Folliculitis

Folliculitis

Folliculitis is the inflammation of one or more hair follicles. The condition may occur anywhere on the skin.

Causes

Most carbuncles and furuncles 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 staph 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.[http://www.nlm.nih.gov/medlineplus/ency/article/001460.htm Medline Plus (NIH) article on Hot tub folliculitis] 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.
