Folliculitis is an infection of the hair follicles, which are the
small pouches in the skin from which hairs grow. Folliculitis can develop on
any part of the body that has hair but is most common on the face, scalp, and
areas rubbed by clothing, such as the thighs and groin.
The most common cause of folliculitis is bacteria. But it may
also be caused by a fungus.
Folliculitis begins as a red, tender area at or near the base of
one or more strands of hair. It usually looks like red pimples with a hair in
the center of each one. The pimples may have pus in them, and they often itch
Mild folliculitis usually heals on its own in about 2 weeks. Oral
antibiotics or antifungal medicines usually work to clear up
deeper, more severe infections.
