Primary scarring alopecias (PSAs) are poorly understood dermatologic disorders that result in permanent hair loss. Most of the scarring alopecias involve a painful course, with individuals reporting scalp pain, burning, itching, or tingling/crawling sensations that can ultimately impact physical and psychological health. There has been no study of topical neurogenic agents, such as gabapentin, to treat scarring alopecia. However topical gabapentin has been safely used in other conditions associated with chronic pain, burning, irritation, itch, or tingling, such as vulvodynia. This study will serve as a pilot study to determine the efficacy and safety of topical gabapentin in the treatment of symptomatic scarring alopecia. In this study, 10 subjects with symptomatic lymphocytic-type scarring alopecia will be recruited and treated with topical gabapentin. Disease burden will be evaluated before and after 12 weeks of treatment through reporting of subjective symptomatology via surveys/questionnaire, neurometer study, clinical assessment, and biopsies measuring levels of CGRP before and after treatment.
