Folliculitis is inflammation or infection of one or more
hair follicles (openings in the skin that enclose
hair).It can develop
on any part of the body, but is most likely to occur on the scalp, face, or parts of the arms, armpits, or legs not usually covered by clothing.
Scratching the affected area can trap fungus or bacteria under the fingernails and spread the infection to hair follicles on other parts of the body.Never try to pop them as you will only aggravate the condition.
