What is Folliculitis?
Folliculitis is an inflammation of the hair follicles. Each hair on your body grows out of a tiny pouch called a follicle. You can have Folliculitis on any part of your body that has hair. But it is most common on the beard area, arms, back, buttocks, and legs.
What Causes Folliculitis?
It may be caused by bacteria. It also can be caused by yeast or another type of fungus. You may get Folliculitis if you have damaged hair follicles. Shaving or wearing clothes that rub the skin can irritate the follicles, which can lead to Folliculitis.
They also can become blocked or irritated by sweat, machine oils, or makeup. When the follicles are injured, they are more likely to become infected.
You are more likely to get Folliculitis if you:
• Use a hot tub, whirlpool, or swimming pool that is not properly treated with chlorine.
• Wear tight clothes.
• Use or work with substances that can irritate or block the follicles. Examples include makeup, cocoa butter, motor oil, tar, and creosote.
• Have an infected cut, scrape, or surgical wound. The bacteria or fungi can spread to nearby hair follicles.
• Have a disease such as diabetes or HIV that lowers your ability to fight infection.
Folliculitis usually looks like red pimples with a hair in the center of each one. The pimples may have pus in them, and they may itch or burn. When the pimples break open, they may drain pus, blood, or both.
“Hot Tub Folliculitis” most often appears about 72 hours after you’ve been in a hot tub or spa. Many small pimples appear on your stomach and sometimes on your arms and legs. You might have a mild fever and have an upset stomach. Most of the time, this kind of Folliculitis goes away on its own in 7 to 10 days.
How is Folliculitis Diagnosed?
Your doctor will check your skin and ask about your health and activities. He or she may do tests to find out what is causing your Folliculitis and to make sure you don’t have a different problem, such as impetigo or heat rash. Testing a sample of the fluid in the pimples or a sample of tissue can help your doctor learn what is causing the infection.
How is it Treated?
Mild Folliculitis usually heals on its own in about 2 weeks. You can take care of yourself at home with:
• Warm compresses made with saltwater or Burow’s solution. These may ease itching and help healing. To make a warm compress, soak a hand towel in warm water that you have added salt or Burow’s solution to. Wring out the excess water, and place the towel on the affected skin.
• Medicated shampoo. It can be used to treat Folliculitis on the scalp or beard.
If the inflammation gets worse or doesn’t go away, you may need to see your doctor. He or she may prescribe medicine, such as an antibiotic.
Call your doctor if you have Folliculitis and:
• It spreads or keeps coming back.
• You have a fever over 101°F (38°C).
• The affected area becomes red, swollen, warm or more painful.
If the inflammation doesn’t go away or keeps coming back, laser hair removal may be an option. Laser treatment destroys the hair follicles, so they can’t get inflamed.
How Can You Prevent Folliculitis?
• Bathe or shower daily with mild soap
• Shower after you exercise & after working around chemicals
• Avoid sharing towels, washcloths or other personal items
• Don’t scratch the bumps
• Avoid shaving the bumps. If you must shave, use a new blade each time
• Avoid using oils on your skin. Oils can trap bacteria in skin pores & cause Folliculitis.
• After you use public hot tubs or spas, shower right away with mild soap
• If you own a hot tub, follow proper sanitation to keep it clean
