The bumps that make up a rash caused by folliculitis can be irritating and painful, but they are not an uncommon occurrence. Because folliculitis occurs in a hair follicle, anyone can develop this condition at any time. Even celebrities with amply insured limbs aren't immune.
Every person has small pockets from which hairs grow, known as hair follicles. Though hair follicles are most concentrated on your head, they appear everywhere on your body except the palms of your hands, the soles of your feet and any mucous membranes, like your lips [source: Mayo Clinic].
If something damages the follicle, irritation or infection -- folliculitis -- can arise. Many daily activities can damage hair follicles, such as shaving or wearing tight clothes that rub against a follicle. Sweat, oil and makeup can also clog hair follicles. Once a follicle is damaged, it is far more likely to become infected [source: WebMD].
Several different substances can infect a hair follicle. Most often, folliculitis infections are caused by the common bacteria known as staph (or Staphylococcus). Infections can also occur when yeast or fungus invades a hair follicle [source: WebMD].
Luckily, these types of infections are highly treatable by several different methods. Read on to find out how to put a stop to your folliculitis.
