What Is Folliculitis?

Folliculitis is inflammation of one or more hair follicles due to infection from bacteria or damage caused by friction or blockage of sebaceous glands. These glands naturally produce oil that protects the skin. Interference causes the body to react defensively to fight infection.

Signs

Depending on the infection type, the area can be a one-half inch in size or much larger with the following characteristics:
• Red, inflamed
• Swollen and pus-filled
• Itchy
• Painful
Folliculitis can also present as pimple-like clusters.

Affected areas

Anywhere on the body where there is hair growth, folliculitis can occur. Generally "hairy" parts of the body are more prone like the face, underarms, thighs and groin areas.

Considerations

Several health conditions make a person more susceptible to folliculitis. These conditions include diabetes, weak immune system, obesity and fungal and viral infections. Living near excessive moisture and working in auto shops adds risk.

Treatment

Applying hot compresses to bring the area to a head encourage drainage and relieve inflammation. Over-the-counter topical antibiotic creams or ointments help heal and fight infection for surface lesions. If lesions are deep in the skin and have not improved in about three days, it is best to see a physician for further treatment.

Prevention

Keep skin clean and dry from moisture or perspiration. Refrain from wearing tight clothing as this promotes friction and can irritate the skin. Use clean dry towels when bathing. Use clean blades for shaving or consider using one of many different depilatories available for men and women.
