Scarring alopecias: a trichologic emergency.

Scarring or cicatricial alopecias represent a group of poorly understood and uncommon disorders that cause permanent hair loss. Scarring alopecias are regarded as trichologic emergencies as hair loss is irreversible, rapidly progressive, and can be disfiguring. Patients could experience tremendous anxiety, low self-esteem, and extreme psychosocial stress. Hence, prompt diagnosis and aggressive treatment are essential in the management of active primary scarring alopecias as early intervention may slow down or prevent further hair loss. This article will review different types of primary scarring alopecia in hopes of helping clinicians accurately diagnose these conditions as well as provide appropriate treatment.
