Folliculitis
Folliculitis is a common skin condition that occurs when the hair follicles on the skin become infected or inflamed. It can cause redness, itching, and swelling around the affected area, and may also lead to the formation of pus-filled pimples or abscesses. Folliculitis can be caused by bacterial infections, such as staphylococcus aureus, or by ingrown hairs, and can occur anywhere on the body, but is most common in areas with high hair density, such as the face, neck, chest, and back.
