is the inflammation
of one or more hair follicles
. The condition may occur anywhere on the skin
and other cases of folliculitis develop from Staphylococcus aureus
Folliculitis starts when hair follicles are damaged by friction from clothing, blockage of the follicle, shaving or too tight braids too close to the scalp [traction folliculitis]. In most cases of folliculitis, the damaged follicles are then infected with the bacteria Staphylococcus (staph).
Iron deficiency anemia is sometimes associated with chronic cases
- Sycosis barbae or Barber's itch is a staphylococcus infection of the hair follicles in the bearded area of the face, usually the upper lip. Shaving aggravates the condition.
- Tinea barbae is similar to barber's itch, but the infection is caused by the fungus T. rubrum.
- Pseudofolliculitis barbae is a disorder occurring primarily in men of African descent. If curly beard hairs are cut too short, they may curve back into the skin and cause inflammation.
- Hot tub folliculitis is caused by the bacteria Pseudomonas aeruginosa often found in new hot tubs. The folliculitis usually occurs after sitting in a hot tub that was not properly cleaned before use. Symptoms are found around the body parts that sit in the hot tub -- typically the legs, hips, and buttocks and surrounding areas. Symptoms are typically amplified around regions that were covered by wet clothing, such as bathing suits.
- rash (reddened skin area)
- pimples or pustules located around a hair follicle
- itching skin
- spreading from leg to arm to body through improper treatment of antibiotics
- Topical antiseptic treatment is adequate for most cases
- Topical antibiotics such as mupirocin or neomycin containing ointment
- Some patients may benefit from systemic narrow-spectrum penicillinase-resistant penicillins (such as dicloxacillin in US, or flucloxacillin in UK)
