Folliculitis is a common inflammatory skin condition that affects your hair follicles. These are the openings in your skin that hold the roots of your hair.
It's usually caused by a fungal or bacterial infection that occurs when you damage your hair follicles. It can affect any part of your body that has hair, including your scalp.
The condition isn't contagious, and you can usually treat it at home. But in some cases, the infection can spread to other follicles and cause scarring or permanent hair loss.
Folliculitis initially causes small, red bumps that look similar to an acne breakout. Over time, it may spread to other follicles and the bumps may get larger and more inflamed.
