Dermal Filler-Induced Alopecia: A Case Report and Literature Review

This document discusses a rare complication of dermal filler-induced alopecia, focusing on a case where a 21-year-old female experienced hair loss and skin necrosis after hyaluronic acid (HA) injections. The condition, linked to vascular compromise, was successfully treated with hyaluronidase, corticosteroids, minoxidil, and CO2 laser therapy, resulting in full hair regrowth and no scarring after 1 year. The report highlights that only 16 cases have been documented, mostly in women, with HA being the most common filler involved. It emphasizes the importance of early intervention and suggests using ultrasound guidance during injections to minimize risks.
