Post herpetic itch (PHI) is a less commonly reported sequela of herpes zoster. It can begin upon the resolution of the lesions or several weeks later. PHI is neuropathic in nature and is said to be caused by neural injury in the form of demyelination of itch-transmitting nerve fibers in the skin. The majority of PHI resolves over weeks to months with symptomatic treatment. We report a case of PHI resulting in frictional alopecia of eyebrows and scalp due to frequent rubbing of the skin and hairs secondary to bothersome neuropathic itch.
