Which part of the body is most commonly affected by folliculitis?

Folliculitis often affects the bearded areas of the face due to the presence of hair follicles that can become inflamed or infected. The condition arises when hair follicles become clogged, usually by bacteria, resulting in inflammation, redness, and sometimes pus. Areas of the face where hair is actively growing, such as the beard zone, are particularly susceptible to this irritation, especially in individuals who shave or trim facial hair regularly.

While folliculitis can occur on other parts of the body, such as the scalp, hands, fingers, and back, the bearded areas are more prone due to the combination of hair growth and the potential for irritation from shaving products, tools, and environmental factors. This targeted predisposition makes the bearded areas of the face the most common site for this skin condition.
