Folliculitis is a common skin condition that occurs when a hair follicle becomes blocked and inflamed. It is often caused by a bacterial infection and can occur anywhere on the body where hair exists. The lower legs are often affected due to hair removal practices and irritation from clothing. There are different types of folliculitis, depending on the cause, infectious organism and effect on the skin.

Symptoms
Hair follicles are exposed to bacteria and other matter from the outside world which can cause inflammation or infection. Inflammation typically results in swelling. Folliculitis can present as clusters of small bumps or pimples around a hair follicle. These bumps can be pus-filled making them appear white and may feel itchy, burn or be tender to the touch. Redness around the folliculitis bump is common and is another indication of inflammation.

Causes
An infected hair follicle can be caused by improper shaving technique, poor personal hygiene and wearing tight clothes over the legs that rubs and prevents air flow. Microorganisms such as bacteria, are commonly present on the surface of the skin and can easily infect an exposed follicle. There are several risk factors for folliculitis including frequent shaving, history of diabetes, participating in activities that cause sweating and failing to wash the skin afterwards and sitting in a hot tub that is not properly cleaned.

Treatment
Treatment of folliculitis depends on the type and mild cases can usually be treated at home with regular washing of the skin on the legs using soap and water. An antibacterial soap may be required to more effectively wash away the bacteria causing infection. A warm compress can help as can application of an antibacterial cream. Regular laundering of clothes is important to improve personal hygiene and reduce the presence of microorganisms that could pose a risk. If folliculitis is widespread on the lower legs, it is best to seek the advice of a primary care professional to avoid a more serious infection.
