Folliculitis
Definition
Folliculitis is inflammation of one or more hair follicles. The condition may occur anywhere on the skin.
Alternative Names
Pseudofolliculitis barbae; Tinea barbae; Barber's itch
Causes
Folliculitis starts when hair follicles are damaged by friction from clothing, blockage of the follicle, or shaving. In most cases of folliculitis, the damaged follicles are then infected with the bacteria Staphylococcus (staph).
Barber's itch is a staph infection of the hair follicles in the beard 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 a fungus.
Pseudofolliculitis barbae is a disorder occurring primarily in black men. If curly beard hairs are cut too short, they may curve back into the skin and cause inflammation.
Symptoms
Common symptoms include a rash, itching, and pimples or pustules near a hair follicle in the neck, groin, or genital area. The pimples may crust over.
Exams and Tests
A diagnosis is primarily based on how the skin looks. Lab tests may show which bacteria or fungus is causing the infection.
Treatment
Hot moist compresses may promote drainage of extensive folliculitis. Treatment may include antibiotics applied to the skin (mupirocin) or taken by mouth (dicloxacillin), or antifungal medications to control the infection.
Outlook (Prognosis)
Folliculitis usually responds well to treatment, but may recur.
Possible Complications
- Folliculitis may return
- Infection may spread to other body areas
When to Contact a Medical Professional
Apply home treatment and call your health care provider if symptoms recur frequently, if they persist longer than 2 or 3 days, or if the infection spreads.
Prevention
To prevent further damage to the hair follicles and infection:
- Reduce friction from clothing.
- Avoid shaving the area if possible (if shaving is necessary, use a clean new razor blade or an electric razor each time).
- Keep the area clean.
- Avoid contaminated clothing and washcloths.
