tubs, and shave or wax regularly. Barber's itch is most common in black males. Incidence and Prevalence: Folliculitis is a common skin infection. However, incidence of chronic folliculitis is low. |
