It is a chronic condition where people get itchy bumps on the back of the neck and scalp. It is most common in young, African American men. The bumps may result in thickened scars and patches of hair loss.
Scratching, rubbing, or shaving the back of your neck may cause or worsen AKN. Another cause may be an abnormal reaction to a bacterium called staphylococcus aureus.
While it's not clear how to prevent or cure AKN, the goal for treating AKN is to stop it from getting worse.
