Beware of the Impostors—Scalp Pathology Primer for the Hair Transplant Surgeon

Abstract

Histopathological features are important for the practicing hair transplant surgeon to ensure proper case selection, diagnosis, choice of proper treatment, and successful outcome. While the primary focus of the hair transplant surgeon is androgenetic alopecia (AGA), it is important to be aware of other conditions that can mimic AGA, whose treatment may be different. This article outlines some of these conditions such as scarring alopecias, alopecia areata, etc., and how to distinguish them. Proper identification will ensure proper treatment and avoid potential missteps in management.
