Where do pimples or pustules typically form in cases of folliculitis?

Pimples or pustules in cases of folliculitis typically form in areas where hair follicles are present, and common sites include the neck and underarms. Folliculitis is an infection or inflammation of the hair follicles, often caused by bacteria or fungi, and tends to occur in areas that are prone to friction, sweat, and trapped bacteria. The neck can be affected due to shaving, while the underarm region is susceptible because it is often warm and moist, creating an ideal environment for infection. Therefore, identifying hair follicles on the neck and underarm as the typical sites for pustule formation aligns with the nature of folliculitis and how it commonly presents.
