Mild cases will be tender and itchy, but in severe cases where the entire follicle becomes involves, lesions may become painful. Lesions may erupt and become crusted. Acne necrotica is a rare, severe form of scalp folliculitis, which consists of larger papules which inflame, then develop a black crust. These lesions leave permanent scars, and the condition may affect other areas, including the face.

All age, gender and ethnic groups can develop scalp Folliculitis. It is commonly due to an infection of the skin by bacteria. Conditions such as diabetes, weakened immune systems, underlying skin conditions, obesity, warm humid climates, and excessive sweating can increase a person's susceptibility to the condition.
